Does anyone have any experience with changing the bootmap bit in
SYS_CNTRL on the fly? I am trying to change it to 1 to access an
external peripheral in program space, but the processor appears to
reset/crash when I do this. I'd like to be able to change it to 1,
read the peripheral and then change it back to zero so I can still
access the bootflash.

This is basically what I was trying, except that I was using a bit set/bit
clear. I tried it your way and still have the same problem... the processor
resets/crashes.
Also, I noticed you showed SYS_BASE defined as 0x0, I believe it should be
0xc00 or am I missing something?
