When libpayload header files are included in the payload itself, it's possible
that the payloads config settings will conflict with the ones in libpayload.
It's also possible for the libpayload config settings to conflict with the
payloads. To avoid that, the libpayload config settings have _LP_ (for
libpayload) added to them. The symbols themselves as defined in the Config.in files
are still the same, but the prefix added to them is now CONFIG_LP_ instead of just
CONFIG_.

Well, it turned out to be more as some gaps ;)
but we finally have xHCI running. It's well tested against a QM77 Ivy
Bridge board.
We have no SuperSpeed support (yet). On Ivy Bridge, SuperSpeed is not
advertised and USB 3 devices will just work at HighSpeed.
There are still some bit fields in xhci_private.h, so this might need
little more work to run on ARM.

The current drivers for external usb hubs and root hubs all follow
the same pattern. Before adding another one with 90% of the same code,
extract the common parts and rewrite them with a simple interface.
This also adds debouncing of new attachments. Current drivers just
waited 100ms before they reset the device. However, we should check
if the device becomes disconnected and reconnected during this period.
Porting of the current hub drivers will take place in separate
commits (when I have time to test the older HCIs).

This adds a new interface for storage devices. A driver for ATA and
ATAPI drives on AHCI host controllers comes along.
The interface is very simple and was designed to match FILO's needs.
It consists of three functions:
void storage_initialize(void);
Initializes controllers. Should be called once at startup.
storage_poll_t storage_probe(size_t dev_num);
with typedef enum {
POLL_NO_DEVICE = -2,
POLL_ERROR = -1,
POLL_NO_MEDIUM = 0,
POLL_MEDIUM_PRESENT = 1,
} storage_poll_t;
Looks for a drive with number dev_num (drives are counted from
zero) and polls for a medium in the drive if appropriate.
int storage_read_blocks512(size_t dev_num,
u64 start, size_t count,
unsigned char *buf);
Reads count blocks of 512 bytes from block start of drive dev_num
into buf.

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.
