Subject: [PATCH] ARM: versatile: fix board support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Versatile board is used as example to run u-boot under qemu.
The patch fixes relocation for all versatile boards and adds
a versatileqemu target to be used under qemu.
Patch tested only under qemu, not on real boards.
Tested with QEMU emulator version 0.14.50.
