From 896fa02c24347e6e9259812cfda187b1d6ca6199 Mon Sep 17 00:00:00 2001 From: Jiang Lu Date: Wed, 13 Nov 2013 10:38:08 +0800 Subject: [PATCH] Qemu:Arm:versatilepb: Add memory size checking The machine can not work with memory over 256M, so add a checking at startup. If the memory size exceed 256M, just stop emulation then throw out warning about memory limitation.
