Finally got time to play a bit with this. On the snow/peach boards the
approach is to put u-boot in a legacy u-boot image (not a FIT image),
which has the nice side-effect of re-locating u-boot before jumping to
it.
Unfortunately the depthcharge on the nyan boards appears not to support
legacy images, only FIT images, which don't get relocated before jumping
into the kernel blob. Long story short, on the nyan boards the FIT image
gets loaded at 0x81000000 and the FIT images i created put the u-boot
blob at an offset of 0xCC. After re-configuring CONFIG_SYS_TEXT_BASE to
match i got u-boot starting \o/ ;)
Unfortunately the board seems to hard hang when it tries to enable/use
the data cache. Enabling CONFIG_SYS_DCACHE_OFF makes it get to the
u-boot prompt. Unfortunately neither MMC (didn't detect card) nor USB
(failed to get descriptor from my usb network dongle) worked so i
couldn't try booting a kernel just, but it's start.
Simon, does data cache/MMC/USB work properly when booting u-boot
"natively" rather then chainloading from coreboot or does it have
similar issues?
Fwiw, I've attached the output of u-boot running onthe board (with
CONFIG_SYS_DCACHE_OFF enabled).
