This chip is quite special in comparison
to the other chips. This one has two
CPUs inside of it. Currently the
linker script here and, isr vector
and such are meant mainly for the CM7,
assuming the default values of BCM7_ADD0,
using the 512K AXI SRAM.

I have yet to decide how to handle both the
CPUs at one time in this project structure.
