[PATCH v4 7/9] hw/arm/raspi: Add the Raspberry Pi A+ machine |
Date: |
Sat, 24 Oct 2020 19:01:25 +0200 |
The Pi A is almost the first machine released.
It uses a BCM2835 SoC which includes a ARMv6Z core.
Example booting the machine using content from [*]
(we use the device tree from the B model):
$ qemu-system-arm -M raspi1ap -serial stdio \
-kernel raspberrypi/firmware/boot/kernel.img \
-dtb raspberrypi/firmware/boot/bcm2708-rpi-b-plus.dtb \
-append 'earlycon=pl011,0x20201000 console=ttyAMA0'
