25f814a3 update ppsi to fix 1-pps generation in Master mode

PPS csync is asserted one 125MHz ref clock cycle before the actual PPS. It can be used for aligning another signal to the PPS.

platform/xilinx: add generics to Xilinx platform to select which GTP channel to use (defaults to ch1)

a2dd8bb9: spec_defconfig: remove spaces from built-in init script

txts -> dio_p/n_o[2] (= Lemo 3)
rxts -> dio_p/n_o[1] (= Lemo 2; formerly used for 62.5 MHz RefClk)

Since generic fifo has been fixed in general cores, the threshold values have been corrected accordingle and the threshold for transmission needn't have an offset to work

wrpc-sw:
24ebdb55: print also built-in init script with _init show_ cmd

Final version of the testbench.Fully working with 6 different tests: flush, timeout, tx_thr, tx_max words, fxd latency, drop frames.
