From 65e38e81acb0c1eb0b0478626b1985e9ae9055c6 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Wed, 22 Apr 2020 13:18:10 +0200 Subject: [PATCH] ARM: stm32: Add board_early_init_f() to SPL Add weak implementation of board_early_init_f() hook into the STM32MP1 SPL. This can be used to read out e.g. configuration straps before initializing the DRAM.
