f7d31df412 ehci: update the data toggle bit when reenabling an interrupt transfer. 
Previously every second transfer was dropped. We didn't notice, because
they were normally key release events, which we ignored anyway. However
the new keyboard report handler needs to see the release events.

c3bdb556d1 Move probe_usb_controller() into private functions section of usbhcd.c 
No functional change. It was just in the wrong place.

97d6c7140d Improved USB keyboard report handling. 
A USB keyboard may return key codes in any of the 6 key code array
positions (issue #48). So we have to compare the latest report to
the previous one to detect new key presses and handle rollover. As
the same change is needed for all HCI types, factor out the common
code into the base driver.

8284e98761 Don't disable bus master capability when probing USB PCI configuration. 
That can cause the SMM to freeze the system when legacy support is
enabled on some AMD XHCI controllers (issue #56).

Rework memory mapping to allow for larger program size (#54) 
* Improve abstraction in vmem.h and limit memory benchmarking to first 2GB.

The third GB may get used for remapping memory regions that are only
accessed during startup, so it's not safe to use it for the memory
speed tests.

* Fix calculation of end limit for locating memory benchmark workspace.

* Document vmem.h.

* Use window number, not current start address, to detect first window.

* Increase the program low-load range from 1MB to 4MB and make more robust.

If the BIOS has reserved some parts of low memory, there may not be
enough contiguous space left to load the program there (issue #49).
So increase the low-load range to include the first 3MB of high
memory. Also guard against the program being initially loaded
straddling the new boundary.

faab0a321d Only look for the RDSP in the appropriate EFI system table. 
We don't support mixed-mode boot, so we will never find a 32-bit EFI
system table when running from a 64-bit binary.

0939c5e127 Work around bug in SiS OHCI controllers (issue #43). 
The SiS OHCI controller ignores writes to its FmInterval and PeriodicStart
registers when in SUSPEND state, so delay initialisation of these registers
until after we start the controller running.

If the usbdebug option is present, pause at the end of the USB scan until

USB keyboards were discovered, pause for 10 seconds. Otherwise don't pause.

08bbac1065 uhci: reset the queue head after handling a keyboard interrupt. 
When an interrupt transfer completes, the UHCI loads the QELP in the
QH with the link pointer from the TD (which is a null pointer in this
case). We need to set the QELP back to point at the TD to enable the
next interrupt transfer.
