100 bytes from the binary with silly tricks. Hope to get this small
enough to run on the models that have 4k SRAM. We are close compiled
for the at91rm9200, but still need to trim for the target.
The NAND Flash environment consists of several distinct components:
- NAND framework (drivers harness for NAND controllers and NAND chips)
- NAND simulator (NANDsim)
- NAND file system (NAND FS)
- Companion tools and utilities
- Documentation (manual pages)
This work is still experimental. Please use with caution.

# This doesn't implement the full Linux boot ABI for arm yet.
# since there's no ATAGs list passed in for r2, and r0 has
# boot options rather than 0 as specified in the standard.
# Commited code to the tree won't touch any of this anyway, but
# future code may be able to use this.
If I interpret the C standard correctly, the storage specifier should be
placed before the inline keyword. While at it, replace __inline by
inline in the files affected.
o This is disabled by default for now, and can be enabled using WITH_FDT at
build time.
o Tested with ARM and PowerPC.

- Only non-sliced bsdlabel style partitioning is currently supported (but provisions
are made towards GPT support, which should follow soon)
- Enable storage support in loader on ARM

This uses the common U-Boot support lib (sys/boot/uboot, already used on
FreeBSD/powerpc), and assumes the underlying firmware has the modern API for
stand-alone apps enabled in the config (CONFIG_API).
Only netbooting is supported at the moment.

bring in FIXUP_BOOT_DRV functionality as an #ifdef. This is not
enabled at this time, and the md5 remains constant with this change.
Apart from the 'accept any partitioning scheme on the device' changes,
this was the biggest delta...
# and yes, we'll merge these into one source file if we can do that in a
# way that makes sense.

code. Added a copyright for the work I did to this file a couple of
years ago. Add John's copyright too, since I'm sure I'll be pulling
more into this code. This also implements a new -n option to not
allow breaking into the boot sequence which was original in the patch
John posted (not in the original i386 code I based this boot2.c on,
only the name is the same). I haven't checked to see if he did that,
or if it was one of Sam's improvements.

- It is opt-out for now so as to give it maximum testing, but it may be
turned opt-in for stable branches depending on the consensus. You
can turn it off with WITHOUT_SSP.
- WITHOUT_SSP was previously used to disable the build of GNU libssp.
It is harmless to steal the knob as SSP symbols have been provided
by libc for a long time, GNU libssp should not have been much used.
- SSP is disabled in a few corners such as system bootstrap programs
(sys/boot), process bootstrap code (rtld, csu) and SSP symbols themselves.
- It should be safe to use -fstack-protector-all to build world, however
libc will be automatically downgraded to -fstack-protector because it
breaks rtld otherwise.
- This option is unavailable on ia64.
Enable GCC stack protection (aka Propolice) for kernel:
- It is opt-out for now so as to give it maximum testing.
- Do not compile your kernel with -fstack-protector-all, it won't work.

wants to use rather than forcing ufsread.c to have that knowledge.

order. The kernel used to shuffle them around to get things right,
but that was recently fixed. This makes our boot loader match the
behavior of most other boot loaders for the atmel parts. This bug was
inherited from the Kwikbyte loader that we started from.
This bug was discovered by Bj.ANvrn KNvnig back in June, but fell on the
floor. He provided patches to the kernel, include backwards
compatibility options that were similar to Olivier's if_ate.c commit.
