You can choose between an arch/ppc or an arch/powerpc kernel (arch/ppc the old 32 bit support; and it is steadly being migrated over to arch/powerpc). If you want to stick with arch/ppc; you can use any recent 2.6 kernel and search the mailing list for the patches adding bestcomm, ethernet and IDE support. If you want to use an arch/powerpc kernel, look at my tree on http://git.secretlab.ca. The lite5200 branch already contains IDE, bestcomm, ethernet, PCI, etc. > Unfortunately my tests tell me none of the listed kernels works out of > the box for the target: the former being not officially supported by > DENX for the Lite5200 target, the latter having a Lite5200/Lite5200B > configuration target. My tree works for me; but you'll need to update to a recent u-boot. arch/powerpc requires passing in a flattened device tree at boot time. Look in arch/powerpc/boot/dts/lite5200b.dts for the device tree source. You'll also need to get the device tree compiler from www.jdl.org. Plus since Sylvain and I are actively working on this stuff; there's a better chance that we can help. :) cheers, g. -- Grant Likely, B.Sc. P.Eng.
