[SeaBIOS] [PATCH 0/5] Add USB EHCI controller support.

[Kevin O'Connor]

This patch set adds support for high-speed USB (EHCI) controllers.
I've tested this on my epia-cn machine.  The EHCI support noticeably
decreases the time required to boot from a USB drive.

This support includes the code necessary to hand off full/low speed
devices to "companion controllers" (both uhci and ohci).  It also
supports full/low speed devices attached to high-speed hubs.

This is an initial implementation, but I think it's ready for more
wide spread testing.  Feedback is welcome.

Kevin O'Connor (5):
  Dynamically allocate USB controller structures.
  Reduce size of USB 'struct uhci_td'.
  Minor - USB OHCI interrupt queue should be one larger.
  Some USB UHCI and OHCI fixes and cleanups.
  Add USB EHCI controller support.
