This one in particular is on the MBX860 board. It relocates the
I2C parameter ram when SCC1 is used for Ethernet.
I have since become smarter, and I am now making Linux install
it's own microcode patches. This is necessary because drivers have
to be modified to know such patches exist, as the programming
interface physically and logically changes. It is now appropriate
to reset the CPM and remove all existing configurations.

I don't remember the effect of external resets on the CPM. I am
travelling right now and don't have the book handy.
