Support for configuring bootconsole and console via the ACPI tables
DBG2 (Debug Port Table 2) [1] and SPCR (Serial Port Console Redirection
Table) [2], defined by Microsoft, has been discussed on and off over the
years.

Licensing concerns have prevented this happening in the past, but as of
10 August 2015, these tables have both been released also under OWF 1.0
(http://www.openwebfoundation.org/legal/the-owf-1-0-agreements/owfa-1-0)
which is think is noncontroversially GPL-compatible?

This set is a first attempt at implementing this.

Submitting as an RFC since the SPCR handling currently depends on the
console driver being initialized after subsystem initcalls. Workaround
to enable testing surrounding infrastructure in 5/5, _really_ not
intended to be merged.
(Suggestions for acceptable ways of working around this appreciated.)

What's required for this to graduate from RFC status? Is anyone working
on it?

Thanks,

Well, we have asked Aleksey Makarov [off-list ref] to pick
this task up from Leif within Linaro.  Perhaps drop him a line and see
if the two of you can collaborate on this somehow?  I think it just needs
nudging and a bit of TLC to get it past being an RFC.
