I had someone mention to me in passing that mtdinfo was failing for them
(crashing with some floating point error). I'm wondering if we've
created a divide-by-zero problem by reporting 0 erase size in /proc/mtd.
I don't have any other info and right now I don't have access to the
system I had with the mchp23lcv1024 sram.

Andrew, do you still have access to your device?
