The SystemACE driver is currently written as a subset of the
CONFIG_XILINX_OCP code. 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.
