From 4705b2e8047221142af2ed5e37f54ac4c7f80a7d Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Tue, 18 May 2010 14:43:15 +0000 Subject: sh: add romImage MMCIF boot for sh7724 and Ecovec V2 This patch is V2 of the MMCIF romImage boot support for sh7724 and the Ecovec board. With this patch applied and CONFIG_ROMIMAGE_MMCIF selected the romImage kernel image can be written to a MMC card and booted directly by the sh7724 cpu.
