This means that the secondary cores will miss out on any setup which the
bootloader might have done for the primary CPU, e.g. switching to NS HYP
mode, setting the CNTFRQ etc.
Wouldn't it be better to do all this stuff in the bootloader and either
implement PSCI or have the bootloader do the traditional holding pen and
mbox address thing?
