-Subject: [PATCH 3/7] arm: mach-bcm283x: Define configs for RaspberryPi 4
-
-Define two target configs for Raspberry Pi 4 (32 and 64bit) and the
-corresponding BCM2838* configs.
-
-Be aware of the current limitation in firmware which requires an
-explicit configuration to force the arm in 64bit mode when the
-respective target is used.
