[PATCH 13/20] arm: SC598-SOM-EZKIT initial support
Oliver Gaskell via B4 Relay
devnull+Oliver.Gaskell.analog.com at kernel.org
Wed Aug 28 12:02:21 CEST 2024
From: Oliver Gaskell <Oliver.Gaskell at analog.com>
Adds support for Analog Devices' SC598-SOM-EZKIT board. Includes:
- CONFIG options common to all SC5xx SoCs
- 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
