[U-Boot] Using latest u-boot with HiKey board

[Peter Robinson]

Hi Peter,

Looking at u-boot on the hikey and when trying to work out what's
needed in terms of ATF and flashing of it the only information I can
find is a dead link to a readme [1] in your original post [2]. Any
chance you could add a README.hikey outlining what's required, where
it can be found, a process/offsets etc similar to README.odroid?

Peter
