From 88d89668b9d9d4553e630c1c4ce3b0bee725e6ec Mon Sep 17 00:00:00 2001 From: Ash Charles Date: Tue, 28 Apr 2015 16:17:54 -0700 Subject: [PATCH] omap3: overo: Allow boot with kernel in UBI rootfs If regular NAND booting fails to find a valid uImage in the kernel partition in NAND, try to boot using a zImage and dtb found in a UBI volume in the rootfs partition. This is the NAND analog of mmc zImage booting for device-tree based kernels.
