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=3Dpl011,0x20201000 console=3DttyAMA0'
