>>I'm not sure what sub-arch we are talking about, but some do have the MMU on.
I am using PPC 870 and u-boot 1.1.2. Which architecture should I look for as a reference example. On my system, the RAM is not at address 0x0 but at 0x10000000. Since the exception table does not take full 32 bit address, I am not sure how to tell the processor about the relocated location. On this custom board with 870, is it necessary to have RAM at address 0x0 (or shadow it) or the 870 supports configuration for different base addresses for memory. Thanks, Atul
