Linux 2.6 and uboot

[Gary Kenaley]

I found that when trying to build kernel 2.6.19.2 with the ELDK 4.1, and
run it on an MPC8349EMDS with u-boot 1.1.3, I had to use ARCH=ppc.
ARCH=powerpc would immediately hang. The different architectures use
different default kernel configuration files for the same board.

But now I am unable to get USB and MTD to work on the board, and am
wondering if ARC=ppc is still a viable choice on kernels newer than
about 2.6.15, or whether it lacks the best driver support. Could someone
please offer a recommendation on this issue?
