From a23e277c4a3a2bbc42d237aae29da3a8971e757f Mon Sep 17 00:00:00 2001 From: Haavard Skinnemoen Date: Mon, 19 May 2008 11:36:28 +0200 Subject: avr32: Rework SDRAM initialization code This cleans up the SDRAM initialization and related code a bit, and allows faster booting. * Add definitions for EBI and internal SRAM to asm/arch/memory-map.h * Remove memory test from sdram_init() and make caller responsible for verifying the SDRAM and determining its size. * Remove base_address member from struct sdram_config (was sdram_info) * Add data_bits member to struct sdram_config and kill CFG_SDRAM_16BIT * Add support for a common STK1000 hack: 16MB SDRAM instead of 8.
