From 1e9e26304b77dd11b30ec983b7fa058378b29c47 Mon Sep 17 00:00:00 2001 From: Jeff Polk Date: Fri, 28 Mar 2014 17:42:43 +0800 Subject: qemu: Add addition environment space to boot loader qemu-system-mips The qemu mips malta base board boot loader uses environment strings with a max length of 256 bytes which is not long enough to accommodate a long NFS path in addition to the normal kernel boot command line arguments. The solution is to expand the environment string length to 1024 bytes.
