The current version of struct stat has been taken from an
ancient Linux Kernel. It looks different on different architectures
to support different userspace formats of struct stat. As we do
not have a userspace on barebox there is no need to keep different
versions.
Also, this unification make MIPS arch possible.

While getting rid of all the format(barebox_printf) warnings was nice,
it caused the printf calls in arch/sandbox/os/common.c to get directed
to the barebox versions rather than the libc ones causing a crash:
E.G. before this revert:
nm -a barebox|grep -w printf
0000000000404fa3 T print
And after:
nm -a barebox|grep -w printf
U printf@@GLIBC_2.2.5

This reverts commit 6b082cfe9f.
The following patch came across the mtd mailing list today. I thinks its also
valid for barebox (it handles a special corner case, but maybe it can hit us,
too):
In nand_do_write_ops() code it is possible for a caller to provide
ops.oobbuf populated and ops.mode == MTD_OOB_AUTO, which currently
means that the chip->oob_poi buffer isn't initialised to all 0xFF.
The nand_fill_oob() method then carries out the task of copying
the provided OOB data to oob_poi, but with MTD_OOB_AUTO it skips
areas marked as unavailable by the layout struct, including the
bad block marker bytes.
An example of this causing issues is when the last OOB data read
was from the start of a bad block where the markers are not 0xFF,
and the caller wishes to write new OOB data at the beginning of
another block. In this scenario the caller would provide OOB data,
but nand_fill_oob() would skip the bad block marker bytes in
oob_poi before copying the OOB data provided by the caller.
This means that when the OOB data is written back to NAND,
the block is inadvertently marked as bad without the caller knowing.
This has been witnessed when using YAFFS2 where tags are stored
in the OOB.
This patch changes the code so that oob_poi is always initialised
to 0xFF to make sure no left over data is inadvertently written
back to OOB data.
The comment above is for the linux kernel, but the same is valid for barebox
and CPUs writing the OOB date controlled in software (like the Samsung
S3C2440 does).

Hi
When setting the default env of barebox to a svn directory the build stops

The interface emulates the Linux commands, except that you can
specify a sub area - E.G.:
barebox:/ md5sum /dev/fd0 2M+1M /env/config /env/bin/boot 10+2

908b84bcbadd2f263583a65ff31d1cad /env/config 0x00000000 ... 0x000003a7
f23bd15825cc5006cf5f9fd486d82d2d /env/bin/boot 0x0000000a ... 0x0000000c
