Newbie and linux on virtex-II ppc

[schardt]

Okay, im really blind i think, so i started again :

- 2.6.22 kernel from kernel.org
- cp /arch/ppc/configs/ml300_defconfig .config
- edit Makefile to use ARCH=ppc and CROSS_COMPILE=powerpc-405-linux-gnu-
- copy xparams
- make menuconfig -> no SYSACE blockdevice :((( *aaaaargh*

i will try the grant kernel now :)
