From 0e7db01b8ce2c2fb5596e7a9b7104e9947e5c269 Mon Sep 17 00:00:00 2001 From: Phil Elwell Date: Fri, 8 Mar 2019 21:12:39 +0000 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.) Signed-off-by: Phil Elwell --- arch/arm64/boot/dts/broadcom/Makefile | 1 + .../boot/dts/broadcom/bcm2711-rpi-4-b.dts | 3 + 3 files changed, 1295 insertions(+) create mode 100644 arch/arm64/boot/dts/broadcom/bcm2711-rpi-4-b.dts --- a/arch/arm64/boot/dts/broadcom/Makefile +++ b/arch/arm64/boot/dts/broadcom/Makefile @@ -3,6 +3,7 @@ dtb-$(CONFIG_ARCH_BCM2835) += bcm2837-rp bcm2837-rpi-3-b-plus.dtb dtb-$(CONFIG_ARCH_BCM2709) += bcm2710-rpi-3-b.dtb dtb-$(CONFIG_ARCH_BCM2835) += bcm2710-rpi-3-b.dtb +dtb-$(CONFIG_ARCH_BCM2835) += bcm2711-rpi-4-b.dtb dtb-$(CONFIG_ARCH_BCM2835) += bcm2710-rpi-3-b-plus.dtb dtb-$(CONFIG_ARCH_BCM2709) += bcm2710-rpi-cm3.dtb dtb-$(CONFIG_ARCH_BCM2835) += bcm2710-rpi-cm3.dtb --- /dev/null +++ b/arch/arm64/boot/dts/broadcom/bcm2711-rpi-4-b.dts @@ -0,0 +1,3 @@ +#define RPI364 + +#include "../../../../arm/boot/dts/bcm2711-rpi-4-b.dts"
