From 6eea541514461b073be89919bca2e322a2fd1bc8 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Thu, 12 Jan 2023 18:58:41 +0100 Subject: [PATCH] ARM: stm32: Pass ROM API table pointer to U-Boot proper The ROM API table pointer is no longer accessible from U-Boot, fix this by passing the ROM API pointer through. This makes it possible for U-Boot to call ROM API functions to authenticate payload like signed fitImages.
