Boris Shingarov ed5807381e Recognize version string "0.12" in recent OpenOCD master
Starting from 5e7612eb4, OpenOCD identifies itself as 0.12.
This causes Microwatt's flash-arty script to fail.  Because neither
the cfg nor the proxy bitstream are affected, we can keep treating
everything as indistinguishable from 0.11.  This patch simply tests
for "0.12" as an alias; it would probably be better to replace this
confusing terminology with something like "single-tap/multi-tap".

README

The Xilinx SPI flashing proxies come from here:

https://github.com/quartiq/bscan_spi_bitstreams/blob/single-tap/bscan_spi_xc7a35t.bit?raw=true
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.
