Now that I have 10-STABLE working from eMMC, I decided to take a look
at the 1Ghz patches.

I started out with uboot_beaglebone_eabi_port, but although I was able
to get it to build (after removing the 0 length patch files), I
couldn't seem to get crotchet-freebsd to pick it up.  It seems that
the `uboot_eabi_port` tools is missing; I'm using pkgng, so maybe
that's the problem.

I noticed that uboot_beaglebone_eabi_port with the 1Ghz patches builds
against u-boot-2014.01 so I downloaded u-boot-2014.01.tar.bz2,
unpacked it in the crotchet-freebsd directory and replaced the patches
in crotchet-freebsd/boards/BeagleBone/files with the 1Ghz ones and
tried a crotchet build. This failed to link with:

armv6-freebsd-ld: region .sram is full (u-boot-spl section .data)
armv6-freebsd-ld: region .sram is full (u-boot-spl section .data)
armv6-freebsd-ld: section .u_boot_list [00000000402f0400 ->
00000000402f0477] overlaps section .text [00000000402f0400 ->
000000004030657b]
armv6-freebsd-ld: u-boot-spl: section .text lma 0x402f0400 overlaps
previous sections
armv6-freebsd-ld: u-boot-spl: section .rodata lma 0x4030657c overlaps
previous sections
armv6-freebsd-ld: u-boot-spl: section .data lma 0x4030aec8 overlaps
previous sections


So no luck there.  I did try also building Patrick Kelsey's fork of
u-boot which failed with very similar errors:

armv6-freebsd-ld: region .sram is full (u-boot-spl section .rodata)
armv6-freebsd-ld: region .sram is full (u-boot-spl section .rodata)
armv6-freebsd-ld: section .data [00000000402f0400 -> 00000000402f1141]
overlaps section .text [00000000402f0400 -> 0000000040307257]
armv6-freebsd-ld: u-boot-spl: section .text lma 0x402f0400 overlaps
previous sections
armv6-freebsd-ld: u-boot-spl: section .u_boot_list lma 0x402f1144
overlaps previous sections


I did notice that the *original* patches for
uboot_beaglebone_eabi_port seem to remove api_net.c from the build,
perhaps this was an effort to slim down the binary to avoid this issue
(however, the 1Ghz patches nuke the patches that removed api_net.c and
it's callers).

Finally, I took a look at the patches to see if I could rework them
for u-boot-2014.04 (since it was recently released), but it seems that
there have been significant changes since 2013.04 so I need to learn
more about u-boot before going near that!

Thanks,
