* drivers/mtd/flash_eraseall.c: Removed. This is no longer used

in the OS and is simply a wrapper around the MDIOC_BULKERASE

IOCTL command. It used to be called (only) from
|
||||
apps/system/flash_eraseall, but that has been removed because it
|
||||
violated the OS/applicatin interface -- by calling flash_eraseall().
|
||||
The old code can be found in the Obsoleted' repository (2016-06-03).
