This allows us to use the same DRAM init function on all archs. Add a dummy function for arc, which does not use DRAM init here. Signed-off-by: Simon Glass <sjg@chromium.org> [trini: Dummy function on nios2] Signed-off-by: Tom Rini <trini@konsulko.com> |

Freescale Amadeus Plus M5253EVBE board ====================================== Hayden Fraser(Hayden.Fraser@freescale.com) Created 06/05/2007 =========================================== 1. SWITCH SETTINGS ================== 1.1 N/A 2. MEMORY MAP UNDER U-BOOT AND LINUX KERNEL =========================================== 2.1. For the initial bringup, we adopted a consistent memory scheme between U-Boot and linux kernel, you can customize it based on your system requirements: SDR: 0x00000000-0x00ffffff SRAM0: 0x20010000-0x20017fff SRAM1: 0x20000000-0x2000ffff MBAR1: 0x10000000-0x4fffffff MBAR2: 0x80000000-0xCfffffff Flash: 0xffe00000-0xffffffff 3.

COMPILER ----------- To create U-Boot the CodeSourcery's version of the GNU Toolchain for the ColdFire architecture compiler set (freescale-coldfire-4.1-elf) from www.codesourcery.com was used. You can download it from:http://www.codesourcery.com/gnu_toolchains/coldfire/download.html compiler that you used - for example, codesourcery_elf requires -MQ in rules.mk, old M68K 2.95.3 just -M codesourcery_elf requires -MQ in rules.mk, old M68K 2.95.3 just -M
