Re: linux 2.4 on ml403

[Peter Ryser <peter.ryser@xilinx.com>]

Jean-Francois,

follow the instructions in the ML403 Reference Design Users Guide (pg 
39). In particular, create the board support package with the Linux MLD 
and use the patch_linux script in the linux sub-directory of the ML403 
reference design. The patch sets bits 1 and 3 in CCR0 which is required 
for ES silicon, i.e. silicon where the PPC405 has a PVR of 0x20011430. 
After applying the patch the problem will be gone.
