Added commment on why I'm using BSP_fatal_exit instead of bsp_fatal
and that it is required to flush the instruction cache also in
single processor configuration.

Rewrote cache manager so that it announces the operation and then
releases the lock to avoid deadlocks.

Added test program that invokes the SMP cache management functions
with ISR disabled and with the giant lock taken.
