[meta-xilinx] Linux/bare-metal AMP interrupt routing

[Edward Wingate]

I got a bare-metal application running on CPU1 with Linux on CPU0,
using zynq_remoteproc as described in ug978.

One thing I don't understand in ug978
(http://www.xilinx.com/support/documentation/sw_manuals/petalinux2014_2/ug978-petalinux-zynq-amp.pdf)
is the interrupts property in the remoteproc device tree entry, pg.
23:

test: remoteproc-test at 0 {
    compatible = "xlnx,zynq, remoteproc";
    reg = < 0x0 0x10000000 >;
    interrupt-parent = <&ps7_scugic_0>;
    interrupts = < 0 37 4 0 38 4 >;
    firmware = "freertos";
    ipino = <6>;
    vring0 = <2>;
    vring1 = <3>;
} ;

It says "The interrupts property allows the consumption of interrupts
from Linux to be routed for FreeRTOS, in this case the TTC1 interrupts
are routed."  But 37 and 38 are XPS_PMU0_INT_ID and XPS_PMU1_INT_ID,
the performance monitoring units, not TTC1.  What am I missing here?

I want to route FPGA2 interrupt (63) instead, so I have < 0 63 4 > for
interrupts property, but it doesn't seem to be working.  I set up the
interrupt handler on my CPU1 bare-metal application for
XPS_FPGA2_INT_ID, but it doesn't trigger.  Are there other config
items I need to change?

Thanks for your help.
