2014-01-08libpayload: reintroduce optional PCI in XHCI driverPatrick Georgi
being a good citizen on the box, libpayload tries to return to EHCI mode on shutdown, so a non-XHCI capable USB driver after it (eg. in the OS) finds something to work with.

2013-11-25libpayload: usb mass storage card hot plugAaron Durbin
Mass storage devices such as card readers show up as as USB devices. However the media not be inserted. In those situations the previous code would just fake a disk and call usbcreate_disk. This is inappropriate because it forms a 1:1 mapping of USB device to disk leading to the inability to remove the disk and/or handle "hot plug" card insertion and removals. To alleviate this issue introduce the notion of ready to the usbmsc structure. It tracks detached, not ready, and ready states. The polling routine is then used to track not ready to ready transitions thereby creating and removing disks appropriately. This handles the case of inserting and removing a card that shows up as a new disk. Booted recovery mode. Able to observe inerstion and removal of sdcard. Also able to insert valid USB flash drive to boot as well.

2013-06-13libpayload: usb: Add interval attribute to endpointsNico Huber
Read bInterval from endpoint descriptors and store it in our endpoint_t struct. The interval is encoded dependently on the device' speed and the endpoint's type. Therefore, it will be normalized to the binary logarithm of the number of microframes, i.e. t = 125us * 2^interval The interval attribute will be used in the xHCI driver.

2013-06-13libpayload: Redirect USB slave init through controller driverPatrick Georgi
xHCI requires special treatment of set_address since it determines the device number itself (instead of the driver, as with the other controllers). The controller also wants to validate a chosen device configuration and we need to setup additional structures for the device and the endpoints. Therefore, we add three functions to the hci_t structure, namely: set_address() finish_device_config() destroy_device() Current implementation for the Set Address request moved into generic_set_address() which is set_address() for the UHCI, OCHI and EHCI drivers. The latter two are only provided as hooks for the xHCI driver. The Set Configuration request is moved after endpoint enumeration. For all other controller drivers nothing changes, as there is no other device communication between the lines where the set_configuration() call moved.

2013-03-13libpayload: Add usb_generic_(create|remove) functions for unrecognized devicesGabe Black
It might be useful to provide a USB driver in the payload itself instead of in libpayload. For example there are multiple payloads being built and linked against the same libpayload, and they might not need or even want to have the same set of drivers installed. This change adds two new functions, usb_generic_create and usb_generic_remove, which behave like the usbdisk_create and usbdisk_remove functions which are defined for USB mass storage devices. If a USB device isn't recognized and claimed by one of the built in USB class drivers (currently hub, hid, and msc) and the create function is defined, then it will be called to give the payload a chance to use the device. Once it's removed, if usb_generic_remove is defined it will be called, effectively giving the payload notice. Built and booted depthcharge on Link. Built depthcharge for Daisy. Built a netbooting payload, called usb_poll() with those functions implemented, and verified that they were called and that the devices they were told about were reasonable and the same as what was reported by lsusb in the booted system.

2012-11-14libpayload: Add init() function to hci_t and rework uhci_reset()Nico Huber
uhci_reset() differs in semantics compared to the other HCI's reset() implementations. uhci_reset() does some initialization work after a controller reset. So move the initialization part to a new function, uhci_reinit(), which get's exported through a new entry in hci_t: hci_t.init(). Warning: This breaks code that relies on the current, special, counterintuitive behaviour of uhci_reset(). If one wants a working host controller after calling hci_t.reset(), he should call hci_t.init() afterwards.

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.

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.
