Nico Huber e8a71d34cd libpayload: Fix random warnings
dump_td() is orphaned but looks useful => commented out.

The delay identifier shadowed the global one => renamed to total_delay.

Nico Huber ba22e4c3fd libpayload: Fix some missing-prototype warnings
usb_controller_initialize() is not declared in any header file nor
called from outside of usbinit.c, so make it static.

set_configuration() looks like beeing non-static on purpose (like the
other helpers around it in usb.c), so put a prototype into usb.h.

Nico Huber 425973cf42 libpayload: Always use virtual pointers in struct sysinfo_t
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.

Nico Huber 6e711c6a97 libpayload: Add init() function to hci_t and rework uhci_reset()
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.

This is fixed by removing the call. To prevent further problems the call

Built for Stumpy and saw coreinfo cbfs support work which uses network
byte order. Used the functions which convert to little endian to implement an
AHCI driver. The source arch is also little endian, so they were effectively
(and successfully) inert.

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.

Nico Huber 1f6bd94fa8 libpayload: New AHCI, ATA and ATAPI drivers
This adds a new interface for storage devices. A driver for ATA and
ATAPI drives on AHCI host controllers comes along.

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.

Nico Huber 274c63e367 libpayload: Add support for interrupt transfers in OHCI
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.

Nico Huber 9951adeffd libpayload: Implement correct done queue processing for OHCI
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 enables logical detachment of unresponsive usb devices (i.e.
devices not responding to control transfers) in the usb mass storage

Nico Huber 3ca35cae35 libpayload: Add dummy queue heads to EHCI interrupt frame list
This introduces a dummy queue head in the interrupt frame list of the
EHCI host controller. It's a workaround for broken controllers which
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.

Nico Huber 0d120f8ee2 libpayload: Add interrupt-queue underrun recovery to EHCI
If the queue of an interrupt transfer runs out, we have to reset
the queue head. This also introduces the use of a spare transfer
descriptor (TD) in interrupt queues, which assures, that a processed
TD  won't be reused until the host controller has written it back
from his overlay.
