Hi Tom,

I am trying to build the new support code of ARMv8 (using patches from David Fengua), using:

$ make vexpress_aemv8a

I will try building a DTC 1.4.0 for u-buntu by myself, but if we are saying that latest u-boot
requires DTC 1.4.0 to work well, aren't we breaking u-boot compilation on older systems like
ubuntu/fedora which have older DTC versions?
