- Measure when the read operation ends.

| flash_erase: error!: /dev/mtd0: MTD get bad block failed

misc-utils: flashcp: Add new function that copy only different blocks
- The original flashcp process is erase, write and verify all blocks
in one time from file to device.
This patch will add a function that only copy different block data
from file to device. The function will compare blocks by block
between file and device, then erase and write block data from file
to device if found different block.

Some flash types support full erase chip command which can reduce the
flash erase time. Try first to erase the entire flash and fall back
to the old method if the operation fails.

Currently mtd-utils on 32bit systems fail on devices >2GiB due to off_t being

Adding AC_SYS_LARGEFILE results in _FILE_OFFSET_BITS being defined to 64

mtd-utils: ubihealthd: this tool does not depend on UBIFS
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.

Add an ubifs mount helper
This abstracts away attaching of the right ubi and then selecting the right
ubi device and volume to mount.
As described in the comment at the top this allows to mount ubifs volumes
directly from /etc/fstab without having to use hardcoded numbers (which
depend on mount order and so are unreliable) and extra magic to care for

mtd-utils: Add nandflipbits tool
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.

First, there is no option named of X509_OPTION. It was presumably

Similarly, '}' got moved into the WITH_CRYPTO branch, but not into
else branch, resulting in tons of errors if fscrypt is disabled.

mtd-utils: Fix "are we really at EOF" test logic in libubi read_data
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.
