[U-Boot] [PATCH] Move Cache-As-RAM memory from area mapped to ROM in QEMU

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

Bin, are you happy with this? Do you want this in before release? Thanks!

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)

Thank you Heinrich, I can confirm that current u-boot master works without reverting aaaa55751ab1. I had problems with u-boot v2017.11-rc2 apparently.
Best regards, Anton Gerasimov

Could you, please, resubmit the patch with an updated commit message.
