I have observed two separate EHCI host bridges that do not tolerate
using C bit-fields to directly manipulate the portsc_t register. The
reason for this is that the EHCI spec says that port_enable must go
to 0 at the time that port_reset goes to 1. Naturally this cannot be
done using direct bit-field manipulation. Instead, we use a temporary
variable, change the bit-fields there, then atomically write the new
value back to the hardware.

memalign implementation (eg. the one I sent yesterday).
Features:
- UHCI controller driver
- UHCI root hub driver
- USB MSC (Mass Storage Class) driver
- skeleton of a USB HID driver
(requires better interrupt transfer handling, which is TODO)
- skeleton of a USB hub driver
(needs several blank spots filled in, eg. power management.
Again: TODO)
OHCI and EHCI are not supported, though OHCI support should be rather
easy as the stack provides reasonable abstractions (or so I hope). EHCI
will probably be more complicated.
Isochronous transfers (eg. webcams, audio stuff, ...) are not supported.
They can be, but I doubt we'll have a reason for that in the boot
environment.
The MSC driver was tested against a couple of USB flash drives, and
should be reasonably tolerant by now. But I probably underestimate
the amount of bugs present in USB flash drives, so feedback is welcome.

The |0x80 codes are "break codes", that means, codes that are emitted

This enables using the ACS_ curses macros with libpayload.
The translation from ACS_ macros (or characters with attribute A_ALTCHARSET)
is done using one acs map for the video console, one for serial console
(xterm/vt100/vt220), and one fallback, from which an ASCII substitute is
taken if the device specific map doesn't contain an entry (ie NUL).
