Yes we need to make the determination of how to use HalCoGen. I'm not
sure if I prefer to include HalCoGen generated code in the git
repository, or just to document how an end user should add the
HalCoGen files themselves. I think I prefer to include the generated
files, since it is then easier to quality control.

Does this mean the driver framework we have in cpukit/dev/spi cannot
be used? In this case the SPI driver will have to be developed from
scratch as part of the BSP.

First get the console to work. Console + one context switch = hello
world. So the first step is to get hello world to work properly.
