One more thing: the socfpga board in Olof's boot farm fails to boot
with multi_v7_defconfig, see
http://arm-soc.lixom.net/bootlogs/arm-soc/v4.1-rc3-165-g3d58f43/socfpga-arm-multi_v7_defconfig.html

Could you have a look and see if you can reproduce that probem and send
a fix if possible? It seems to work fine with socfpga_defconfig, so maybe
it's just some Kconfig option we need to enable?
