> Will this fall over if we use printk in the bootblock on ARM without setting up the SPI controller?

Very different code now, but the current instance is using standard CBFS access in post-bootblock (and even post-verstage) code. If, at that point, SPI (or whatever bus is used for accessing CBFS) isn't set up already, something very, very weird is going on.
