From a8801d8665bcc94c63a798e291a03c88f2af0215 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Mon, 27 Sep 2010 02:50:58 -0400 Subject: mtd-utils: unify flash_erase and flash_eraseall These have overlapping functionality, and while flash_eraseall supports newer 64bit ioctls, flash_erase does not. So rather than graft support onto flash_erase, merge the functionality of two into flash_erase so we only have to support one util from now on. A simple wrapper is provided to ease old flash_eraseall users into the new combined flash_erase util.
