[OpenWrt-Devel] [PATCH] [Resend] [kernel] mtd-partial_eraseblock_erase

[Maciej Skrzypek]

mtd: allow partial block erase
This fixes error erasing partial mtd partition which does not start on
eraseblock boundary and allows using fconfig to configure redboot on
devices such as the Gateworks Cambria.
