[PATCH v2 17/20] arm: SC584-EZKIT initial support
Oliver Gaskell via B4 Relay
devnull+Oliver.Gaskell.analog.com at kernel.org
Thu Sep 12 17:50:58 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
- SPL config options in common/spl/Kconfig
- Necessary board-specific init functions
- Board-specific Kconfig and environment in board/adi/
- Memory configuration
