Reworked the way RAM regions are defined. Instead of coding all the variations for each board type we now just configure RAM base and size in the usual Kconfig setup. This much simplifies the code, and makes it a lot more flexible when setting up new boards or board varients.

processor vectors at the base of RAM and then the start of the

kernel. On some platforms some RAM is reserved for boot loaders

a system with the RAM based at address 0, and leaving enough room

for the theoretical maximum number of 256 vectors.
