From 196c74311f394c6eb08bd9ab07a35671299b9851 Mon Sep 17 00:00:00 2001 From: Kyungmin Park Date: Tue, 3 Mar 2009 09:05:53 +0900 Subject: Reduce OneNAND IPL common code OneNAND IPL has common codes for RAM init, load data, and jump to 2nd bootloader, but it's common code used about 300~400 bytes. So board specific codes, such as lowlevel_init, can't has enough code. It make a difficult to implement OneNAND IPL. his patch make this common code as small as possible. and give lowlevel_init can have more codes.
