xilinx_bscan_spi: port to new migen and clean-up
* port to new migen * streamline package/part specification * add pullup (Series3, Series6) and pullnone (Series7) for unused pins as xilinx impact/vivado do it. * specify respective toolchains * build Series7 with vivado (broader support, faster) * point to prebuilt bitstreams at https://github.com/jordens/bscan_spi_bitstreams Change-Id: Ibfef3d78f855b754425f3e6131e2e49fa111e09a Signed-off-by: Robert Jordens <jordens@gmail.com> Reviewed-on: http://openocd.zylin.com/3173 Reviewed-by: Andreas Fritiofson <andreas.fritiofson@gmail.com> Tested-by: jenkins Reviewed-by: Robert Jördens Reviewed-by: William D.

This migen script produces proxy bitstreams to allow programming SPI flashes

Xilinx bscan cells sample TDO on falling TCK and forward it.

MISO requires sampling on rising CLK and leads to one cycle of latency.
