[U-Boot-Users] Wind River SBC8560 saga continues

The more I dig into my problem, the more confused I get.

Here is the latest plot twist...

Looking at the sources for the memory configuration:


I notice the TLB entries seem to be set up to do a simple straight
mapping from the effective address to the real address.  No problem
so far.

Looking further, I notice the addresses used for the chip select
values do not match the addresses specified in the SBC8560 board
engineering specifications.  Now it is getting a little confusing.

Finally, I notice there is one area of memory, defined at 0x70000000,
which has a TLB but does not appear to have any real memory to back
it up.  (This address is associated with the CFG_INIT_RAM_ADDR
defined symbol.)

I am hoping someone might be able to point out if I am missing
something (subtle or obvious :-).

I had thought this might be the source of the CPM SCC problem I
am having, but so far it does not seem to be the case.

Thanks in advance.
