From 1723997610ace497252d6f9a44ec76c06951ae43 Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Thu, 19 Apr 2012 11:34:00 +0000 Subject: arm: fix bootm with device tree Commit 0a672d4 "arm: Add Prep subcommand support to bootm" re-organized do_bootm_linux() for ARM. During the re-organization, the code to pass the device tree to the kernel was removed. Add it back. This restores the ability to boot a kernel using device tree.
