I am testing an IceCube/MPC5200 motherboard together with a Diamond Stealth ATI Radeon 9200SE PCI card.
Are you sure that this card works at all in a PowerPC environment?
Attempting to access BAR0 (memory region), results in a 'bus fault'.
This may be an indication that your card requires some "BIOS" initialization code to be run.
Are there further configuration commands that must be executed to access the BAR0 memory region?
Many graphic cards come with their own BIOS code that must be executed to initialize the card. I have no idea if this is the case for the 9200SE, but I would not be surprised either. Without such initialization it is likely that the memory on the card remains uninitialized and thus unaccessable.
The only way to make such cards work is by enabling the BIOS emulator (see board/MAI/bios_emulator directory) and use this to run the init code of your card.
Good luck!!
Alternately, is there a source of information that I can read to learn how to set up PCI so that my standalone application can use it?
Read the U-Boot and the Linux kernel source code and associated documentation.
