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.

2013-12-21libpayload: Increase USB EHCI transfer timeoutJulius Werner
The EHCI driver defines a maximum transfer timeout of two seconds. The comments state that during tests the maximum amount of required transfer time was for the SCSI TEST_UNIT_READY command on certain devices. We have now observed a USB device (Patriot Memory 13fe:3100) that can NAK this command for slightly more than two seconds. It will also completely fail if the timeout hits, since it gets confused by the subsequent CSW retry/recovery mechanism and starts producing babble errors. This patch increases the timeout to three seconds to circumvent this problem. To test, boot a Falco from a red-black RageXT USB stick.

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.

2013-11-25libpayload: usb mass storage detect empty mediaAaron Durbin
There is currently a hard-coded 30 sec delay in the mass storage driver while waiting for each device to become ready. However, mass storage card readers that are empty return an error code on the TEST UNIT READY command. A REQUEST SENSE command then needs to be issued and interrogate the data to determine if no media is present. If no media determination is found to be true the USB device is no longer considered a candidate to be a disk. This code does lead to the fact that the media card reader needs to be populated at enumeration time. I suspect this is not an issue as it appears the storage stack in libpayload can't handle removable media coming online later. Booted recovery and dev modes. Noted that removable mass storage devices with no media were ignored without any boot delay.

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.

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.

2013-03-13libpayload: Split EHCI bulk transfers on packet boundaries over qTDsJulius Werner
EHCI controllers see transfers as a queue of transfer descriptors (qTDs), each of which can represent an aligned area of up to 20KB. Each qTD is processed separately, which means that a single USB packet cannot span multiple qTDs. While this should not be a problem according to the specification, some USB storage devices seem to get confused when a packet in the middle of a transfer is smaller than the maximum packet size (512 bytes) due to falling on a qTD boundary. This patch aligns the total transfer length per qTD to 512 bytes to avoid that problem (any excess bytes will simply roll over to the next qTD).

The linking of interrupt queues into UHCI controller's framelist (in uhci_create_intr_queue()) was incomplete. The implementation of uhci_destroy_intr_queue() was even worse, looking like it wanted to clean up more than uhci_create_intr_queue() did. This patch follows the simple approach that we used for OHCI and EHCI: Each slot in the framelist holds only one interrupt queue. Therefore, we have to look for free slots each time we want to link an interrupt queue into the framelist. In return, we have a much simpler structured framelist. With this, USB devices using interrupt transfers (e.g. keyboards) can be detached cleanly from UHCI controllers. Also, more than one of such devices can be attached without further risk.
