From ecd6fd02e1225e6e0d44005f4f25747d29794ddf Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Mon, 12 May 2025 18:45:14 +0200 Subject: [PATCH] ARM: stm32: Auto-detect ROM API table on STM32MP15xx The ROM API table location is passed to the SPL by BootROM in register r0, make use of this, store the content of r0 and later use it to access the ROM API table to determine current boot device.
