Hi Sascha,
sorry for responding this late, but we are still getting the same errors
as before when using bareboximd with these three patches.
Are you sure we can revert this patch? The file can still be opened in
bareboximd with mmap(), and then be written with this write_file(),
which fails with the same error:
Cannot write to barebox.bin: Bad address
CRC: write crc token to barebox.bin failed: -14
Bad address
Best regards,
Andrej

mmap() is no longer used in read_file_2(), so this patch is no longer
necessary.
This reverts commit 738601e1258c55953284ee10801b26b9977918c2.
