XHCI (USB 3) Driver

[IanSeyler]

I've started work on a USB driver. At the moment my only interest is in getting the keyboard and mouse working. Only the XHCI controller will be targeted.

USB HID (Human Interface Devices) will be required for running BareMetal on newer hardware. Unfortunately the PS/2 port isn't found on new systems and those system aren't doing PS/2 emulation either.

Very interested in this. I'll be watching this space closely. :)

It's been just over a month since the initial announcement so I figured an update was needed.

The xHCI driver is functional with a USB keyboard.

It is working in QEMU and has also been tested on a few physical systems. There is still a lot of cleanup to be done on the code before it gets merged into master.

I've merged the code into master. There is still work to be done but it's serviceable. The multiple os_delay calls need to be removed once Interrupter 0 has proper code to deal with the events.
