Fix mailbox interrupt

cf4aa62027 Fix mailbox interrupt 
Use IRQ_F2P for interrupts, this is what other designs seem to do.
Use interrupt pin 11 (maps to IRQ=87 devicetree-IRQ=55 (87-32)).

Disable CORE0_FIQ_INTR as we no longer use it.

Add concat ip, apparently needed:
http://www.xilinx.com/support/answers/58942.html

Add constant_zero, and constant_one outputs to parallella_base module.

Tie all unused (by PL) interrupts on the F2P port to 0.

Add burst test
 2016-01-20 07:50:56 -05:00

a4e7ebe47b Add burst test 
Add test for writes to same address. Apparently consecutive 64-bit
writes to the same address can turn into burst writes.

From:
https://github.com/parallella/oh/issues/37

Andreas:
> Remembered that we have a long forgotten mode in the epiphany chip elink
> (not impemented in the fpga elink) that creates bursts when you write
> doubles to the same address. (F**K!)
> So the writes were likely coming in as bursts.
> Looks like the mailbox works fine when you write in "int"s (I tested it on
> the board with consecutive)
> (see "mailbox_test" in elink/sw0)
