Daisuke Nojiri 20b7907041 cbgfx: add get_image_dimension
get_image_dimension returns the width or height of the image projected on
canvas.

This is necessary for example when two images of different lengths have to
be placed side by side in the center of the canvas and the widths of the
images must be adjusted according to the height.

This change makes the code in graphics.c more descriptive and readable.
Especially, it makes expressions for scale calculation look what they
are meant to do. It also includes:

- Rename variables (struct fraction, dim_org, etc.) for more consistency
- Add more input validation (div-by-zero, etc.)

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.

Julius Werner e8a8a00342 libpayload: usb: dwc2: Always return 'size' transferred bytes for OUT
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 57ddd9abc7 libpayload: usb: xhci: Count new Max Scratchpad Bufs bits from XHCI 1.1
The 1.1 revision of the XHCI specification added an extra 5 bits to the
Max Scratchpad Bufs field of HCSPARAMS2 that newer controllers make use
of. Not honoring these bits means we're not allocating as many
scratchpad buffers as the controller expects, which means it will
interpret some uninitialized values from the end of the pointer array as
scratchpad buffer pointers, which obviously doesn't end well. 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.

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.

Julius Werner e44a4e8787 libpayload: usb: xhci: Prevent address reuse
We have been trying to avoid reassigning previously used USB addresses
to different devices since CL:197420, because some devices seem to take
issue with that. Unfortunately, that patch doesn't affect XHCI: those
controllers insist on chosing addresses on their own. The only way to
prevent them from reusing a previously assigned address is to not
disable that slot at all.

This patch implements address reuse avoidance on XHCI by not disabling
slots when a device is detatched (which may occur both on physical
detachment or if we simply couldn't find a driver for that device).
Instead, we just release as many resources as we can for detached
devices (by dropping all endpoint contexts) and defer the final cleanup
until the point where the controller actually runs out of resources (a
point that we probably don't often reach in most firmware scenarios).

TEST=Booted an Oak plugged into a Servo without having a driver for the

Yidi Lin d42ee150a0 libpayload: usb: Support MTK xHCI host controller
1. There is a mis-understanding to calculate the value of TD Size
   in Normal TRB. For MTK's xHCI controller it defines a number of
   packets that remain to be transferred for a TD after processing
   all Max packets in all previous TRBs, that means don't include the
   current TRB's.
2. To minimize the scheduling effort for synchronous endpoints in xHC,
   the MTK architecture defines some extra SW scheduling parameters for
   HW. According to these parameters provided by SW, the xHC can easily
   decide whether a synchronous endpoint should be scheduled in a specific
   uFrame. The extra SW scheduling parameters are put into reserved DWs
   in Slot and Endpoint Context. But in coreboot synchronous transfer can
   be ignored, so only two fields are set to a default value 1 to support
   bulk and interrupt transfers, and others are set to zero.
3. For control transfer, it is better to read back doorbell register or add
   a memory barrier after ringing the doorbell to flush posted write.
   Otherwise the first command will be aborted on MTK's xHCI controller.
4. Before send commands to a port, the Port Power in PORTSC register should

Patrick Georgi b890a1228d Remove address from GPLv2 headers
As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.

However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.

util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.

Some SOCs (like pistachio, for instance) provide an 8250 compatible
UART, which has the same register layout, but mapped to a bus of a

Instead of adding a new driver for these controllers, it is better to

Julius Werner 120aec0902 serial: Combine Tegra and Rockchip UARTs to generic 8250_mmio32
We have two drivers for a 100%-identical peripheral right now, mostly
because we couldn't come up with a good common name for it back when we
checked it in. That seems like a pretty silly reason in the long run.

Both Tegra and Rockchip SoCs contain UARTs that use the common 8250
register interface (at least for the very basic byte-per-byte transmit
and receive parts we care about), memory-mapped with a 32-bit register
stride. This patch combines them to a single 8250_mmio32 driver (which
also fixes a problem when booting Rockchip without serial enabled, since
that driver forgot to check for serial initialization when registering
its console drivers). The register accesses are done using readl/writel
(as Rockchip did before), since the registers are documented as 32-bit
length (with top 24 bits RAZ/WI), although the Tegra SoC doesn't enforce
APB accesses to have the full word length. Also fixed checkpatch stuff.

A day may come when we can also merge this driver into the (completely
different, with more complicated features and #ifdefs) 8250 driver for
x86 (which has MMIO support for 8-bit register stride only), both here
and in coreboot. But it is not this day. This day I just want to get rid
of a 99% identical file without expending too much effort.

BUG=None

Lee Leahy e32b6e7196 libpayload: PCI bus scan - Eliminate endless loop
Don't attempt to scan the PCI bus if the bridge is disabled.  When
the PCI bridge is not setup and enabled, it is possible for the
secondary bus register to contain the value zero (0).  In this case
the usb_scan_pci_bus routine gets into an infinite recursive loop
which ends only when the heap or stack is exhausted.  This patch
verifies that the PCI bridge is enabled by verifying that it is
enabled for either memory or I/O operations.  When enabled, the
secondary bus is scanned.

If a TD is comprised of one or more Normal TRBs and terminated with an

Stream state save) could occur after all the data for the TD has been
moved (e.g. after Transfer Event TRBs have been executed), but before the

Event Data TRB is necessary to complete the TD, otherwise it does not

The Evaluate Next TRB(ENT) flag provides a means of forcing the execution

Yogesh Lal 419fa61f37 libpayload: ipq808x: stale interrupt shall not be cleared unconditionally
The serial driver hangs in cases when FIFO has more than single word to be
processed. Easiest way to reproduce is to paste a string of greater than 4
characters in cli.

Clearing the RXSTALE interrupt without draining all the characters from FIFO
leads to the issue as the driver is dependent on msm_boot_uart_dm_read
function to reinitialize for next transfer.

Logically the driver is organized in such a manner that next transfer never
gets initiated till rx_data_read < total_rx_data. Clearing the RXSTALE without
consideration of total number of characters (or words) unprocessed makes the
msm_boot_uart_dm_read to return on the first if conditional. Thus the driver is
stuck forever.

A quick fix is to avoid clearing the stale interrupt. Reset is handled whenever
a new transfer is initialized in msm_boot_uart_dm_init_rx_transfer.

This adds a UART driver for the ipq8064 controller. It still does not
quite work in the receive direction - the receive FIFO returns read
data in 32 bit chunks, which means that 4 keys need to be pressed
before a character pops out of the driver (and it reports it as a
single character).

This issue is being addressed separately, the driver is being checked
in to facilitate concurrent development.

Seems that the 'if (cursor_enabled)' check in
video_console_fixup_cursor() that was removed in chromium.org 1f880bca0 really
meant to check for 'if (console)'. Looks like the whole video console
driver is built extra robust to not fail no matter how screwed up the
console is, so let's add this missing check here as well. Also fixed up
a few other missing 'if (!console)' checks while I'm at it.

However, what payloads should really be doing is check the return value
of video_(console_)init() and not call the other video functions if that
failed. This also adapts video_console_init() to correctly pass through
the return value for that purpose (something that seems to have been
overlooked in the dd9e4e58 refactoring).

Julius Werner b4fbee9a41 libpayload: video: Make cursor fixup independent of visibility
The video console runs a video_console_fixup_cursor() function after
every printed character to make sure the cursor is still in the output
window and avoid overflows. For some crazy reason, this function does
not run when cursor_enabled is false... however, that variable is only
about cursor *visibility*, and it's imperative that we still do proper
bounds checking for our output even if the cursor itself doesn't get
displayed (otherwise we can end up overwriting malloc cookies that cause
a panic on the next free() and other fun things like that).

In fact, there seems to be no reason at all to even keep track of the
cursor visibility state in the generic video console framework (the
specific backends already do it, too), so let's remove that code
entirely. Also set the default cursor visibilty in the corebootfb
backend to 0 since that's consistent with what the other backends do.

BUG=None

Julius Werner e30e4e7efa libpayload: usbmsc: Implement limited LUN support
I always thought the support for multiple logical SCSI units in the USB
mass storage class was a dead feature. Turns out that it's actually used
by SD card readers that provide multiple slots (e.g. one regular sized
and one micro-SD). Implementing perfect support for that would require a
major redesign of the whole MSC stack, since the one device -> one disk
assumption is deeply embedded in our data structures.

Instead, this patch implements a poor man's LUN support that will just
cycle through all available LUNs (in multiple calls to usb_msc_poll())
until it finds a connected device. This should be reasonable enough to
allow these card readers to be usable while only requiring superficial
changes.

Also removes the unused 'protocol' attribute of usb_msc_inst_t.

Julius Werner 7124788b33 libpayload: usbmsc: Set correct allocation length for REQUEST SENSE
So I was debugging this faulty USB SD card reader that would just fail
it's REQUEST SENSE response for some reason (sending the CSW immediately
without the data), cursing those damn device vendors for building
non-compliant crap like I always do... when I noticed that we do not
actually set the Allocation Length field in our REQUEST SENSE command
block at all! We set a length in the CBW, but the SCSI command still has
its own length field and the SCSI spec specifically says that the device
has to return the exact amount of bytes listed there (even if it's 0). I
don't know what's more suprising: that we had such a blatant bug in this
stack for so long, or that this card reader is really the first device
to actually be spec compliant in that regard.

This patch fixes the bug and changes the command block structures to be
a little easier to read (why that field was called 'lun' before is
beyond me... LUN is a transport level thing and should never appear in
the command block at all, for any command). It also fixes a memcpy() in
wrap_cbw() to avoid a read buffer overflow that might expose stack frame
data to the device.

Julius Werner 6af43804c5 libpayload: usb: Try to avoid reusing device addresses
We recently changed the USB stack to detach devices aggressively that we
don't intend to use. This alone is not really a problem, but it
exarcerbates the fact that our device detachment itself is not very
good. We destroy any local info about the device, but we don't properly
disable the offending port. The device keeps thinking that it's active,
and if we later try to reuse that device address for another device
things become confused.

The real fix would be to properly disable all ports that we don't intend
to use. Unfortunately, this isn't really possible in our current
device/hub polymorphism structure, and I don't want to hack a new
disable_port() callback into usbdev_t that really doesn't belong there.
We will only be able to fix this cleanly after we ported all root hubs
to the generic_hub interface.

Until then, an easy workaround is to just avoid reusing addresses as
long as possible. This is firmware, so the chance that we'll ever run
through 127 devices is really small in practice. Even if we ever fix the
underlying issue, it's probably a smart precaution to keep.

Julius Werner 2fe505bd9a libpayload: console: Allow output drivers to print whole strings at once
The console output driver framework in libpayload is currently built on
the putchar primitive, meaning that every driver's function gets called
one character at a time. This becomes an issue when we add drivers that
could output multiple characters at a time, but have a high constant
overhead per invocation (such as the planned GDB stub, which needs to
wrap a special frame around output strings and wait for an
acknowledgement from the server).

This patch adds a new 'write' function pointer to the
console_output_driver structure as an alternative to 'putchar'. Output
drivers need to provide at least one of the two ('write' is preferred if
available). The CBMEM console driver is ported as a proof of concept
(since it's our most performace-critical driver and should in theory
benefit the most from less function pointer invocations, although it's
probably still negligible compared to the big sprawling mess that is
printf()).

Even with this fix, the problem remains that printf() was written with
the putchar primitive in mind. Even though normal text already contains
an optimization to allow multiple characters at a time, almost all
formatting directives cause their output (including things like
padding whitespace) to be putchar()ed one character at a time.
Therefore, this patch reworks parts of the output code (especially
number printing) to all but remove that inefficiency (directives still
invoke an extra write() call, but at least not one per character). Since
I'm touching printf() core code anyway, I also tried to salvage what I
could from that weird, broken "return negative on error" code path (not
that any of our current output drivers can trigger it anyway).

A final consequence of this patch is that the responsibility to prepend
line feeds with carriage returns is moved into the output driver
implementations. Doing this only makes sense for drivers with explicit
cursor position control (i.e. serial or video), and things like the
CBMEM console that appears like a normal file to the system really have
no business containing carriage returns (we don't want people to
accidentally associate us with Windows, now, do we?).

BUG=chrome-os-partner:18390
TEST=Made sure video and CBMEM console still look good, tried printf()
with as many weird edge-case strings as I could find and compared serial

Julius Werner ab41b9daf8 libpayload: usb: Remove automatic clear_stall() calls from transfers
We've recently fixed a problem where an external hard drive would choke
due to one too many CLEAR_FEATURE(HALT) commands in the XHCI stack with
"libpayload: usb: xhci: Fix STALL endpoint handling". Clearing stall
conditions from within the transfer function is wrong in general... this
is really something that is host controller agnostic and should be left
to the higher-level driver to decide. The mass storage driver (the only
one that should really encounter stalls right now) already contains the
proper amount of clear_stall() calls... any more than that is redundant
and as we found out potentially dangerous.

This patch removes automatic clear stalls from UHCI and OHCI drivers as
well to make things consistent between host controllers.

BUG=chromium:192866
TEST=None. I could borrow the original hard drive from Shawn and compile
a Snow to only use the OHCI driver to reproduce/verify this, but alas, I
am lazy (and it's really not that important).

Julius Werner 7234d60a6e libpayload: usb: Fix up usb_shutdown() code paths
This patch combines a few minor fixes and refactoring to the various
host controller and root hub drivers to ensure they all do the right
thing on a call to usb_exit(). It puts a usb_detach_device(0) call
into detach_controller() so that the HCD doesn't need to remember to
tear down the root hub itself, and makes sure all root hubs properly
detach the subtree of devices connected to their ports first (as
generic_hub and by extension XHCI had already been doing).

It also fixes up some missing free() calls and replaces most 'ptr =
malloc(); if (!ptr) fatal()' idioms with the new x(z)alloc().

BUG=chromium:343415
TEST=Tested EHCI on Big and OHCI, EHCI, and XHCI on Snow. Could not test
UHCI (unless anyone volunteers to port coreboot to a ZGB? ;) ), but the
changes are really tame.
