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...

Hello,

When using the SGDMA to test the ACP port, and also the SDRAM controller, what is the maximum frequency you could use in order to get the SGDMA system working? You said in a previous post that you used 150 MHz, is is possible to use something greater than that?

Thanks.
