Best kernel for Xilinx VirtexII Pro/PPC405 ?

Hi Peter -
Well, the good news is that it works, and works well. In my humble
opinion, supporting it would be pretty simple, but I completely understand
why RHEL is the supported distribution. I would much rather see effort
put into polishing up EDK under Linux than in supporting every Linux
distro out there.
For me, the bottom line was this: do I want to migrate all of other
development activities from FC4 to RHEL for the sake of EDK, or try to run
EDK under FC4? I tried the latter approach, and now that the Jungo
WinDriver v7.1 is out, parallel port debugging works by simply using
WinDriver 7.1 and patching the Xilinx XPC4 parport driver.
I now have the kernel booting on a Memec 2VP50 eval board using U-Boot as
the bootloader. I used the linuxppc-2.4 kernel rsynced from MontaVista.
That particular kernel did not have support for U-Boot but it did support
the ML300 and a Memec 2VP40/2VP70 board. I had to modify the kernel to
accept a board description structure from U-Boot and I added a new board
type for my custom hardware.
The approach I took was definitely the "roll your own approach", but then
again I've done this (Linux board ports) a couple times and I know U-Boot
well.
