Multiprocessing bootup sequence for BSP

I'm trying to put together a BSP for a cpu which has many MIPS cores
connected via a fully coherent memory system, and I guess I'm fishing for
ideas about how to structure my memory map and bootup sequence. The problem
is that, with one RTEMS memory image, the processors executing the code will
overwrite each other's bss sections, etc. However, having a single RTEMS
image for each processor seems wasteful, as the cpus could and should share
one text section. Also, at bootup I'd certainly like to have only one copy
of the RTEMS image in ROM, from which I'd like to derive all of the images
which all of the cpus use. Any suggestions?
John
