From 0e7db01b8ce2c2fb5596e7a9b7104e9947e5c269 Mon Sep 17 00:00:00 2001
From: Phil Elwell <phil@raspberrypi.org>

Subject: [PATCH] 2711: Add basic 64-bit support
This commit adds initial support for 64-bit 2711 builds. However,
it will only work as much as it does if the Pi4 RAM is limited to
1GB - more than that and several things break (SD card, coherent
allocations, etc.)
