This need further work on the ppc4xx platforms to get it booting from
flash. As now the dtb is appended to the "normal" U-Boot image. And this
image is fine-tuned to fit into currently 512KiB. With the last word
(reset vector of the ppc4xx) located at 0xffff.fffc. So we need to
include this dtb into the image this way:
0xfff8.0000 U-Boot code / text etc
...
dtb
0xffff.fffc reset vector
Looking for the current options shows that perhaps CONFIG_OF_EMBED seems
to be exactly what we are need. I'll got it working on Canyonlands after
a bit of debugging. I'll post the necessary small patches soon...
Thanks,
Stefan
