Patrick Georgi a73b93157f tree: drop last paragraph of GPL copyright header
It encourages users from writing to the FSF without giving an address.
Linux also prefers to drop that and their checkpatch.pl (that we
imported) looks out for that.

This is the result of util/scripts/no-fsf-addresses.sh with no further
editing.

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.

Daisuke Nojiri a11e3ff160 cbgfx: add pivot option to draw_bitmap
This change adds 'pivot' option to draw_bitmap. It controls the point of the
image based on which the image is positioned. For example, if a pivot is set
to the center of the image horizontally and vertically, the image is
positioned using pos_rel as the center of the image.

This feature is necessary, for example, to place a text image in the center
of the screen because each image has a different width depending on the
language.

This change also makes draw_bitmap accept both horizontal and vertical size.
If either of them is zero, the other non-zero value is used to derive the
size to keep the aspect ratio.

Specifying the height is necessary to keep font sizes the same when drawing
text images of different lengths.

draw_bitmap_direct is a variant of draw_bitmap and it draws an image using
a native coordinate and the original size (as opposed to the location and
the size relative to the canvas).

CL:303074 has real use cases.

Daisuke Nojiri d66f1da846 libpayload: allow compression at file header level
Decompression is handled transparently within cbfs_get_file_content:

	const char *name = "foo.bmp";
	void *dst = cbfs_get_file_content(media, name, type, NULL);

To keep things consistent, a couple of API changes were necessary:
- cbfs_get_file_content always returns a copy of the data, even for
  uncompressed files. It's the callers responsibility to free the
  memory.
- same for cbfs_load_payload and cbfs_find_file.
- cbfs_load_optionrom doesn't take a "dest" argument anymore but always
  returns a copy of the data, for compressed and uncompressed files.
  Like with cbfs_get_file_content, the caller is responsible to free it.
  It also decompresses based on extended file attributes instead of the
  cbfs_optionrom subheader that libpayload specified but that (AFAIK)
  nobody ever used, given that there's not even tooling for that.

Seems like our transferred bytes calculation for OUT transfers that span
more than one packet had been wrong, and we just got lucky that we never
noticed it before. The HCTSIZ.xfersize register field we're reading only
counts bytes transferred by the last packet we sent.

OUT endpoints cannot have short transfers -- every transfer should
either finish all bytes we wanted to send or end in a proper error
condition. Therefore, in the absence of an error we can just conclude
that all input bytes have been transferred.

Julius Werner 6f4c7a6fde libpayload: usb: xhci: Fix list of cleared port change bits
The xhci_rh_port_status_changed() function tries to always clear all
port status bits, even though most of them don't interest us. This is
generally a smart thing to do since not clearing a status bit may cause
the controller to not generate any more Port Status Change Events.
However, the bitmask we currently use doesn't cover bit 23 (Port Config
Error Change) and instead covers bit 16 (Port Link State Write Strobe)
which is not really related to this and not a W1C bit. Probably a typo,
so let's fix that.

Julius Werner 5f9a3f7fae libpayload: xhci: Carry over fixes from Chromium tree
This patch re-adds a few fixes that originally went into the
chromeos-2013.04 tree. I kinda seem to have slipped them into the
backport of Nico's original XHCI patch (crosreview.com/168097) instead
of making a new change, which was not very clever and caused them to be
forgotten in the later upstreaming wave.

Changing internal XHCI error numbers is just a cosmetic change to make
them uniquely identifyable in debug output. Bumping the timeout to 3
seconds is an actually important fix since we have seen mass storage
devices needing that much in the past.

BRANCH=None
BUG=None
TEST=Diffed payloads/libpayload/drivers/usb between chromeos-2013.04 and
chromeos-2015.07, confirmed that no serious differences remain.

Aaron Durbin e3260ec29a libpayload: usb: don't prematurely free the usb device
Before the controller's destroy_device() could interrogate
the usbdev_t object usb_detach_device() was freeing and
NULLing out the pointer. That results in all callers who
needed that object to start accessing random bits of memory.

This eventually led into free()ing memory it shouldn't which
corrupted the allocator's state. Eventually, all forward
progress was lost by way of a single ended linked list
turning into a circular list.

The culprit seems to be a bad merge in commit e00ba21.
