From 8d6f0c787eb82ee488fddd360318cdab98159285 Mon Sep 17 00:00:00 2001 From: Wolfgang Wallner Date: Wed, 29 Oct 2025 10:22:47 +0100 Subject: [PATCH] arm: dts: brcp1: Move SPL partition to offset 0x8000 in SPI flash The ROM code of Xilinx Zynq searches the boot flash for a "BootROM header" at increments of 32k (0x8000), beginning with 0x0000 for a configuration without authentication and beginning with 0x8000 for a configuration with authentication. [1] Move the offset of the SPL partition on the brcp1 board to 0x8000 so that both cases are the same, e.g. a board that is configured without authentication can boot an SPL partition with or without authentication.
