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) Signed-off-by: Ola Jeppsson <ola@adapteva.com>
