I worked out of the 2.4 _devel rsync tree (2.4.20-rc2) as I wasn't able to get my bitkeeper snapshot to compile for walnut. High level view of the changes: config.in changes to set a cpu type of 405pm, FPU unavailable exception, load_up_fpu(), giveup_fpu(), additions to the ibm ethernet code to support the multiplexed mal ints on the 405pm, bits & pieces to tie it all together, and a hack or 2 which ought to be reworked. Missing: no PCI, DMA or IDE support yet. send me email if The Powers That Be want this stuff. It has been stress tested with a mix of fpu tasks and handling a ping flood.
