It does the magic to boot the host

Relying on the command-status is dicey, the GPIO arbitration
code needs a more reliable way to know we are actually running

We now use a portion of the ucode itself for version information
and to configure the base of SRAM, this will allow the driver
to use a pool allocator with less constraints.
We put the status register as part of the command register, this
speeds things up a bit and remove the need to clear it from
the host.
We also turn some SRAM stores from byte to long stores, they seem
to be faster (still room for improvement)

This will be used by the kernel GPIO driver to synchronize
with the CF when accessing GPIO shared with FSI.

seems to be the best value for performance
