From f795242f26887e08162b77c5ca2967f6ffcfee02 Mon Sep 17 00:00:00 2001 From: Asami Doi Date: Tue, 11 Jun 2019 16:01:31 +0900 Subject: mainboard/emulation/qemu-aarch64: Add new board for ARMv8 This CL adds a new board, QEMU/AArch64, for ARMv8. The machine supported is virt which is a QEMU 2.8 ARM virtual machine. The default CPU of qemu-system-aarch64 is Cortex-a15, so you need to specify a 64-bit cpu via a flag. To execute: $ qemu-system-aarch64 -M virt,secure=on,virtualization=on \ -cpu cortex-a53 -bios build/coreboot.rom -m 8192M -nographic Change-Id: Id7c0831b1ecf08785b4ec8139d809bad9b3e1eec Signed-off-by: Asami Doi Reviewed-on: https://review.coreboot.org/c/coreboot/+/33387 Tested-by: build bot (Jenkins) Reviewed-by: Raul Rangel Reviewed-by: Julius Werner --- src/mainboard/emulation/qemu-aarch64/mainboard.c | 23 +++++++++++++++++++++++ 1 file changed, 23 insertions(+) create mode 100644 src/mainboard/emulation/qemu-aarch64/mainboard.c (limited to 'src/mainboard/emulation/qemu-aarch64/mainboard.c') diff --git a/src/mainboard/emulation/qemu-aarch64/mainboard.c b/src/mainboard/emulation/qemu-aarch64/mainboard.c new file mode 100644 index 0000000000..573545532a --- /dev/null +++ b/src/mainboard/emulation/qemu-aarch64/mainboard.c @@ -0,0 +1,23 @@ +/* + * This file is part of the coreboot project. + * + * Copyright (C) 2019 Asami Doi + * + * SPDX-License-Identifier: GPL-2.0-or-later + */ + +#include +#include +#include +#include + +static void mainboard_enable(struct device *dev) +{ + int ram_size_mb = probe_ramsize((uintptr_t)_dram, CONFIG_DRAM_SIZE_MB); + ram_resource(dev, 0, (uintptr_t)_dram / KiB, ram_size_mb * KiB); +} + +struct chip_operations mainboard_ops = { + .name = "qemu_aarch64", + .enable_dev = mainboard_enable, +}; -- cgit v1.2.3
