The "debug" macro used internally in the libpayload USB subsystem was very
generically named and would leak into consumers of the library that included
usb.h directly or indirectly. This change turns that #define from a macro into
a static inline function to move away from the preprocessor, and also renames
it to usb_debug so it's less likely to collide with something unrelated.

While it might be slightly more convenient to not have to call usb_poll
manually after calling usb_initialize, you'll still likely want to call it
before trying to use a USB device since one have have been hotplugged since
you last looked. By not calling usb_poll, usb_initialize completes quickly and
can be called unconditionally without a long delay. The delay can be put off
until later when we're sure it's necessary.

The usb_initialize function would scan for USB host controllers by brute force
iterating over all possible busses, devices, and functions. This change makes
it recursively scan busses only if it finds them on the other side of a bridge,
and only scan for functions beyond function 0 if the device claims to be
multifunction.
This change also takes the opportunity to clean up some style problems
throughout the file.

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.

This adds support for usb interrupt transfers to the OHCI driver.
Basically this enables support for HID keyboard devices.
For each interrupt transfer endpoint, two queues of transfer
descriptors (TDs) are maintained: the first with initialized TDs
is linked to the periodic schedule of the host controller (HC), the
second holds processed TDs which will be polled by the usb class
driver. The HC moves processed TDs from its schedule to a done queue.
We periodically fetch all TDs from the done queue, to put them on the
queue associated with the endpoint, where they can be polled from.
Fully processed TDs (i.e. which have gone throuch all of this) will be
reinitialized and put on the first queue again.

To distinguish different types of TDs (e.g. async vs. interrupt
transfers) on the done queue, they are flagged in the lsb of there
.config field. We can utilize this bit for our own purpose, as it's
reserved and the host controller won't interpret it and preserves its

Fortunately, they do honor the bit in queue heads and having an empty

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.
