From: Oliver Gaskell <oliver.gask...@analog.com>
Adds support for Analog Devices' SC594-SOM-EZKIT board. Includes:
- SoC specific configs in mach-sc5xx/Kconfig
- Memory Map for SPL
- Necessary board-specific init functions
- Board-specific Kconfig and environment in board/adi/
- Memory configuration
