From 88571c64d74163aabda3a6a9cbf1a8555536e65e Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Wed, 12 Sep 2012 19:03:12 +0000 Subject: ramips/rt305x: add initial support for Rt5350 SoC Somehow detecting the RAM size in common/setup.c doesn't work here, it always detects 64M and then crashes on devices with less RAM. Probably using MEMC_REG_SDRAM_CFG1 to know the RAM size is how it could be, for now I use the mem=32M kernel parameter to get stuff working.
