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".

This includes the cable configuration, additions to the Python script,
and the jtagspi proxy bitstream. The single-tap version is not included
because 0.10 supported only 3-byte addresses which is unusable on the
s25fl256s anyway.

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.

By default openocd tries to "guess" the file type and interpret
it accordingly. For example it will detect an ELF file based on
the presence of an ELF header and will try to load the relevant
segments into the flash.
This may not be what we want. For example, I want to load the raw
ELF file into the flash.
Additionally the ELF parser in most distro's OpenOCD version
only supports ELF32 and will error out.
This adds a "-t" argument to flash-arty to allow us to specify the
file format. For example "-t bin" will treat the file as raw binary.
Unfortunately I had to copy and modify jtagspi.cfg from OpenOCD
to achieve this.
