[boot-wrapper PATCH 0/4] Enable new Arm architecture features

Some new Arm architecture features introduce new system registers,
access to which is guarded by SCR_EL3 bits. Since the boot-wrapper has
no interest in trapping those accesses or deny them, just unconditionally
enable them during initialisation.

Please have a look!

Cheers,
Andre
