ATI Radeon M6-C16h for PPC 440GX

[Roberto Pavon Sierra]

Hello,

i´m using on my custom board with PPC 440GX a ATI M6 Mobility Radeon with
kernel 2.6.12.
Now i have to initialize the ati and configure the kernel to support it.
I don´t have the BIOS of ATI for PPC and i like to simulate this BIOS with
U-boot. How can i configure the U-boot for ATI to initialize or how can i
write the programm for ATI- EEPROM BIOS?
must i install a XF86-Simulator on my board?
