Re: Configure tweaks for SystemACE without CONFIG_XILINX_OCP

I'm working on getting sysace to come up on our custom hw.

Where did you put the definitions that the driver code needs, eg:
#if defined(CONFIG_XILINX_SYSACE)
#define XPAR_XSYSACE_NUM_INSTANCES	1
#define XPAR_SYSACE_0_BASEADDR		0xe8100000
#define XPAR_SYSACE_0_HIGHADDR		0xe8100FFF
#define XPAR_SYSACE_0_DEVICE_ID		160
#define XPAR_INTC_0_SYSACE_0_VEC_ID	51  /* UIC1:20, IRQ9 */
#endif

Am I way off base with these?  I dropped them in my board specific
header file...  Or, should I be using:

#define XPAR_SYSACE_0_BASEADDR		0x0000000148100000ULL
#define XPAR_SYSACE_0_HIGHADDR		0x0000000148100FFFULL

First, you'll need the attached sysace-without-virtexii patch, which
has not been pushed to the linuxppc-2.4 tree yet. This fixes some
V2PRO dependencies when XILINX_OCP is activated.


I started by editing the file platforms/xilinx_ocp/xparameters.h:

The CONFIG_JSE is for my board. I then added the xparameters_jse.h
file next to the xparameters_ml300.h that has the pertinent values
for my system. I've attached mine as a working example.


I also edited the arch/ppc/config.in so that the right defines
are enabled:

This activates CONFIG_XILINX_OCP when I config the JSE board,
and that allows the XILINX_SYSACE to be selected. From here,
make sure CONFIG_XILINX_SYSACE=y in your .config and you are
set.
