The documentation of libmtd_open says, if it returns NULL and errno is
zero, MTD is not present. However, the current version always returns
a libmtd_t object. The function internally checks, if it can access the
MTD sysfs files and, if not, sets a flag to use the procfs fallback.
This patch adds an additional check to libmtd_open, to test if the
MTD procfs file can be read and fails with errno cleared if it does
not exist.
Furhtermore, mtd_get_info is documented to fail with errno set to ENODEV
if MTD is not present. First of all, this was broken in the original
version. It was implemented to specification for the sysfs code path,
but if MTD is not present, that won't be executed, because of the flag
set by libmtd_open. This makes the check not only redundant, but masks
an actual error (the sysfs paths suddenly not being readable anymore).
The legacy path that was used if the sysfs files are not avaible fails
with ENOENT if it cannot read the procfs file. With the above changes
in addition, we don't have a libmtd_t object if neither sysfs nor
procfs is readable, so this error status no longer makes sense.
This patch removes the documentation on the ENODEV errno, and
makes sure that mtd_get_info always returns with apropriate errno
on failure.

This is based on the patch from Khem Raj used by openembedded. In
addition to the original patch, this also removes the fallback
implementation that was provided for C libraries that don't implement
rpmatch.

"flash_erase" fails on nand flash with JFFS2 that has OOB size greater than
32 bytes. "flash_erase" uses "MEMGETOOSEL" to determine OOB size. This ioctl
call is obsolete and returns error if OOB size is more than 32 bytes.
This patch fixes this issue by using "mtd_write" to update clean-marker
instead of mtd_oob_write. This fix is based on the discussion:

rand() is not thread safe, but glibc seems to use a shared state which is
protected by a mutex. io_paral spawns a few threads and they call rand()
more or less in parallel, which causes heavy lock contention. That
makes the test extremely slow on some setups.

UDEV_SETTLE_HACK addresses a problem which does no longer exist on Linux.
These days we have devtmpfs. New devices will automatically created on
the kernel side and user space has no longer to wait for udev.
As udev has a hard dependency on devtmpfs we can depend on it too.
People which don't use udev nor plain devtmpfs are anyways on their own.
Android, I'm looking at you...

On 32bit systems (e.g. ARM) the size of off_t can be 4 byte and the size of loff_t 8 byte.
This causes compiler warnings like the following:
flash_erase.c: In function 'show_progress':
flash_erase.c:56:22: warning: format '%llx' expects argument of type 'long long unsigned int', but argument 3 has type 'off_t {aka long int}' [-Wformat=]
bareverbose(!quiet, "\rErasing %d Kibyte @ %"PRIxoff_t" -- %2i %% complete ",
and an output like this:
~# flash_erase /dev/mtd2 0 1
Erasing 64 Kibyte @ 6400000000 -- 0 % complete
~#
Since the size of off_t and loff_t can differ from each other, the
printf format specifier should be determined separately for both.
Further the format specifiers should be based directly on the size of the
particular data type.

The --skip-bad-blocks-to-start option will increase the start address by

JFFS2 supports clustering erase blocks to virtual erase blocks.

For some applications, like building a root filesystem for an embedded
device, it may be desireable to only build and install a subset of the
mtd-utils. This can be done throught the targets of the generated
Makefile and hand picking executables, however the jffsX and ubifs
utilities have external build dependencies that may not be needed.
This patch adds configure switches to disable building the jffsX and
ubifs utilities. Their respective build dependencies (zlib, lzo, uuid)
are only requested if the tools are being built.

Previously, the unit test sysfs mock files and headers were not
added to the distribution packag. Not packaging the header leads
to compilation of the unit tests failing. Not packaging the stub
files caueses the unit tests themselves to fail.
This patch explicitly adds the header and sysfs mock files to the
distribution target, allowing the unit tests to be used outside
the git tree.

Compiling for x86_64 generates a lot of warning because the PRIxoff_t and
PRIdoff_t are not properly defined, which comes from the missing
SIZEOF_LONG definition.
Use the autotools to generate a config.h header, include this header from
common.h and ask autoheader to generate the SIZEOF_LONG and SIZEOF_LOFF_T
definitions.
Use these new definitions to assign the proper descriptors to PRIxoff_t
and PRIdoff_t.

The programs mkfs.jffs2 and mkfs.ubifs include those two headers if
WITHOUT_XATTR is not defined. Up to now, this macro is only defined
if the configure script is run with --without-xattr. If the headers
are not present on a system and the configure script is run without
special flags set, the build fails.
This patch adds a check for the presence of those headers and disables
the feature if one of the headers is missing.

Historically, the mtd-utils and ubi-utils were seperate packages. The
ubi-utils were at some point merged into the mtd-utils. They first
appeared in the release tar-ball in version 1.1.0 in their own
sub-hirarchy with their own buildsystem, readme, documentation, etc.
A lot of the duplicated stuff got centralized/removed over time.
This patch further cleans up the directory hirarchy duplication by
moving common libraries from the ubi-utils/ into the central lib/
and include/ directories in the top directory of the mtd-utils package.
This includes:
- libuib.a & libubigen.a used by the ubi utilities
- libscan.a currently only used by ubiformat
- libiniparser.a used by ubinize

This patch moves the remaining 3 functions from ubiutils-common.{c,h}
into libmtd common.{c,h}.
The functions are only generic utility functions that other mtd-utils
programs may also find usefull and every program that uses libubi links
against libmtd anyway so there is no real reason for keeping around a
seperate ubiutils-common with only generic helper functions.
