In 54d68799, mtd->eb_cnt was enforced to be '1' if MTD_NO_ERASE is set.
This was done with the aim of preventing divisions by zero.
However, even if MTD_NO_ERASE is set, mtd->eb_size (eraseblock size) can
still be set to a non-zero value which would not cause a division by
zero.
Instead, enforcing an eraseblock count of '1' here even leads to
inconsistent eraseblock counting in mtd-utils and lets for example a
'flash_erase' on an mtdnand device fail:
| # flash_erase /dev/mtd0 0 0
| Erasing 32768 Kibyte @ 0 -- 0 % complete libmtd: error!: bad eraseblock number 255, mtd0 has 1 eraseblocks
| flash_erase: error!: /dev/mtd0: MTD Erase entire chip failureTrying one by one each sector.
| error 22 (Invalid argument)
| Erasing 128 Kibyte @ 0 -- 0 % complete libmtd: error!: bad eraseblock number 1, mtd0 has 1 eraseblocks
| flash_erase: error!: /dev/mtd0: MTD get bad block failed
| error 22 (Invalid argument)
Also mtdinfo would look inconsistent (eraseblock size vs amount):
| # mtdinfo /dev/mtd0
| mtd0
| Name: mtdram test device
| Type: ram
| Eraseblock size: 131072 bytes, 128.0 KiB
| Amount of eraseblocks: 1 (33554432 bytes, 32.0 MiB)
| Minimum input/output unit size: 1 byte
| Sub-page size: 1 byte
| Character device major/minor: 90:0
| Bad blocks are allowed: false
| Device is writable: true
Fix this by enforcing mtd->eb_cnt to be '1' only when mtd->eb_size is
actually zero and would lead to a division by zero otherwise.

When writing a full 4GiB NAND to a file end_addr becomes 0x100000000.
With that writing out the first page to the file doesn't happen
because size_left is calculated to 0x100000000 - 0 = 0x100000000
which is then truncated to 32bit and becomes zero. Fix this by
using an appropriate 64bit type for size_left.

In commit a888044525, various header files that were added to the
distribution tarball via EXTRA_DIST were instead added to the source
lists of their respective programs instead.
In the case of jffsX-utils, a missing escape for a new-line in the
source list caused the include/linux/jffs2.h header to not be packged
in the release tarball. This went undiscovered, as the system on which
the release tarball was built, had the same header installed installed
in the system include directory, so a `make distcheck` succeeded.

The speed test does reads and writes of different sizes:
- eraseblock
- page
- two pages
At least this is the theory because, as opposed to the legacy kernel
module doing the same measurement, the userspace tool uses the subpage
size (hence accessing the same page 4, 8 or 16 times depending on the
subpage setting). Of course if the controller does not support subpages,
this issue is not visible.
Use mtd.min_io_size instead for non-NOR devices in order to get the
right bandwidth (at least one that fits the logs).

Adding AC_SYS_LARGEFILE results in _FILE_OFFSET_BITS being defined to 64

The "need_getrandom" check and result is used only for the "ubihealthd".
This tool is very important to have it around at run-time, while the
corresponding "mkfs.ubifs" tool is still optional (think about offline
generated ubifs images).
Since compiling "mkfs.ubifs" adds more dependencies (various shared
libraries), buildsystems for embedded devices will add these shared
libraries to the root filesystem even if "mkfs.ubifs" isn't used or
installed.
Thus, handling both tools independently makes sense. The previous behavior
is kept, e.g. if UBIFS support is enabled, it enables "ubihealthd" as well.

The nandflipbits tool is intended to be used when one need to flip one or
several specific bits on a NAND media.
It can be useful to manually recover from an unexpected bit flip on a flash
device, though the main purpose of this tool is to provide a way to test
ECC algorithms robustness.
One typical example I used this tool for is testing HW ECC engines behavior
when bitflips occur in an erased page: most HW engines do not correctly
handle this case, because, most of the time, ECC bits generated for an
empty page are not all 1s, and, empty page detection embedded in such
engines is only validating that all bits are set to 1s (which is not true
when a bit-flip has occurred).
Another use of this tool is replacing nandbiterrs test which
absolutely do not work with MLC-like chips because of the rewriting of
the pages in raw mode to toggle ones into zeroes.

The function reads file data into a buffer and then checks if we
actually are at the end-of-file by trying to read one more byte.
For whatever reason, the code uses an int instead of a char. It's
not pretty but works. But again, this is something that every
static analysis tool barks at.
Further more, the error messages are inverted. "We aren't at EOF yet"
is printed on failure and something like "read error %m" is printed
on success.

Many tools open a file descriptor, close it a the end and have some

In some cases, if opening the file fails the error path is taken and

technically not a real issue but something that pretty much any static
