Okay, I just tested icache and it appears to work okay. In blob
startup code:
mrc p15, 0, r0, c1, c0 // get current settings
orr r0, r0, #0x1000 // set icache bit
mcr p15, 0, r0, c1, c0 // turn on icache
If that is correct, then Icache isn't breaking anything. Blob and
debugging are still working okay.

I didn't realize the advantage to using zImage, other than size.
I actually thought I was making it simpler. I'll use zImage.
