Hopefully the last change. I decided to remove all the rev A fixups
from the cuboot-warp file. I am the only person using a rev A, and I
can use the command line to specify any needed partitions. There is
really only one partition needed to boot from nand since u-boot can be
used to flash the image

Hi,
Something in a function signature called "__attribute_used__" would
compile in 2.6.24. This does not compile in 2.6.26. Using the
"store_##NAME" template from arch/powerpc/kernel/sysfs.c as a guide,
this appears to have changed to "__used". Anything work in both?

Add a new linux,drconf-usable-memory property to the device tree. This property
