From 7b8657e2bd1ffc7a13793f18d0e069f3c9646356 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Sat, 31 Aug 2013 15:53:44 +0200 Subject: ARM: mxs: Receive r0 and r1 passed from BootROM Make sure value in register r0 and r1 is preserved and passed to the board_init_ll() and mxs_common_spl_init() where it can be processed further. The value in r0 can be configured during the BootStream generation to arbitary value, r1 contains pointer to return value from CALL'd function. This patch also clears the value in r0 before returning to BootROM to make sure the BootROM is not confused by this value. Finally, this patch cleans up some comments in the start.S file.
