Apparently musl doesn't mind and includes this header by default,

df8ca9a5c4 mtd: add -c option for specifying amount of data to be used for checksum
So far fixtrx was calculating checksum over amount of data matching
partition erase size. It was mostly a workaround of checksum problem
after changing anything in initial TRX content (e.g. formatting JFFS2).
Its main purpose was to make bootloader accept modified TRX. This didn't
provide much protection of flash data against corruption.

This new option lets caller request calculating checksum over a bigger
amount of data. It may be used e.g. to include whole kernel data for
checksum and hopefully make bootloader go info failsafe mode if
something goes wrong.

1) Put sanity checks in one place
2) Respect provided offset
3) Read only as much data as needed for MD5 calculation

Thanks to the last change this is a great speedup and memory saver. On
devices with NAND flash we were allocating & reading about 128 MiB while
something about 8 MiB is enough.

4a4c324cd2 mtd: fix reading of image magic bytes in smaller chunks
The image_check currently fails when it cannot read all magic bytes in a
single chunk. But this can happen when the data are read from a pipe. This
currently breaks the openmesh.sh upgrade script with musl because it uses
dd with a blocksize of 1 to copy the image file to the mtd process.

The read can simply be repeated until enough bytes are read for the magic
byte check. It only stops when either an error was returned or 0 bytes were
read.

b5c41ad28c mtd: detect image format when writing
Recently TRX checking code was changed to detect Seama format and don't
abort whole writing operation because of it. This isn't a good long-term
solution. It's a poor idea to teach every format handler recognizing all
possible formats. Instead it should be handled in a generic code which
should run check depending on the detected format.

This will also allow further improvements like fixing formats other than
TRX after replacing JFFS2.

9e233fb241 mtd: add missing <endian.h> include
trx.c in mtd would not include endian.h, so on systems that do not have
this header implicitly included from the other headers (like musl), both
__BYTE_ORDER and __BIG_ENDIAN would be undefined and thus 0, leading to
it always presuming a big-endian system. this would lead to issues when
running mtd fixtrx on little-endian systems, as it would never recognize
the TRX magic as result of the broken STORE32_LE() macro.

c10d97484a Add more license tags with SPDX identifiers
Note, that licensing stuff is a nightmare: many packages does not clearly
state their licenses, and often multiple source files are simply copied
together - each with different licensing information in the file headers.

I tried hard to ensure, that the license information extracted into the OpenWRT's
makefiles fit the "spirit" of the packages, e.g. such small packages which
come without a dedicated source archive "inherites" the OpenWRT's own license
in my opinion.

However, I can not garantee that I always picked the correct information
and/or did not miss license information.

766dff7445 mtd: Fix trx check after partition rename ("linux" to "firmware")
On brcm47xx (Huawei E970), I noticed that sysupgrade now tries to flash trx images which don't fit into the flash, resulting in non-booting system.

I found that mtd does trx size checking only when flashing to a partition called "linux". This patch changes this to be "firmware".

This matches the following patch which changed partition name in bcm47xxpart.c driver to "firmware":

NAND flash is very likely to contain bad blocks.

ff17114ba1 ar71xx: Unifi AP Pro sysupgrade patch
The current implementation of mtd will not append the backup
file created by sysupgrade to the correct partition, as mtd will append
the data to first jffs2 partition it finds. As the kernel is also
stored on a jffs2 partition (which resides before the overlay
partition), the data will be appended to this partition.

To fix this problem, a new option

-s <number>             skip the first n bytes when appending data to the jffs2 partiton, defaults to "0"

is added to mtd.
