[PATCH 17/20] arm: SC584-EZKIT initial support

Oliver Gaskell via B4 Relay devnull+Oliver.Gaskell.analog.com at kernel.org
Wed Aug 28 12:02:25 CEST 2024 

From: Oliver Gaskell <Oliver.Gaskell at analog.com>

Adds support for Analog Devices' SC584-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
