Adds soc_term.py, a direct replacement for the soc_term tool originally
written in C [1]. This Python version is slightly simpler and does not
need to be compiled (obviously). It is therefore reasonable to have it
here in build.git for use on QEMU and QEMUv8. We can later get rid of
the soc_term project in the manifest file of those platforms.

This script is also useful with FVP, although fvp.xml does not use it;
in a custom work flow the 'xterm' command is replaced by a script which
connects the FVP telnet ports to soc_term.py via the socat command.

Buildroot, it is essential to maintain the same version of
Xen built in build system and Xen tools built in Buildroot.

DomU needs a rootfs without the Xen tools. So another target

To launch & run DomU:

make XEN_BOOT=y run

From Dom0 prompt:

> cd /mnt/host/qemu_v8/xen

I did not meet any problem running "make check" with CONFIG_JFFS2_FS=y

The image generation for the board NXP® i.MX 8MQuad Evaluation Kit (EVK)
has been refactored, so the rootfs can either be loaded from a RAMDisk
or from a partition on a media storage such as an SD card, by enabling
the compilation flag USE_PERSISTENT_ROOTFS.
In addition, the image size is now dynamically allocated, depending on
the size of the partition(s) that is/are part of the image.

The flash-image target (part of the all target) produces a out/boot.img
which can be copied to a SD card using the command:
dd if=out/boot.img of=/dev/sdX bs=1M conv=fsync

Where 'X' has to be adjusted to the device of the SD card when connected
to the host system.
