From 44174343688dba32571a34550dba08971c65fef1 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Tue, 18 Nov 2008 16:36:22 +0100 Subject: [PATCH] MIPS: Add CONFIG_SKIP_LOWLEVEL_INIT This patch adds the CONFIG_SKIP_LOWLEVEL_INIT option to start.S. This enables support for boards where the lowlevel initialization is already done when U-Boot runs (e.g. via OnChip ROM). This will be used in the upcoming VCTH board support.
