The Renesas RZ/G2L SMARC Evaluation Board Kit consists of the RZ/G2L System-on-Module (SOM) based on the R9A07G044L2 SoC, and a common SMARC carrier board.
The ARM TrustedFirmware code for the Renesas RZ/G2L SoC family passes a devicetree blob to the bootloader as an argument in the same was previous R-Car gen3/gen4 SoCs. This blob contains a compatible string which can be used to identify the particular SoC we are running on and this is used to select the appropriate device tree to load.
The configuration renesas_rzg2l_smarc_defconfig is added to support building for this target. In the future this defconfig will be extended to support other SoCs and evaluation boards from the RZ/G2L family.

- Move dram_init() & dram_init_banksize() to memmap-rzg2l.c
- Add a TODO note for reset support.

You could add this piece ^ in patch 17/19 already.
