AFAICT, the problem is NAND being accessed simultaneously with anything else
on the eLBC (at least GPCM -- not sure about UPM). Instead of delaying the
memory-like transaction until the NAND special operation has completed, it
seems to just abort the NAND operation.
eLBC can't really tell the difference whether you've got NOR or FPGA hooked
up to a GPCM chip select, so the problem should still apply.
