# NOR/NAND Boot Switch - I have not read the vivi source, but from
# what I could tell from reading the registers it appears that vivi
# loads itself into DRAM and then flips NFCONT (0x4E000004) bits
-# Mode (bit 0 = 1), and REG_nCE (bit 1 = 0) which maps the NAND
-# FLASH at the bottom 64MB of memory. This essentially takes the
-# NOR Flash out of the circuit so you can't trash it.
