Re: Best kernel for Xilinx VirtexII Pro/PPC405 ?

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

Good to hear that you got everything working. Just as a note: XAPP542 
(http://direct.xilinx.com/bvdocs/appnotes/xapp542.pdf) contains a patch 
for the Linux kernel to make it work together with U-Boot.

Does linuxppc-2.4 still accept patches?
