- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

Use 32-bit ufs_ino_t instead of ino_t to keep boot2 small and prevent
unnecessary 64-bit math on 32-bit machines.

Add support for passing in the board ID.

# 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.

Look for /boot/config in addition to /boot.config, with the former taking
precedence over the latter if it exists.

More diff reductions against ixp425/boot2/boot2.c. This time, we
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.

Bring in the trivial differences between this code and John Hay's new
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.

Remove XMODEM_DL support. It never was complete and only serves to
increase the diffs with other arm boot2 loaders.

Indent with 8-space tabs. This reduces the diffs to the newer ixp425
boot2 and may make it easier to merge these files in the future...

Use the smaller cgbase() macro in ufsread.c if UFS_SMALL_CGBASE is
defined. This lets each boot program choose which version of cgbase() it
wants to use rather than forcing ufsread.c to have that knowledge.

Don't pass RB_BOOTINFO to the kernel. There's no bootinfo actually
passed into the kernel, and the kernel will soon grow that ability on
arm.

MFp4:
Add support for the CENTIPAD board (http://www.harerod.de/centipad/index.html)
(which is a very cool, very small ARM board)
Add support for KB9202B (it has different memory)
Make BOOT_FLAVOR settable
Minor cleanup nits

Loop on sdcard init. This helps if one hasn't plugged in the card
fast enough, or there's other issues that cause the first try to fail.

Various buglets fixed (from submitter):

The changes to getstr() is so that the character that is
passed in to it, is also processed just as the rest. I also
removed one of the getc() calls otherwise you loose every
second character.

I also changed the strcpy of kname, so that it only happens if
kname is '\0'. This is so that one can pass a kernel in
through /boot.config.

The last change to boot2.c is in parse(). If you tried to type
a kernel name to boot, the first character was lost, the arg--
fix that.

Mfp4: We no longer need ee.h included here.

MFp4: Make boot2 work on Kwikbyte KB9202 boards.

MFp4:

Massive update. The highlights:
o dramatically cut memory usage by writing better, less intertwingled
code.
o implement booting off mmc/sd cards (sd only tested one at the moment)
o start to split out board specific stuff for boot2.
