[Qemu-devel] [PULL 03/37] PPC: mpc8554ds: Tell user about exceeding RAM


From: Alexander Graf
Subject: [Qemu-devel] [PULL 03/37] PPC: mpc8554ds: Tell user about exceeding RAM limits
Date: Wed, 7 Jan 2015 16:20:14 +0100

The mpc8544ds board only supports up to 3GB of RAM due to its limited
address space.

When the user requests more, abort and tell him that he should use less.
