From d2fa50e57aaf114cec20a1f2cd61f6f681672bfb Mon Sep 17 00:00:00 2001 From: Imre Kaloz Date: Thu, 5 Feb 2015 11:21:31 +0000 Subject: generic: allow ubi autoattach to run on NOR flash Some devices out there only have a NOR flash to store the rootfs on. While using UBI is arguable on this kind of flash, this is something that should be supported.
