c79f831b63 rtl: version: always include git revision 
Even when building a tagged release, include the git revision.  This
prevents the git revision from being reported as `00000000`.

8802d488c5 hw: foboot-bitstream: fix no-cpu build 
When building without a CPU, the `self.cpu` property is not None, but
rather CPUNone.  This change was made upstream and broke no-cpu builds.

Fix these builds by checking for an instance of CPUNone.

405918134e foboot-bitstream: encode spi flash information into platform 
Different platforms have different spi flash sizes and different numbers
of dummy bits to send.  Encode this information in the platform to
simplify spi flash addition.

Reordering the file seems to improve timing by quite a lot, even after
adjusting the pnr seed.  With this reordering we now meet timing.

ce777d5057 bitstream: touch: remove "field" support to fix inputs 
The "touch" block doesn't need field support, since it's just one field.
Remove support, which simplifies the layout and unbreaks "input"
support.
