One thing the README doesn't appear to touch on in the section describing it (I'm sure it does somewhere else it's 3500 lines of it's 'correctness') is that when using data cache for CFG_INIT_RAM_ADDR, then CFG_INIT_RAM_ADDR doesn't end up pointing to anything real (but there is a BAT covering it (MPC82xx), and with caching turned on) in which case provided that you never exceed the size of the locked part of cache, nothing ever ends up going out to the local bus, and that makes pseudo-ram.

Although it sounds like 0xE6000000 would be an address normally assigned to the CPM, in which case the CFG_INIT_RAM_ADDR part of the README is valid, but maybe not???

Hi, In the uboot code for a MPC8360- based evaluation board, the initial RAM address (CFG_INIT_RAM_ADDR) is set to 0xE6000000. But, this address is not mapped to any device nor to the Internal config. registers in the board memory map.

If I need to port uboot , how do I decide what address to use for the CFG_INIT_RAM_ADDR?

Thanks and Regards, Ananth.
