This is likely what Arnd was referring to in his comment on cbe-oss-dev last
week. The "ppe-mmio" node should already exist in the device-tree, and will
have the necessary register map offset and length, so you don't need add the
BP_BASE_OFFSET_PPE_MMIO_REGS definition . This works on the IBM Cell Blades.
To see if it should work on your platform, check for the
directory /proc/device-tree/[EMAIL PROTECTED]/[EMAIL PROTECTED] If that exists,
it should work for your system as well.
Thanks,
