[PATCH] mtd: add OTP (one-time-programmable) erase ioctl

[Tudor.Ambarus at microchip.com]

Michael,

Would you please resend this patch, together with the mtd-utils
and the SPI NOR patch in a single patch set? You'll help us all
having all in a single place.

For the new ioctl we'll need acks from all the mtd maintainers
and at least a tested-by tag.

Cheers,
ta
