2012-11-14libpayload: Do not call ohci_reset() from ohci_init()Nico Huber
When ohci_reset() was implemented, OHCI controllers stopped working since the stub ohci_reset() is called at the end of ohci_init(). This is fixed by removing the call. To prevent further problems the call to the xhci_reset() stub is removed, too.

2012-11-14libpayload: Document USB host controller setup functionsNico Huber
The semantics of the controller functions, start(), stop(), reset() and shutdown(), are not self-explanatory which let to some confusion. At least the reset() functions of the different host controller drivers were implemented following different interpretations. Let's make the intended behaviour of these functions clear. The stated inconsistencies will be addressed in following commits.

Some constants which were used to interpret the contents of the coreboot tables were moved to the appropriate libpayload header file. The constant which describes the maximum length of a GPIO name was renamed to have a CB_ prefix. That makes it more obvious what sort of GPIO name it describes, and reduces the change of a name collision. It also makes it more consistent with other names in that header, although some other exceptions still exist.

Those use the abbreviation le or be for little or big endian. Built for Stumpy and saw coreinfo cbfs support work which uses network byte order.

2012-06-22libpayload: Shutdown reasonably if we can't init usb msc deviceNico Huber
This lets the init of usb mass storage return if the device configuration is unusable. Also add some checks for proper shutdown so we don't free/remove an uninitialized device.

2012-06-21libpayload: Add support for interrupt transfers in OHCINico Huber
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.

This fixes some memory corruption, leaking and padding issues within the initialization of the OHCI driver.

2012-06-21libpayload: Implement correct done queue processing for OHCINico Huber
This adds correct processing of the done queue of the OHCI host controller (HC). We will always process the done queue after a control or bulk transfer. Unfortunately, it's hard to tell when the HC will write out the done queue, so we have do free the transfer descriptors later and have to allocate them one by one. 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.
