ACP port under Linux

Hi, Is there any trick to using the ACP port from FPGA under Linux (3.9)? I'm setting the f2h AR & AW CACHE/PROT/USER by hand, post-qsys, but don't see any indication that the SCU cares at all...

Hi, do you know a way to allocate 64MB of contiguous RAM to a device driver on Linux? I was using the alloc_pages but it only allowed me to allocate 4MB.

Thanks.
