The SCP firmware is a critical piece for the Juno, but the problem is that it
can't be built from any repository I think.
@Liviu: Could you please confirm this info?

If the SCP firmware exists as a binary only, then we have to include it in
/board/arm/juno folder for building the ATF out-of-the-box.

Opinions?
