From: Simon Glass Date: Thu, 22 Aug 2024 13:55:02 +0000 (-0600) Subject: spl: Create a function to init spl_load_info X-Git-Url: http://git.dujemihanovic.xyz/login.html?a=commitdiff_plain;h=3fd11278ff43a5039e33a8cf04dc822711ea9694;p=u-boot.git spl: Create a function to init spl_load_info Rather than having every caller set this up individually, create a common init function. This allows new fields to be added without the risk of them being left uninited.
