Nico Huber b2db28babe libpayload: Detach devices behind removed USB hubs
When a USB hub got removed, we should also remove all devices that
were attached to it.

Nico Huber ef88e102bb libpayload: More compliant error recovery in USB MSC
If an endpoint gets stalled by an MSC device, after successful
transmission of a command (CBW), we should still ask for the status
(CSW). Otherwise, the driver and the device get desynchronized on the
command tags.

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.

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

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.

delays around the disabling of control and bulk list access to
overcome some race conditions.

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 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.

Steven A. Falco 4c514aedd8 port_enable and port_reset must change atomically.
I have observed two separate EHCI host bridges that do not tolerate
using C bit-fields to directly manipulate the portsc_t register.  The
reason for this is that the EHCI spec says that port_enable must go
to 0 at the time that port_reset goes to 1.  Naturally this cannot be
done using direct bit-field manipulation.  Instead, we use a temporary
variable, change the bit-fields there, then atomically write the new
value back to the hardware.

Patrick Georgi d21f68bbd5 This patch adds USB capabilities to libpayload. It requires some
memalign implementation (eg. the one I sent yesterday).
Features:
 - UHCI controller driver
 - UHCI root hub driver
 - USB MSC (Mass Storage Class) driver
 - skeleton of a USB HID driver
   (requires better interrupt transfer handling, which is TODO)
 - skeleton of a USB hub driver
   (needs several blank spots filled in, eg. power management.
    Again: TODO)

OHCI and EHCI are not supported, though OHCI support should be rather
easy as the stack provides reasonable abstractions (or so I hope). EHCI
will probably be more complicated.

Isochronous transfers (eg. webcams, audio stuff, ...) are not supported.
They can be, but I doubt we'll have a reason for that in the boot
environment.

The MSC driver was tested against a couple of USB flash drives, and
should be reasonably tolerant by now. But I probably underestimate
the amount of bugs present in USB flash drives, so feedback is welcome.

Stefan Reinauer 56471f14db The keyboard driver mixed up the key press/release events for the
special keys.

Patrick Georgi explained:
The |0x80 codes are "break codes", that means, codes that are emitted
when the key transitions from pressed to non-pressed, so the modifier
was always in the wrong state, as soon as you pressed shift for the
first time.

Jordan Crouse e2271430c5 libpayload: Add gettimeofday() and friends
Add a gettimeofday() implementation - it works pretty well, but it
drifts a little bit so its not very suitable for keeping time.  It
works best to track changes in time over small periods of time.

Uwe Hermann fad8c2bd7c Various small consistency fixes (trivial):
- Use _FOO_H include guard format everywhere.

 - Add missing speaker.c prototypes to libpayload.h.

 - Consistently use short form u8/u16/u32 instead of uint8_t et. al.

 - kcofig: Use 'depends on' instead of 'depends', which seems deprecated.

Uwe Hermann 30d789bcbd Fix the NVRAM access functions to work correctly for the
upper 128 bytes of NVRAM (if enabled).

For most chipsets this means using I/O ports 0x72/0x73, but at least
on some VIA chipsets (I tested the VIA VT8237R on actual hardware)
these ports won't work and you have to use 0x74/0x75. Thus, make this
a Kconfig option for now.
