So the easiest thing is to just add another xparameters_xxxx.h and have it conditionally included into the arch/ppc/platforms/xilinx_ocp/xparameters.h file. Put your board specific information in that file and you should be fine from there. You might have to also munge the config.in files and/or Makefiles to make sure everything gets included that needs to be there to support the SystemACE. Incidentally, I would be interested in hearing what kind of transfer rates people are seeing using the SystemACE. I have run some Bonnie tests on the filesystem on my MPC8266 board and it is pretty slow. Jeff Angielski The PTR Group ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
