 Renesas RZ/G
 ============

 The "RZ/G" Family of high-end 64-bit Arm®-based microprocessors (MPUs)
 enables the solutions required for the smart society of the future.
 Through a variety of Arm Cortex®-A53 and A57-based devices, engineers can
 easily implement high-resolution human machine interfaces (HMI), embedded
 vision, embedded artificial intelligence (e-AI) and real-time control and
 industrial ethernet connectivity.

 The scalable RZ/G hardware platform and flexible software platform
 cover the full product range, from the premium class to the entry
 level. Plug-ins are available for multiple open-source software tools.

 Overview
 --------
 On RZ/G2 SoCs the BOOTROM starts the cpu at EL3; for this port BL2
 will therefore be entered at this exception level (the Renesas' ATF
 reference tree [1] resets into EL1 before entering BL2 - see its
 bl2.ld.S)

 BL2 initializes DDR before determining the boot reason (cold or warm).

 Once BL2 boots, it determines the boot reason, writes it to shared
 memory (BOOT_KIND_BASE) together with the BL31 parameters
 (PARAMS_BASE) and jumps to BL31.

 To all effects, BL31 is as if it is being entered in reset mode since
 it still needs to initialize the rest of the cores; this is the reason
 behind using direct shared memory access to  BOOT_KIND_BASE _and_
 PARAMS_BASE instead of using registers to get to those locations (see
 el3_common_macros.S and bl31_entrypoint.S for the RESET_TO_BL31 use
 case).

 How to build
 ------------

 The TF-A build options depend on the target board so you will have to
 refer to those specific instructions. What follows is customized to
 the HiHope RZ/G2M development kit used in this port.
