From ad83eb1ee6bb833783c4b870c86413978fb5d4ba Mon Sep 17 00:00:00 2001 From: David Milosevic Date: Thu, 16 Nov 2023 05:11:18 +0100 Subject: mainboard/emulation/qemu-sbsa: Add qemu-sbsa board Add coreboot support for qemu's sbsa-ref (Server Base System Architecture) machine (-m sbsa-ref). The qemu-sbsa coreboot port runs on EL2 and is the payload of the EL3 firmware (Arm Trusted Firmware). Note that, coreboot expects a pointer to the FDT in x0. Make sure to configure TF-A to handoff the FDT pointer. Example qemu commandline: qemu-system-aarch64 -nographic -m 2048 -M sbsa-ref \ -pflash \ -pflash The Documentation can be found here: Documentation/mainboard/emulation/qemu-sbsa.md Change-Id: Iacc9aaf065e0d153336cbef9a9b5b46a9eb24a53 Signed-off-by: David Milosevic Reviewed-on: https://review.coreboot.org/c/coreboot/+/79086 Tested-by: build bot (Jenkins) Reviewed-by: Lean Sheng Tan --- src/mainboard/emulation/qemu-sbsa/memlayout.ld | 25 +++++++++++++++++++++++++ 1 file changed, 25 insertions(+) create mode 100644 src/mainboard/emulation/qemu-sbsa/memlayout.ld (limited to 'src/mainboard/emulation/qemu-sbsa/memlayout.ld') diff --git a/src/mainboard/emulation/qemu-sbsa/memlayout.ld b/src/mainboard/emulation/qemu-sbsa/memlayout.ld new file mode 100644 index 0000000000..d178521b6e --- /dev/null +++ b/src/mainboard/emulation/qemu-sbsa/memlayout.ld @@ -0,0 +1,25 @@ +/* SPDX-License-Identifier: GPL-2.0-or-later */ + +#include +#include + +/* + * Memory map for QEMU sbsa-ref machine since + * [hw/arm/sbsa-ref.c, c6f3cbca32bde9ee94d9949aa63e8a7ef2d7bc5b] + */ +SECTIONS +{ + REGION(flash, 0x10000000, CONFIG_ROM_SIZE, 8) + + DRAM_START(0x10000000000) + BOOTBLOCK(0x10020010000, 64K) + STACK(0x10020020000, 54K) + CBFS_MCACHE(0x1002002D800, 8K) + FMAP_CACHE(0x1002002F800, 2K) + TIMESTAMP(0x10020030000, 1K) + TTB(0x10020070000, 128K) + RAMSTAGE(0x100200b0000, 16M) + REGION(fdt_pointer, 0x100210b0000, ARCH_POINTER_ALIGN_SIZE, ARCH_POINTER_ALIGN_SIZE) + + POSTRAM_CBFS_CACHE(0x10021200000, 1M) +} -- cgit v1.2.3
