From ecdfd69a4be55363589e8185ff151b02e6c36cfa Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sat, 24 Sep 2016 18:19:57 -0600 Subject: spl: Convert boot_device into a struct At present some spl_xxx_load_image() functions take a parameter and some don't. Of those that do, most take an integer but one takes a string. Convert this parameter into a struct so that we can pass all functions the same thing. This will allow us to use a common function signature.
