With these hacks, I'm able to mount flash at least read-only. On

Erase at 0x00c00000 failed immediately: -EROFS. Is the sector locked?"
Is it good news?
I see the old sharp driver has a normally-not-defined AUTOUNLOCK symbol
that would enable some code to unlock blocks before writing/erasing
(which isn't recommended since the code doesn't know the policy on
whether the block is supposed to be locked). The tree previously in use
may have had something similar setup. It seems these flashes have all
blocks locked by default at power up.
Try flash_unlock /dev/mtdX before remounting. More automatic means of
handling this are still under debate, I need to try another stab at
resolving that soon.
Looks like you're close to obsoleting the pre-CFI Sharp flash driver,
it's good news...
