From: Andrei Cherechesu <[email protected]> Add code for NXP S32CC platforms (S32G2, S32G3, S32R45).
S32CC platforms use the NXP LINFlexD UART driver for console by default, and rely on Dom0 having access to SCMI services for system-level resources from firmware at EL3. Platform-related quirks will be addressed in following commits.
