From 7e5186eaae8eebc0101d539791dbff92256455ee Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Tue, 30 Oct 2007 17:18:08 +0900 Subject: [PATCH] sh: Fix up early mem cmdline parsing. memory_end was being clobbered by whatever the kernel config had specified, rather than obeying the setup option. Fix this up so that memory_end is only initialized if nothing has been set on the command line.
