ROM has been made read-only in qemu recently (namely commit 208fa0e43645edd0b0d8f838857dfc79daff40a8), so this patch restores compatibility between u-boot and qemu. It is still broken for me unless I set CONFIG_SMP=n and disable lapic (i.e. revert patch aaaa55751ab1e5a5cfa0962d604593a7e6f33ff6 in u-boot), but these are separate issues
I could not reproduce that reverting aaaa55751ab1 is necessary. Your patch and CONFIG_SMP=n was suffcient to start U-Boot with qemu-system-x86_64 version 2.10.1(Debian 1:2.10.0+dfsg-2)
