From: Philippe Mathieu-Daudé <[e-mail]>

This tests boots a Linux kernel on a Malta machine up to a
busybox shell on the serial console. Few commands are executed
before halting the machine (via reboot).

We use the Fedora 24 kernel extracted from the image at:
https://fedoraproject.org/wiki/Architectures/MIPS
and the initrd cpio image from the kerneltests project:
https://kerneltests.org/

If MIPS is a target being built, "make check-acceptance" will
automatically include this test by the use of the "arch:mips" tags.

Alternatively, this test can be run using:

  $ AVOCADO_ALLOW_UNTRUSTED_CODE=yes \
    avocado --show=console run -t arch:mips64el \
