Completed moving Upstream to interrupt-based SPI.
...
Although I am not entirely convinced this is necessary, as the SPI data
stall issue only appeared with optimisation off (-O0). Perhaps re-visit
this if Upstream needs more free CPU time later...

...
with Downstream project.
Also fixed a couple of things in upstream_spi.c and

obvious...
