From 46e0ac55e56638d2543fc5a4c1ed28470095233e Mon Sep 17 00:00:00 2001 From: Ilias Apalodimas Date: Sat, 15 Nov 2025 09:33:29 +0200 Subject: [PATCH] rpi: Fix compilation with larger configs Tom reports that adding more Kconfig options fails with board/raspberrypi/rpi/lowlevel_init.o: in function `save_boot_params': board/raspberrypi/rpi/lowlevel_init.S:20:(.text+0x0): relocation truncated to fit: R_AARCH64_ADR_PREL_LO21 against symbol `fw_dtb_pointer' defined in .data section in board/raspberrypi/rpi/rpi.o make: *** [Makefile:2029: u-boot] Error 1 Since fw_dtb_pointer lives in .data it might end up above the +-1MB that adr can reach. So switch over to adrp+add which has a +-4gb reach.
