From mboxrd@z Thu Jan 1 00:00:00 1970 From: Marek Vasut Date: Wed, 22 Apr 2020 13:18:10 +0200 Subject: [PATCH V3 2/6] ARM: stm32: Add board_early_init_f() to SPL In-Reply-To: <20200422111814.121060-1-marex@denx.de> References: <20200422111814.121060-1-marex@denx.de> Message-ID: <20200422111814.121060-2-marex@denx.de> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de 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.
