From 4e5033b04b0faa98182ee4ba4c05b1a2de4c781b Mon Sep 17 00:00:00 2001 From: Jaehoon Chung Date: Wed, 28 Jun 2017 20:46:00 +0900 Subject: [PATCH] rpi: tizen-boot: support the booting without ramdisk image If there is not ramdisk image, target can't be booted. This modification is supported that target can be booted anyway. NOTE: Assume that ramdisk partition has "sbin". If want to mount the MMC device, you have to clear the ramdisk partition.
