I think you have the wrong end of the stick. Our boards have 32MB of RAM located at 0. We have placed IMMR at 0xfa200000. The address of 0xc0000000 is a virtual address it does not have to have any relation to a physical address this is done by the memory manager. The only constant is that the boot flash MUST be connected to chip select 0. Everything else is mostly software configurable.

I know RAM has to be at 0xc0000000 and immr at 0xff000000 ... is there any rule of thumb for anything else? Jim ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
