Existing SMC wrapper call_smc() allows only 4 parameters and
returns only one value. This is enough for existing
use in PSCI code, but TEE mediator will need a call that is
fully compatible with ARM SMCCC v1.0.
This patch adds a wrapper for both arm32 and arm64. In the ca

Some capababilities are set right during boot and will never change
afterwards. At the moment, the function cpu_have_caps will check whether
the cap is enabled from the memory.
It is possible to avoid the load from the memory by using an
ALTERNATIVE. With that the check is just reduced to 1 instru
