From 2ff89d64f23e99da64995844ea42c83b0b4d58c6 Mon Sep 17 00:00:00 2001 From: Markos Chandras Date: Fri, 23 May 2014 13:31:31 +0100 Subject: [PATCH] MIPS: malta: memory.c: Initialize the 'memsize' variable If the 'memsize' environmental variable is not set by the bootloader the 'memsize' variable is not initialized, leading to potential memory problems. This patch fixes the problem by setting the initial value to '0' to force the kernel to set a good default memory size.
