From: Lukas Funke Date: Wed, 27 Mar 2024 12:11:52 +0000 (+0100) Subject: spl: Introduce SoC specific init function X-Git-Url: http://git.dujemihanovic.xyz/html/static/gitweb.css?a=commitdiff_plain;h=52ef6a9cb88f3202871d14e68980ad102d9dc492;p=u-boot.git 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.
