Patrick Georgi 6b5bc77c9b treewide: Remove "this file is part of" lines
Stefan thinks they don't add value.

Command used:
sed -i -e '/file is part of /d' $(git grep "file is part of " |egrep ":( */\*.*\*/\$|#|;#|-- | *\* )" | cut -d: -f1 |grep -v crossgcc |grep -v gcov | grep -v /elf.h |grep -v nvramtool)

The exceptions are for:
 - crossgcc (patch file)
 - gcov (imported from gcc)
 - elf.h (imported from GNU's libc)
 - nvramtool (more complicated header)

The removed lines are:

Duncan Laurie 7724f1142e lp/drivers/usb: Add quirk for QEMU XHCI root hub
The QEMU XHCI driver does not implement the Port Change Detect bit
in the USBSTS register.  As a result no devices are attached without
looking at each port individually.

Detect this as a quirk based on the QEMU XHCI controller PCI ID,
and apply it to the root hub quirk list so it can get used by the
generic hub driver to skip this check.

With this change an attached USB mass storage device is detected and
able to boot when supplied to qemu:

  -drive if=none,id=usbmsc,format=raw,file=/tmp/disk.img
  -device qemu-xhci,id-xhci
  -device usb-storage,bus=xhci.0,drive=usbmsc

Julius Werner 6c1a669b44 libpayload: xhci: Do not memcpy registers
memcpy() is meant to be used on normal memory and often implemented with
architecture-specific optimizations to make that as performant as
possible. MMIO registers often have special access restrictions that may
be incompatible with whatever memcpy() does. For example, on arm64 it
uses the LDP (load pair) to load 16 bytes at a time, which makes 4-byte
MMIO registers unhappy.

This patch removes the caching of the XHCI capreg registers and changes
it back to a pointer. The CAP_GET() macro is still accessing a full
(non-bitfield) uint32_t at the end so this should still generate a
4-byte access (which was the goal of the original change in CB:39838).

Nico Huber e79595def5 libpayload: Use interrupt transfers for USB hubs
In interactive payloads, the USB stack's poll procedure is implicitly
called from the UI loop. Since all USB control transfers are handled
synchronously, polling hubs with these slows the UI significantly down.

So switch to interrupt transfers that are done asynchronously and only
perform control transfers when the hub reported a status change.

We use the interrupt endpoint's max packet size instead of the theo-
retical transfer length of `(bNrPorts + 1) / 8` as Linux' code mentions
hubs that return too much data.

Julius Werner 277498c283 libpayload: usbmsc: Factor out usb_msc_force_init() function
We're planning to have a use case with a custom USB device that
implements the USB mass storage protocol on its bulk endpoints, but does
not have the normal MSC class/protocol interface descriptors and does
not support class-specific control requests (Get Max LUN and Bulk-Only
Reset). We'd like to identify/enumerate the device via
usb_generic_create() in our payload but then reuse all the normal MSC
driver code. In order to make that possible, this patch factors a new
usb_msc_force_init() function out of usb_msc_init() which will
initialize an MSC device without checking its descriptors. It also adds
some "quirks" flags that allow devices registered this way to customize
behavior of the MSC stack.

Julius Werner 182fea717e libpayload: usbmsc: Skip zero-length packets at end of data
Some broken USB mass storage devices send another zero-length packet at
the end of the data part of a transfer if the amount of data was evenly
divisible by the packet size (which is pretty much always the case for
block reads). This packet will get interpreted as the CSW and screw up
the MSC state machine.

This patch works around this issue by retrying the CSW transfer when it
was received as exactly 0 bytes. This is the same mitigation the Linux
kernel uses and harmless for correctly behaving devices. Also tighten
validation of the CSW a little, making sure we verify the length before
we read any fields and checking the signature in addition to the tag.

Julius Werner 3faa2c802e libpayload: usbhid: Zero-initialize all parts of usbhid instance struct
The USBHID driver zero-initializes some but not all of the fields in its
usbhid_inst_t structure. This is a problem because under some
circumstances, some of the uninitialized fields may be read and lead to
incorrect behavior. Some (broken) USB keyboards keep sending reports
that contain all zeroes even when they have no new keys... these usually
get silently ignored, but if the usbhid_inst_t structure is in an
inconsistent state where 'previous' is zeroed out but 'lastkeypress'
is non-zero because it wasn't properly initialized, these reports will
be interpreted as keyrepeats of the bogus 'lastkeypress'. This patch
changes the code to just xzalloc() the whole structure so we won't have
to worry about initialization issues anymore.

Julius Werner 5fae829410 libpayload: usbhub: Force enumeration of all connected ports on init
We have found a non-compliant USB hub (RealTek RTS 5413) that does not
set a port's Connect Status Change bit on its USB 3.0 half if the port
had already been connected while the hub was being reset. To work around
this bug, this patch adds code to initially request the status of every
port after a hub was enumerated, clear the Connect Status Change bit if
set, and then enumerate the port iff it is currently connected,
regardless of whether the change bit was set. A similar behavior can
also be found in the Linux kernel.

Julius Werner 58caa8ba8c libpayload: Reintroduce CONFIG_LP_CHROMEOS to set suitable defaults
Chrome OS builds always have some inherent differences to "standard"
libpayload configurations: they don't want to use curses or things like
storage drivers, they always use the coreboot framebuffer and USB, etc.
This patch reintroduces CONFIG_LP_CHROMEOS as an option that only
affects Kconfig defaults. This allows Chrome OS builds to select most of
what they need in one go and reduces board-specific .config files to
only the options that are really specific to that board.

Also restricts the 8250_SERIAL_CONSOLE Kconfig to only default to yes on
x86 boards, which probably makes sense for all of libpayload (some but
far from all ARM boards use 8250-compatible UARTs, and we should
probably not default a platform option unless it's going to be correct
with very high probability).

Julius Werner 8db7e6702b libpayload: usbmsc: Add small delay during initialization to fix CZ60
We found that some SanDisk Cruizer Glide CZ60 sticks (confirmed on 16GB
and 64GB versions) have a problem responding to our first GET_MAX_LUNS
request right after they received their SET_CONFIGURATION. They will
continually return a NAK until the host gives up (which is 2
user-noticable seconds for us). Adding a small delay of about 15us seems
to be enough to fix the issue, but let's do 50 to be save.

Confirmed with both MT8173 and Intel LynxPoint XHCI controllers.

BRANCH=None
BUG=chrome-os-partner:45473
TEST=No notable delay before detecting stick on Oak and Falco.
