In the case of MIPS you will have to deal with the kseg0/1 segment
size limits. From memory these are limited to 512MB. So if you have
more RAM, you would have to set up the MMU to map the excess into
useg. eCos generally doesn't use the MMU in MIPS targets, so there is
little example code, but you should be able to map everything using
one or two TLB entries.
