xHCI driver

Hi GRUB developers,

My name is Bjørn Forsman, first time poster. I've been tasked to make
an xHCI driver for GRUB at my $dayjob. The end goal is to have smart
card (CCID) reader functionality. We already have a working CCID
driver on top of EHCI. I have no prior experience with xHCI (nor EHCI
for that matter), so this is quite the learning experience :-)

I looked in the GRUB mailing list archive and found a couple of old
threads about xHCI[1], but it looks like there has never been an
attempt at writing that driver.

Some questions:

* Is there interest in xHCI driver for GRUB? If so I can post patches
when there is something that works (more or less).

* I see the iPXE project has an xHCI driver. Any thoughts on using
that as a basis? I'm a bit unsure about the licensing, whether iPXE is
GPLv2 *only* or "at your option, any later version". I guess if it's
GPLv2+ it is compatible with GRUB's GPLv3+, or else not. Correct?

Best regards,
Bjørn Forsman

Windows - BIOS bug interaction." from late 2013 which added a quirk
for an Intel controller.
