This MAC driver need to access System Manager's EMAC control register (secure zone) to configure the PHY interface (GMII/RGMII/RMII). This should be part of this MAC driver as well. I will add/define a high-level API in ATF to be used by this MAC driver from non-secure world (EL2). This high-level API (SMC/PSCI calls) will be properly documented in 'include/linux/intel-smc.h'
