This change modifies the code in libpayload that scans the PCI hierarchy for
USB controllers. Previously, if a devices primary function (function 0) was a
bridge, then none of the other functions, if any, would be looked at. If one
of the other functions was a bridge, that wouldn't be handled either. The new
version looks at each function that's present no matter what, and if it
discovers that it's a bridge it scans the other side.

The controller's shutdown function free()s the controller structure so
we shouldn't access it any more after calling shutdown.
As all controllers detach themself, i.e. unchain themself from usb_hcs,
just keep iterating over usb_hcs until it's NULL.

And include the new, split out version in drivers/keyboard.c and
drivers/usb/usbhid.c. Those files were including curses.h just for those
definitions, but the include path was only fixed up to to point to the
libpayload versions of those files if one of the variants of curses was
compiled in. If neither was, gcc would fall back to the system version of that
header which is wrong.

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.

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).

When checking to see if a PCI device exists at a particular bus/dev/func,
libpayload was checking the vendor and device id fields together against a 16
bit 0xffff. The two fields together are 32 bits, however, so the check was
never true, and all dev/func combinations on a particular bus would be
checked. That was slightly wasteful, but had relatively small impact.

We have to free TDs more carefully if they have been processed by the
controller yet. The current code tries to force the controller to post
them back to the done queue, but that seems wrong. We can't be sure,
when they get written back. This resulted in leaking TDs with an invalid
reference to a freed interrupt queue.
The new approach: Mark the interrupt queue to be destroyed and handle
the freeing later, when the controller posted the last TD to the done
queue.

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.

We had mixed virtual and physical pointers in struct sysinfo_t. Some
being virtual by accident which led to problems when we tried to
reinitialize lib_sysinfo after relocating FILO (to get intentionally
virtual pointers valid again). I guess this didn't cause much trouble
before, as lib_get_sysinfo() was always called with physical addresses
being equal to their virtual counterparts.
For FILO, two possibilities seem practical: Either, have all pointers in
struct sysinfo_t physical, so relocation doesn't hurt. Or, have all
pointers virtual and call lib_get_sysinfo() again after relocation.
This patch goes the latter way, changing the following pointers for
situations where virtual pointers differ from physical:
.extra_version
.build
.compile_time
.compile_by
.compile_host
.compile_domain
.compiler
.linker
.assembler
.cb_version
.vdat_addr
.tstamp_table
.cbmem_cons
.mrc_cache
We could also just correct the accidentally virtual pointers. But, IMO,
this would lower the risk of future confusion.
Note 1: Looks like .version gets never set.
Note 2: .option_table and .framebuffer were virtual pointers but treated
like physical ones. Even in FILO, this led to no problems as
they were set before relocation.

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.

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.

This adds a new interface for storage devices. A driver for ATA and

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.

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.

This introduces a dummy queue head in the interrupt frame list of the

follow pointers from this list even if the terminate bit is set.
Fortunately, they do honor the bit in queue heads and having an empty
QH in the list doesn't violate the standard.
The linux kernel has a similar workaround for AMD SB700, SB800, and
Hudson-2/3 platforms. We observed this bug with an AMD SB600.

low-speed devices on hubs in high-speed mode. This adds support for split
transactions for control and bulk transfers.

This adds proper device attachment and detachment detection and port enable-
ment to the USB hub driver. Support for split transactions is still missing,
so this works only with USB2.0 devices on hubs in USB2.0 mode and USB1.1
devices on hubs in USB1.1 mode.
