From 52ef6a9cb88f3202871d14e68980ad102d9dc492 Mon Sep 17 00:00:00 2001 From: Lukas Funke Date: Wed, 27 Mar 2024 13:11:52 +0100 Subject: [PATCH] spl: Introduce SoC specific init function Some architectures use spl_board_init() in their SoC specific implementation. Board developers should be able to add board specific implementation via spl_board_init(). Hence, introduce a spl_soc_init() method which is called right before spl_board_init() for SoC specific implementation.
