From: Philippe Mathieu-Daudé <f4bug@amsat.org>

Add a test which boots Linux and run basic commands using the serial
port console.

The kernel image is built by the Debian project:
https://wiki.debian.org/RaspberryPi

The DeviceTree blob comes from the official Raspberry Pi project:
https://www.raspberrypi.org/

The cpio image used comes from the linux-build-test project:
https://github.com/groeck/linux-build-test

This test can be run using:

v2: Use archive.gzip_uncompress (Cleber)

some chars are scrambled on the console?
Cleber ran this 100 times and doesn't have issue.

Now, I'm not getting good vibes from this test.  It spawns QEMU and
then gets stuck on every single execution.

VM launch command: 'aarch64-softmmu/qemu-system-aarch64 -chardev socket,id=mon,path=/var/tmp/tmpgpee0g1h/qemu-23397-monitor.sock -mon chardev=mon,mode=control -display none -vga none -machine raspi3 -chardev socket,id=console,path=/var/tmp/tmpgpee0g1h/qemu-23397-console.sock,server,nowait -serial chardev:console -kernel /var/tmp/avocado_7ks9sppd/avocado_job_wsp2727i/1-tests_acceptance_boot_linux_console.py_BootLinuxConsole.test_arm_raspi3_initrd_uart0/boot/vmlinuz-4.14.0-3-arm64 -dtb /home/cleber/avocado/data/cache/by_location/cd5c65e442f2375a87c174b91963be739bcdae77/bcm2710-rpi-3-b.dtb -initrd /var/tmp/avocado_7ks9sppd/avocado_job_wsp2727i/1-tests_acceptance_boot_linux_console.py_BootLinuxConsole.test_arm_raspi3_initrd_uart0rootfs.cpio -append printk.time=0 earlycon=pl011,0x3f201000 console=ttyAMA0 panic=-1 noreboot -no-reboot'
>>> {'execute': 'qmp_capabilities'}
<<< {'return': {}}

Given that I've tested this before, and I see some changes to raspi3
since then, I'll try to bisect the possible culprit.  If you have any
clues, they would be much appreciated.

- Cleber.

With the previous refactors to wait_for_console_pattern(), this should become:

        wait_for_console_pattern(self,
                                 'Boot successful.',
                                 failure_message='-----[ cut here ]-----')
