From b09e5001f3071e82ccf7ec64c9cf9a4768d660b1 Mon Sep 17 00:00:00 2001 From: Philipp Hug Date: Wed, 6 Feb 2019 06:48:51 +0100 Subject: riscv: Add initial support for 32bit boards * Adding separate targets for 32bit and 64bit qemu * Using the riscv64 toolchain for 32bit builds requires setting -m elf32lriscv * rv32/rv64 is currently configured with ARCH_RISCV_RV32/RV64 and not per stage. This should probably be changed later. TEST=Boots to "Payload not loaded." on 32bit qemu using the following commands: util/riscv/make-spike-elf.sh build/coreboot.rom build/coreboot.elf qemu-system-riscv32 -M virt -m 1024M -nographic -kernel build/coreboot.elf Change-Id: I35e59b459d1770df10b51fe9e77dcc474d7c75a0 Signed-off-by: Philipp Hug Reviewed-on: https://review.coreboot.org/c/31253 Tested-by: build bot (Jenkins) Reviewed-by: ron minnich --- src/mainboard/emulation/qemu-riscv/Kconfig | 15 +++++++++++++++ src/mainboard/emulation/qemu-riscv/Kconfig.name | 7 +++++-- 2 files changed, 20 insertions(+), 2 deletions(-) (limited to 'src/mainboard/emulation/qemu-riscv') diff --git a/src/mainboard/emulation/qemu-riscv/Kconfig b/src/mainboard/emulation/qemu-riscv/Kconfig index ecaa76468b..d15c99e966 100644 --- a/src/mainboard/emulation/qemu-riscv/Kconfig +++ b/src/mainboard/emulation/qemu-riscv/Kconfig @@ -16,6 +16,21 @@ # util/riscv/make-spike-elf.sh build/coreboot.rom build/coreboot.elf # qemu-system-riscv64 -M virt -m 1024M -nographic -kernel build/coreboot.elf + +if BOARD_EMULATION_QEMU_RISCV_RV64 + +config BOARD_EMULATION_QEMU_RISCV + def_bool y + select ARCH_RISCV_RV64 +endif + +if BOARD_EMULATION_QEMU_RISCV_RV32 + +config BOARD_EMULATION_QEMU_RISCV + def_bool y + select ARCH_RISCV_RV32 +endif + if BOARD_EMULATION_QEMU_RISCV config BOARD_SPECIFIC_OPTIONS diff --git a/src/mainboard/emulation/qemu-riscv/Kconfig.name b/src/mainboard/emulation/qemu-riscv/Kconfig.name index e9243e6837..61fd919e7c 100644 --- a/src/mainboard/emulation/qemu-riscv/Kconfig.name +++ b/src/mainboard/emulation/qemu-riscv/Kconfig.name @@ -1,2 +1,5 @@ -config BOARD_EMULATION_QEMU_RISCV - bool "QEMU riscv" +config BOARD_EMULATION_QEMU_RISCV_RV64 + bool "QEMU RISC-V rv64" + +config BOARD_EMULATION_QEMU_RISCV_RV32 + bool "QEMU RISC-V rv32" -- cgit v1.2.3
