From 58825f74eb0156822065c449a770644a69044d88 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1/6] brcm: Fix Raspberry Pi 4B NVRAM file
NVRAM file set's boarflags3 to 0x48200100 which indicates the firmware
that an external LPO is present. But on the RPi4 no external LPO exists.
Fixes: 870b805 ("brcm: Update Raspberry Pi 3B+/4B NVRAM for downstream changes")
