Subject: [PATCH 0/3] MT67XX random number generator support

These patch series introduce a generic rng driver for Trustzone
based kernel driver which would like to communicate with ATF
SIP services.

Patch #1 initials SMC fid table for Mediatek SIP interfaces and
adds HWRNG related SMC call.

Patch #2..3 adds mt67xx-rng kernel driver for Trustzone based SoCs.
For Mediatek SoCs on ARMv8 with TrustZone enabled, peripherals like
entropy sources is not accessible from normal world (linux) and
rather accessible from secure world (ATF/TEE) only. This driver aims
to provide a generic interface to ATF rng service.
