From 2d896b454a0e19ec4c1ddbb0e0b65b7e54fcedf3 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Thu, 23 Feb 2017 18:04:45 +0000 Subject: [PATCH] Revert "hw/mips: MIPS Boston board support" This reverts commit d3473e147a754e999718bf6fcb015d9978c6a1ee. This commit creates a board which defaults to having 2GB of RAM. Unfortunately on 32-bit hosts we can't create boards with 2GB of RAM, and so 'make check' fails. I missed this during testing of the merge, unfortunately. Luckily the offending commit is the last one in the merge request, so we can just revert it for now.
