[U-Boot-Users] STX AMC8548 board

Hi Dan,
  Thanks for replying. I got to know the address I'd be looking at to
find the configuration space of RapidIO. (Actually I was looking at
address e00c0000, and that was the correct location of configuration
  In case of STx support it comes very late for me as I am working with
+5.30 GMT.
  The problem I am facing with this is that very few people I find
working on RapidIO of MPC8548. On freescale website as well, there is
very little documentation about how to deal with RapidIO (Regarding
RapidIO packet sending and receiving.)

Have you contacted STx?  I believe they have a
complete Linux Rapid IO kit, that includes an updated
version of u-boot, specifically for this board.  It
could be useful to your progress.

Of course it does.  All of those registers are relative
to the CCSRBAR.

Well, you should probably consider writing some
software to do the necessary Rapid IO initialization
and the testing you desire.  There aren't enough
hours in a week to manually peek/poke all of the
registers necessary to do something useful.  :-)
