The fw_dtb_pointer was defined in the assembly code, which makes him live in section .text_rest Put that's not necessary, we can push the variable in the .data section. This will prevent relocation errors like: board/raspberrypi/rpi/rpi.c:317:(.text.board_get_usable_ram_top+0x8): relocation truncated to fit: R_AARCH64_LDST64_ABS_LO12_NC against symbol `fw_dtb_pointer' defined in .text section in board/raspberrypi/rpi/built-in.o Signed-off-by: Matthias Brugger <mbrugger@suse.com>
