Revert ubi-tools changes

Restore ubi tools to their "original" state, which means to
the state they were before I stareted cleaning them up.

Instead, create a "new-utils" subdirectory and move my work
there.

+system directly using pfiflash, or ubimkvol, ubirmvol, ubiwritevol.
+
+The latter is the case when there is already Linux running which has

+
+!!! NOTICE !!!
+If you execute ./configure in the top_level directory the helper Makefile
+gets overwritten. Thats actually no problem, but be aware of that.
+
+1. Build Process
+
+1.1 Build, install and forget
+    o Build all and everything
+      $make all (takes a while, builds ppc and x86 binaries/libs)
+    o Installation:
+      $make install
+    o Uninstallation:
+      $make uninstall
+
+    o x86 only would be:
+      $make x86 && make install_x86
+    
+1.2 Usage for a developer
+
+    1.2.1 The build process in detail
+
+    o If you've checked out the sources from the CVS repository you'll find a
+      directory setup like this:
+
+	flashutils/
+	-rw-r--r--  1 olli olli 1.3K Mar 14 11:53 Makefile
+	-rw-r--r--  1 olli olli 1.9K Mar 14 10:50 Makefile.am
+	-rwxr-xr-x  1 olli olli  265 Mar  9 00:47 bootstrap
+	-rw-r--r--  1 olli olli 1.1K Mar  9 16:55 configure.ac
+	drwxr-xr-x  2 olli olli 4.0K Mar  9 00:28 doc
+	drwxr-xr-x  2 olli olli 4.0K Mar 14 11:56 inc
+	drwxr-xr-x  2 olli olli 4.0K Mar 14 11:56 lib
+	drwxr-xr-x 17 olli olli 4.0K Mar 13 16:50 src
+
+    o To generate the initial build templates you have to  call the bootstrap
+      script:
+      $ ./bootstrap
+    o Create a directory for the target platform 
+      $ mkdir build_x86
+    o Descend into the directory and call the top-level configure script
+      with the desired options.
+      $ cd build_x86
+      $ ../configure --prefix=/usr/local [...]
+    o Now you'll find a directory structure like this:
+      
+	flashutils/build_x86/
+	-rw-r--r-- 1 olli olli  47K Mar 14 13:33 Makefile
+	-rw-r--r-- 1 olli olli  33K Mar 14 13:33 config.log
+	-rwxr-xr-x 1 olli olli  38K Mar 14 13:33 config.status
+	drwxr-xr-x 2 olli olli 4.0K Mar 14 13:33 inc
+	drwxr-xr-x 3 olli olli 4.0K Mar 14 13:33 lib
+	-rwxr-xr-x 1 olli olli 202K Mar 14 13:33 libtool
+
+    o The config.guess script can be used to update the Makefiles in the
+      target directory after a change of the top-level template files 
+      (i.e. the Makefile.in files).
+      $ ./config.guess
+    o To compile everything for this platform just invoke make in
+      flashutils/build_x86:
+      $ make
+      or from toplevel:
+      $ make -C ./build_x86
+    o The build process creates a new directory "bin":
+	flashutils/build_x86/
+	[...]
+	drwxr-xr-x 3 olli olli 4.0K Mar 14 13:41 bin
+	[...]
+
+      This directory contains all binary files which will be installed
+      by make install, e.g.:
+
+	flashutils/build_x86/bin/
+	-rwxr-xr-x 1 olli olli 7.2K Mar 14 13:41 bin2nand
+	-rwxr-xr-x 1 olli olli  15K Mar 14 13:41 mkbootenv
+	-rwxr-xr-x 1 olli olli  16K Mar 14 13:41 pddcustomize
+	-rwxr-xr-x 1 olli olli  36K Mar 14 13:41 pfi2bin
+	-rwxr-xr-x 1 olli olli 6.8K Mar 14 13:41 pfiflash
+	-rwxr-xr-x 1 olli olli 5.0K Mar 14 13:41 ubicrc32
+	-rwxr-xr-x 1 olli olli  13K Mar 14 13:41 ubigen
+	-rwxr-xr-x 1 olli olli 6.3K Mar 14 13:41 ubimirror
+
+
+    1.2.2 Modifying and Adding Sources
+
+    o There is a dedicated directory which contains all source code
+      of the flashutils package, e.g.:
+
+	flashutils/src/
+	drwxr-xr-x 2 olli olli 4.0K Mar 13 11:42 libbootenv
+	drwxr-xr-x 2 olli olli 4.0K Mar 13 11:42 liberror
+	drwxr-xr-x 2 olli olli 4.0K Mar 13 16:48 mkpfi
+	drwxr-xr-x 2 olli olli 4.0K Mar 13 16:12 pddcustomize
+
+      
+      
+      The prefix "lib" is used to mark directories as part of a convenience
+      library. Binaries have no special prefix.
+
+    o How to add sources?
+      
+      Just create a new directory at flashutils/src/, e.g.:
+
+      For a binary:
+      $ mkdir rider
+      $ cd rider
+      $ vi rider.c
+      /* do sth with that file... */
+
+      For a convenience library (as well as for "normal libs")
+      $ mkdir libworld
+      $ cd libworld
+      $ vi world.c
+      /* do sth with that file... */
+
+    o How to register sources in the build process (for binaries)?
+
+      You have to register your sources at the top-level automake Makefile:
+
+      In directory flashutils/
+      $ vi Makefile.am
+
+      Binaries have to be registered at "bin_PROGRAMS", e.g.:
+	bin_PROGRAMS	= bin/pddcustomize \
+			  bin/rider
+
+      Add the rule how the binary is assembled, e.g.:
+	bin_pddcustomize_SOURCES = \
+		$(top_srcdir)/src/pddcustomize/pddcustomize.c 
+	bin_pddcustomize_LDADD   = \
+		$(top_builddir)/lib/libbootenv.la \
+		$(top_builddir)/lib/liberror.la 
+
+	bin_rider_SOURCES = \
+		$(top_srcdir)/src/rider/rider.c
+
+      This example reflects a simple build process for "rider". "rider"
+      is built without any other dependencies or convenience libraries.
+      The example for pddcustomize is a bit more complicated.
+      "_LDADD" adds some convenience libraris into the link process of 
+      "pddcustomize". Imagine, that your "rider" has common code 
+      with "dragon_bin" which is held in a library called "libworld".
+      The build rules would like like the following:
+
+	bin_rider_SOURCES = \
+		$(top_srcdir)/src/rider/rider.c
+	bin_rider_LDADD   = \
+		$(top_builddir)/lib/libworld.la 
+
+	bin_dragon_SOURCES = \
+		$(top_srcdir)/src/dragon_bin/dragon_bin.c
+	bin_dragon_LDADD   = \
+		$(top_builddir)/lib/libworld.la 
+
+      Don't forget to add "dragon" to "bin_PROGRAMS"!
+      Don't forget to set the build rule for the "libworld" itself!
+      This is documented in the next section.
+      	
+
+    o How to register sources in the build process (for libraries)?
+
+      Until now we didn't care about the build process of "libworld".
+      Libraries are handled special in this build process because
+      they are handled as "modules", i.e. they are able to be built
+      without building the binaries in the same step. Additionally,
+      it is possible to assemble complex libraries out of simple ones.
+      That especially makes sense if you want to export (install) a 
+      library on a system which uses some common code and makes
+      some adoptions for usability and presents a comfortable interface to
+      the user (see libpfiflash in the sources for an example).
+
+    o Registering "libworld" as convenience library.
+
+      Instead of editing the "Makefile.am" in "flashtools/", we have to 
+      edit now the "Makefile.am" in "flashtools/lib/":
+
+	noinst_LTLIBRARIES	= libworld.la 
+
+	libworld_la_SOURCES	= $(top_srcdir)/src/libworld/world.c
+
+    o Registering "libworld" as library which gets installed.
+      
+	lib_LTLIBRARIES		= libworld.la 
+	libworld_la_SOURCES	= $(top_srcdir)/src/libworld/world.c
+	libworld_la_LDFLAGS	= -no-undefined -version-info 0:0:0
+
+    o Header files
+      
+      All header files are stored at "flashutils/inc", regardless
+      if convenience library or not. 
+
+      If you want to export headers you have to specify this in the Makefile.am
+      located at "flashutils/inc", e.g. (this should not be done 
+      for convenience libraries):
+
+         nobase_include_HEADERS = world.h

+.TH UNUBI 1 "NOVEMBER 2006" FSP "FSP Flashutils"
+.SH NAME
+unubi \- extract volumes/eraseblocks from a raw\-UBI image
+.SH SYNOPSIS
+\fBunubi [\-aevEV] [\-d \fIout\-dir\fB] [\-r \fIvolume\-id\fB]
+[\-b \fIblock\-size\fB] \fIimage\-file
+.SH DESCRIPTION
+.PP
+\fBunubi\fR reads an image file containing blocks of UBI headers and data
+(such as produced from \fBnand2bin\fR) and rebuilds the volumes within.
+The default operation (when no flags are given) is to rebuild all valid
+volumes found in the image. \fBunubi\fR can also read straight from the
+onboard MTD device (ex. /dev/mtdblock/NAND).
+.SH OPTIONS
+.IP "\-a, \-\-analyze"
+When flagged, analysis files are generated within the output directory. These
+may include tables and or graphs detailing statistics gathered from the
+eraseblock data. Files are prefixed `analysis_'.
+
+See \fBANALYSIS\fR.
+.IP "\-b, \-\-blocksize \fIblock\-size\fR"
+Specify in bytes the \fIimage\-file\fR eraseblock size. Sizes may be
+postfixed with `KiB' or `MiB' to indicate mebibytes or kibibytes
+respectively. Default is 128KiB.
+.IP "\-d, \-\-dir \fIoutput\-dir\fR"
+Specify the output directory. If no directory is specified, the default
+is `unubi_\fIimage\-file\fR' within the curent working directory. If the
+attempt to create the output directory fails,
+.B unubi
+will try to create it in /tmp before aborting.
+.IP "\-e, \-\-eb\-split"
+When flagged, images are created for each eraseblock in \fIimage\-file\fR
+regardless of its validity. Each image is the complete eraseblock, including
+headers and any space to the end of the eraseblock after where the data may
+end.
+
+Invalid images are named `ebEEEE', where EEEE is the physical index of the
+eraseblock in the image. Valid images are named `ebEEEE_VVV_NNN_RRR' where
+VVV is the known volume ID, NNN is the logical number and RRR is the version
+of the eraseblock data. Note that the version number is in hexadecimal.
+
+Invalid images may also contain this postfix, if the data in the header
+could be valid (ie. the header contains a resonable volume ID, but the
+header and/or data CRCs are not valid). If this is the case, images are named
+`ebEEEE_VVV_NNN_RRR.reason', so as to distinguish known values from
+non\-definite ones.
+
+See \fBREASON SUFFIXES\fR.
+.IP "\-r, \-\-rebuild \fIvolume\-id\fR"
+Specify a volume to rebuild. Can be used successively to specify
+several volumes to be rebuilt.
+
+Images are named `volumeVVV' where VVV is the volume ID. For each missing
+eraseblock, an error message will be printed.
+.IP "\-v, \-\-vol\-split"
+When flagged, images are created for each valid eraseblock in
+\fIimage\-file\fR. Since a vaild eraseblock will have a defined data start and
+data length, only this range will make up the image.
+
+Images are named `volVVV_NNN_RRR_EEEE', where, for the data in the eraseblock,
+VVV is the volume ID, NNN is the logical number, RRR is the version and EEEE
+is the phyisical index of the eraseblock in the image.
+.IP "\-V, \-\-vol\-split!"
+Same as above, only all images are the complete eraseblock (including headers,
+and raw data, even past the point where the data is supposed to end).
+Overrides \-v when both \-v and \-V are flagged.
+.SH ANALYSIS
+The following files will be generated during the analysis:
+.IP "analysis_ec_hdr.data"
+A space delimited table with these two columns for each eraseblock: the
+eraseblock's index or physical position in the image, and the eraseblock's
+erase count. The third column contains the erase count data sorted.
+.IP "analysis_vid_hdr.data"
+A space delimited table with these four colums for each eraseblock: the
+volume ID, the volume logical number, the leb version, and the data size.
+In addition there are a normalized column representing the volume ID and
+volume logical number, a normalized column representing the leb version, and
+a normalized column representing the data_size. These normalized columns are
+used to better draw the the gnuplot image.
+.IP "analysis_ec_hdr.plot"
+A gnuplot script for quickly viewing a sample output from the respective .data
+file.
+.IP "analysis_vid_hdr.plot"
+A gnuplot script for quickly viewing a sample output from the respective .data
+file.
+.SH REASONS SUFFIXES
+When \-\-eb\-split produces possibly invalid, though usable, eraseblocks, the
+known reason suffixes are:
+.IP ".ec_magic"
+The erase counter header did not contain a valid magic field.
+.IP ".ec_hdr_crc"
+The erase counter header did not contain a vaild header CRC field.
+.IP ".vid_magic"
+The volume ID header did not contain a valid magic field.
+.IP ".vid_hdr_crc"
+The volume ID header did not contain a valid header CRC field.
+.IP ".data_crc"
+The volume ID header did not contain a valid data CRC field.
+.SH EXAMPLES
+To extract and rebuild all valid volumes from demo.img (note the output
+directory will be /home/user/unubi_demo.img):
+.sp 1
+.RS
+.B /home/user# unubi demo.img
+.sp 1
+.RE
+To analyze demo.img as well as extract and rebuild volume 7:

+This directory contains a new UBI toolchain which is intended to replace
+the old one. All the utilities start with "ubi-" to distinguish them from
+the old utilities. All support "-h" option which prints sufficient usage
+information. See the MTD web-site for more information.
+
+Motivation for new tool-chain.
+
+I was doing very active UBI development and had to add new features like
+dynamic UBI devices and auto-resize feature. Because of the mess in the
+the old tools I basically could not figure out how to upgrade them. In
+my humble oppinion, they are unmaintainable. The original authors did not
+show enthusiasm when I mailed them and asked to clean-up the tool-chain
+[1]. Thus, I re-implemented them, but I did borrow things from the old
+tool-chain and preserved copyrights and author names.
+
+I really did try to clean-up the old tool chain, but gave up (see git
+history for confirmation). So,
+
+1. I found the source codes very difficult to navigate and read, especially
+   those related to pdd, pfi, and bootenv. Try to do this yourself - they
+   are a puzzle.
+2. I foud the concept of PFI needlesly complecated - PFI file is nothing
+   else but the initial configuration .ini file + the contents of the
+   UBI volumes packed into one file, but with some changes of the .ini file's
+   format. The PFI file format is not very nice and it is difficult to parse,
+   especially because the PFI headers do not tell you data star and end for
+   each data chunk, and you have to do additional parsing.
+
+   So basically, you have .ini file + images, then you transfer this to pfi,
+   which does not add any other information. For .ini you have libraries
+   which may parse them, for pfi - not. Then you have to parse this pfi
+   which adds unneeded and complex code. This all needs lists, hashmaps,
+   and so on - for no reason.
+3. I found the command line options of the utilities to be inconsistent.
+   This is OK when you script your single task and do not touch it anymore.
+   But when you have to use the utilities while developing and testing,
+   It is difficult to remember their inconsistent options.
+4. I found it wrong to add development options to user utilities like
+   "broken update". End users should not see them.
+5. I did not find any consistent style and convention inside which
+   irritated me.
+6. I found it weird to introduce needless "logging infrastructure" instead
+   of just re-directing stdout and stderr to another file.
+7. I found the tool to be rather IBM-setup oriented. For example, the VID
+   header position was hard-coded. Some utilities were just weird, like
+   mkbootenv, which changed some ethernet addresses mentioned in a
+   configuration file.
+8. Finally, it was very difficult to realize what is pfi and pdd, what for,
+   why I need this transiant pfi file when I just want to create an UBI
+   image. There was zero documentation.
+
+And so on.
+

+ *  COPYRIGHT (C) 1986 Gary S. Brown.  You may use this program, or
+ *  code or tables extracted from it, as desired without restriction.
+ *
+ *  First, the polynomial itself and its table of feedback terms.  The
+ *  polynomial is
+ *  X^32+X^26+X^23+X^22+X^16+X^12+X^11+X^10+X^8+X^7+X^5+X^4+X^2+X^1+X^0
+ *
+ *  Note that we take it "backwards" and put the highest-order term in
+ *  the lowest-order bit.  The X^32 term is "implied"; the LSB is the
+ *  X^31 term, etc.  The X^0 term (usually shown as "+1") results in
+ *  the MSB being 1
+ *
+ *  Note that the usual hardware shift register implementation, which
+ *  is what we're using (we're merely optimizing it by doing eight-bit
+ *  chunks at a time) shifts bits into the lowest-order term.  In our
+ *  implementation, that means shifting towards the right.  Why do we
+ *  do it this way?  Because the calculated CRC must be transmitted in
+ *  order from highest-order term to lowest-order term.  UARTs transmit
+ *  characters in order from LSB to MSB.  By storing the CRC this way
+ *  we hand it to the UART in the order low-byte to high-byte; the UART
+ *  sends each low-bit to hight-bit; and the result is transmission bit
+ *  by bit from highest- to lowest-order term without requiring any bit
+ *  shuffling on our part.  Reception works similarly
+ *
+ *  The feedback terms table consists of 256, 32-bit entries.  Notes
+ *
+ *      The table can be generated at runtime if desired; code to do so
+ *      is shown later.  It might not be obvious, but the feedback
+ *      terms simply represent the results of eight shift/xor opera
+ *      tions for all combinations of data and CRC register values
+ *

+There is a problem with udev: when a volume is created, there is a delay
+before corresponding /dev/ubiX_Y device node is created by udev, so some
+tests fail because of this. The symptom is error messages like
+"cannot open /dev/ubi0_0".
+
+One possible solution of this problem is to pre-create UBI device and volume
+nodes. there is even a script which may be used for this in ubi-utils/scripts/.
+But this is not enough because udev will still remove and re-create the nodes
+and tests will still fail. So you need to stop removing device nodes using
+the following udev rule:
+
+	KERNEL=="ubi*_*", ACTION=="remove", OPTIONS+="ignore_device"
+
+In our Ubuntu distribution we put that to new file:
+/etc/udev/rules.d/50-local.rules
+
+Another possibility is to call udevsettle utility in libubi after the volume
+has been created See src/libubi.c - the call is there but is commented out.
+This is anyway an ugly hack, but works, although makes the tests slower.
