[SLOF] [PATCH slof 0/7] sloffs: tool to read and write SLOF images

[Alexey Kardashevskiy]

Here is a rework of "sloffs: tool to read and write SLOF images"
from Andreas.

Changes:
1. reordered patches to have the existing code rework first
2. squashed compiler warning fixes to where the warnings were introduced
3. moved unrelated changes to where they belong to reduce changing
the same lines over again in this patchset

I am still thinking of squashing 4..7 into 3, will this make the patchset
any better?

I did not add "big fat comment" about "char date[6]" in "struct stH"
as I do not know what to comment precisely and whether it is really needed.

Please comment. Thanks.


This is the original cover letter.

This brings the sloffs code to read, copy and append files to an existing
boot_rom.bin from my repository at https://lisas.de/~adrian/slof/slof.git/ .

This code was written in 2008 and all patches have been cherry-picked
without modifications. Only the last patch (13/13) updates the code
to work with today's compilers.

I was able to test that the code still does what it is supposed to do:

$ ./sloffs -l ../boot_rom.bin
