[Xen-devel] [PATCH RFC OSSTEST 06/19] ts-host-install: Refactor code to construct a Linux console= for a host

[Ian Campbell <ian.campbell@xxxxxxxxxx>]

And reuse it in when writing the u-boot script for initial boot. This was
previously hardcoded to ttyAMA which matches the production host DB for the
current set of hosts which use this script.
