From 7635a60ca848b50ff4a0ac85a667adc7151a5abf Mon Sep 17 00:00:00 2001 From: Hung-Te Lin Date: Tue, 12 Feb 2013 00:07:38 +0800 Subject: armv7: Add emulation/qemu-armv7 board. To simplify testing ARM implementation, we need a QEMU configuration for ARM. The qemu-armv7 provides serial output, CBFS simulation, and full boot path (bootblock, romstage, ramstage) to verify the boot loader functionality. To run with QEMU: export QEMU_AUDIO_DRV=none qemu-system-arm -M vexpress-a9 -m 1024M -nographic -kernel build/coreboot.rom Verified to boot until ramstage loaded successfully by QEMU v1.0.50.
