Joel Stanley 24a34899b4 Add files for openocd v0.11
The protocol used by the spi bridge firmware changed as of openocd
v0.11. As this is the version packaged by Debian Bullseye, add the
firmware for convince.

README

The Xilinx SPI flashing proxies come from here:

https://github.com/quartiq/bscan_spi_bitstreams/blob/single-tap/bscan_spi_xc7a100t.bit?raw=true

These are the "old" single tap versions that are supported by the openocd
release packaged in distros (0.10). If you use the wrong versions you see this:

If you find yourself with a later openocd version that contians 867bdb2e9248
("jtagspi: new protocol that includes transfer length"), such as v0.11 as
packaged by Debian Bullseye, you should use the bitstream from the master
branch:

https://github.com/quartiq/bscan_spi_bitstreams/blob/master/bscan_spi_xc7a35t.bit?raw=true
https://github.com/quartiq/bscan_spi_bitstreams/blob/master/bscan_spi_xc7a100t.bit?raw=true

These are in the microwatt repository as bscan_spi_xc7a*t_openocd_v0.11.bit.
