2012-11-08Update libpayloads understanding of the coreboot tables.Gabe Black
Give it somewhere to put the new info in sysinfo, and tell it how to parse the new tables which it doesn't yet understand.

2012-11-07libpayload: Turn the "debug" #define into the usb_debug static inline function.Gabe Black
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.

2012-11-07libpayload: Take usb_poll out of usb_initialize.Gabe Black
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.

2012-11-07libpayload: Make usb_initialize more efficient and fix style problems.Gabe Black
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 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 state.
