From 72d78ec8b6898976ea46b1c0cb9780707985cd80 Mon Sep 17 00:00:00 2001
From: Phil Elwell <phil@raspberrypi.com>
Date: Thu, 19 Aug 2021 14:28:56 +0100
Subject: [PATCH] Makefiles: dt: Always set '-@' on ARCH_BCM2835
On the BCM2835 architecture, always add the '-@' option to enable the
generation of symbols, rather than relying on DTC_FLAGS being empty
or correct.
See: https://github.com/raspberrypi/linux/issues/3846
