[-- Attachment #1: Type: TEXT/PLAIN, Size: 820 bytes --]

Hello,

attached is a patch that adds MTD support for a couple of PowerPC
boards based on the IBM440GP CPU. It also clean up the PPC
section in the mapping drivers Config.in, making it more robust
against configuration errors.

All code was taken directly from linuxppc_2_4_devel, and I didn't
write it. I shall add commandline paritioning support some time soon,
though.

If nobody objects, I will commit it to the repository.

Thanks,
Marius
