Hello,
i´m using on my custom board a ATI M6 Mobility Radeon with kernel 2.6.12.
Now i have to initialize the ati and configure the kernel to support it. Did
someone use this combination (ppc + ati radeon)? It would be appreciating to
get some help or tipps in configuring to get the ati functioning. Especially
the BIOS of the ATI chip, because i have actually found only x86 binaries.
Is it also possible to set up the bios settings for the ati chip without an
bios eeprom attached via the radeon driver?
Thanks for any help,
David

There is a x86 emulator that can execute x86 VGA BIOS code to initialize
your VGA core in U-Boot. It's part of the MAI port so you can look at
that code and port it to your board. It is actually some scitechsoft
code that's been ported to build within U-Boot.
Gabriel Paubert's preploader code also has an x86 real mode emulator
written in PPC assembly that does the same thing, but it may be more
convenient to work with the stuff in U-Boot. It doesn't help that I
can seem to find a current link to the preploader code. Maybe Gabriel
can appear and provide it.

If you use U-Boot as boot loader you can enable and use the x86
emulator taht comes included with it. But don't expect to much help
with that - except for the Amiga One (where I was told this is
working) I don't know of any other board using this feature.
Best regards,
