Keith Short bf2c693f89 libpayload/usb: Increase USB request timeout to 5 s
Increase the timeout for USB requests to 5 seconds for all USB host
controllers.

Prior to this fix, the xCHI driver was detecting false timeouts during
SET ADDRESS requests when nested downstream hubs were connected to the
xHCI root hub.

BUG=b:124730179
BRANCH=sarien
TEST=Build libpayload and depthcharge on sarien/arcada.
TEST=Without change replicate USB set address timeouts in depthcharge
when dock and 4K monitor connected (which includes a total of 4 USB
hubs).  With timeout fix, depthcharge boots OS with no USB errors and
the same USB topology.  Note that this tests xHCI operation only.

Matt Delco a20e59da15 libpayload: classify all keyboards
Depthcharge uses the keyboard type to help determine whether
it can trust the keyboard for security-sensitive confirmations.
Currently it trusts anything except usb, but now there's a need
to distrust ec-based ps/2 keyboards that are associated with untrusted
ECs.  To help facilitate this, coreboot needs to report more
details about non-usb keyboards, so this change replaces the current
instances of unknown with enum values that distinguish uart and gpio
from ec-based keyboards.

BUG=b:129471321
BRANCH=None
TEST=Local compile and flash to systems with trusted and non-trusted
ECs.  Confirmed that security confirmation can't be performed via

Julius Werner 0de2fa0a62 libpayload: Deduplicate strtol and strtoull
Our strtol() and strtoull() function contain almost exactly the same
code. This is a) bad in general and b) may cause the code to get out of
sync, such as it recently happened with CB:32029.

This patch changes strtol() to be based on strtoull() so that the main
parsing code exists only once, and also adds a strtoll() to round off
the library. Also fix the bounds imposed by strtoul() to be based on the
actual length of a 'long', not hardcoded to 32-bits (which is not
equivalent on all architectures).

Our current limits.h only provides (U)INT_MAX constants. This patch adds
most others expected by POSIX. Since some of these may be different
depending on architecture (e.g. 'long' is 32-bit on x86 and 64-bit on
arm64), provide a definition that will automatically figure out the
right value for the data model the compiler is using (as long as it's
using two's complement for signed integers, which I think we can assume
these days).

Julius Werner f5b76fe9e9 libpayload: Fix CONFIG_LP_DEBUG_MALLOC for 64-bit archs
New compilers are a little more stringent about defining the same
prototype more than once, so some of our CONFIG_LP_DEBUG_MALLOC wrappers
don't quite work the way they are written anymore. Also, several of the
printf()s weren't written 64-bit safe. And let's add some
double-evaluation safety while I'm here anyway... and I have no idea why
this ever depended on CONFIG_LP_USB, that just seems like a typo.

Julius Werner d371cf3336 Make common macros double-evaluation safe
I just got hit by a double-evaluation bug again, it's time to attempt
to fix this once more. Unfortunately there are several issues that don't
make this easy:

 - bitfield variables don't support typeof()
 - local macro variables that shadow others trigger -Werror=shadow
 - sign warnings with integer literal and unsigned var in typeof-MIN()
 - ({ statement expressions }) can not be used outside functions
 - romcc doesn't support any of the fancy GCC/clang extensions

This patch tries to address all of them as far as possible with macro
magic. We don't have the technology to solve the bitfield and
non-function context issues yet (__builtin_choose_expr() still throws a
"no statement expression outside a function" error if it's only in the
branch that's not chosen, unfortunately), so we'll have to provide
alternative macros for use in those cases (and we'll avoid making
__ALIGN_MASK() double-evaluation safe for now, since it would be
annoying to do that there and having an alignment mask with side
effects seems very unlikely). romcc can continue using unsafe versions
since we're hopefully not writing a lot of new code for it. Sign
warnings can be avoided in literal/variable comparisons by always using
the type of the variable there. Shadowing is avoided by picking very
explicit local variable names and using a special __COUNTER__ solution
for MIN() and MAX() (the only ones of these you're likely to nest).

Also add DIV_ROUND_UP() to libpayload since it's a generally quite
useful thing to have.

how it works on arm32. This includes a bunch of features like actually
saving and restoring more exception state in the exception_state

useful for GDB. Since there's no instruction to directly load into or
store out of SP on arm64, we can't do quite the same thing where we use
that to read an exception_state_ptr variable right after exception entry
when no other register is available. But we can do something very
similar by (ab-)using the "high" stack pointer (SP_EL2) as a pointer to
the exception_state struct and providing a function to change it.

Julius Werner ca52a25882 libpayload: arm64: Conform to new coreboot lib_helpers.h and assume EL2
This patch adds the new, faster architectural register accessors to
libpayload that were already added to coreboot in CB:27881. It also
hardcodes the assumption that coreboot payloads run at EL2, which has
already been hardcoded in coreboot with CB:27880 (see rationale there).
This means we can drop all the read_current/write_current stuff which
added a lot of unnecessary helpers to check the current exception level.

This patch breaks payloads that used read_current/write_current
accessors, but it seems unlikely that many payloads deal with this stuff
anyway, and it should be a trivial fix (just replace them with the
respective _el2 versions).

Also add accessors for a couple of more registers that are required to
enable debug mode while I'm here.

Patrick Rudolph 7ee05eddf1 util/cbfstool: Support FIT payloads
In order to support booting a GNU/Linux payload on non x86, the FIT format
should be used, as it is the defacto standard on ARM.
Due to greater complexity of FIT it is not converted to simple ELF format.

Add support for autodecting FIT payloads and add them as new CBFS_TYPE 'fit'.
The payload is included as is, with no special header.
The code can determine the type at runtime using the CBFS_TYPE field.
Support for parsing FIT payloads in coreboot is added in a follow on
commit.
Compression of FIT payloads is not supported, as the FIT sections might be
compressed itself.

Starting at this point a CBFS payload/ can be either of type FIT or SELF.

Tested on Cavium SoC.

That doesn't give you a byte-swapped result, it gives you the same final

confused i++ and i--, so it really gives you a compiler error.)

The correct code needs to have the array index inverted relative to the
bit shift index to produce a big endian result.

Julius Werner f975e55dcd cbfs: Add "struct" file type and associated helpers
This patch adds functionality to compile a C data structure into a raw
binary file, add it to CBFS and allow coreboot to load it at runtime.
This is useful in all cases where we need to be able to have several
larger data sets available in an image, but will only require a small
subset of them at boot (a classic example would be DRAM parameters) or
only require it in certain boot modes. This allows us to load less data
from flash and increase boot speed compared to solutions that compile
all data sets into a stage.

Each structure has to be defined in a separate .c file which contains no
functions and only a single global variable. The data type must be
serialization safe (composed of only fixed-width types, paying attention
to padding). It must be added to CBFS in a Makefile with the 'struct'

Julius Werner 2296479dfd libpayload: cbfs: Add cbfs_handle API for more fine-grained accesses
The libpayload CBFS APIs are pretty old and clunky, primarily because of
the way the cbfs_media struct may or may not be passed in and may be
initialized inside the API calls in a way that cannot be passed back out
again. Due to this, the only real CBFS access function we have always
reads a whole file with all metadata, and everything else has to build
on top of that. This makes certain tasks like reading just a file
attribute very inefficient on non-memory-mapped platforms (because you
always have to map the whole file).

This patch isn't going to fix the world, but will allow a bit more
flexibility by bolting a new API on top which uses a struct cbfs_handle
to represent a found but not yet read file. A cbfs_handle contains a
copy of the cbfs_media needed to read the file, so it can be kept and
passed around to read individual parts of it after the initial lookup.
The existing (non-media) legacy API is retained for backwards
compatibility, as is cbfs_file_get_contents() (which is most likely what
more recent payloads would have used, and also a good convenience
wrapper for the most simple use case), but they are now implemented on
top of the new API.

TEST=Booted Oak, made sure that firmware screens and software sync
worked okay.

Lee Leahy f92a98c56e coreboot_tables: Extend serial port description
Extend the serial port description to include the input clock frequency
and a payload specific value.

Without the input frequency it is impossible for the payload to compute
the baud-rate divisor without making an assumption about the frequency.
This breaks down when the UART is able to support multiple input clock
frequencies.

Add the UART_PCI_ADDR Kconfig value to specify the unique PCI device
being used as the console UART.  Specify this value as zero when the
UART is not on the PCI bus.  Otherwise specify the device using bus,
device and function along with setting the valid bit.

Currently the only payload to consume these new fields is the EDK-II
CorebootPayloadPkg.

Testing on Galileo:
*  Edit the src/mainboard/intel/galileo/Makefile.inc file:
   *  Add "select ADD_FSP_PDAT_FILE"
   *  Add "select ADD_FSP_RAW_BIN"
   *  Add "select ADD_RMU_FILE"
*  Place the FSP.bin file in the location specified by CONFIG_FSP_FILE
*  Place the pdat.bin files in the location specified by
   CONFIG_FSP_PDAT_FILE
*  Place the rmu.bin file in the location specified by CONFIG_RMU_FILE
*  Build EDK2 CorebootPayloadPkg/CorebootPayloadPkgIa32.dsc to generate
   UEFIPAYLOAD.fd
*  Testing is successful when CorebootPayloadPkg is able to properly
   initialize the serial port without using built-in values.

Julius Werner 09f2921b5d cbfs: Add LZ4 in-place decompression support for pre-RAM stages
This patch ports the LZ4 decompression code that debuted in libpayload
last year to coreboot for use in CBFS stages (upgrading the base
algorithm to LZ4's dev branch to access the new in-place decompression
checks). This is especially useful for pre-RAM stages in constrained
SRAM-based systems, which previously could not be compressed due to
the size requirements of the LZMA scratchpad and bounce buffer. The
LZ4 algorithm offers a very lean decompressor function and in-place
decompression support to achieve roughly the same boot speed gains
(trading compression ratio for decompression time) with nearly no
memory overhead.

For now we only activate it for the stages that had previously not been
compressed at all on non-XIP (read: non-x86) boards. In the future we
may also consider replacing LZMA completely for certain boards, since
which algorithm wins out on boot speed depends on board-specific
parameters (architecture, processor speed, SPI transfer rate, etc.).

BRANCH=None
BUG=None
TEST=Built and booted Oak, Jerry, Nyan and Falco. Measured boot time on
Oak to be about ~20ms faster (cutting load times for affected stages
almost in half).

exported in the coreboot tables as the cpu_khz frequency. That
allows get_cpu_speed() not to be called which currently relies
on the 8254 PIT. As certain x86 platforms allow that device
to be optional or turned off for power saving reasons, allow
a path where get_cpu_speed() is no longer called. Additionally,
this approach also allows the libpayload to not duplicate logic

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.

Julius Werner bf27391da5 libpayload: Add LZ4 decompression algorithm
This patch adds support for the LZ4 decompression algorithm to
libpayload. It's what all the cool kids are using for decompression
these days and has many interesting advantages over LZMA (and everything
else I know of): blazing fast decompression (20(!) times faster than
LZMA, twice as fast as LZO on my Cortex-A72), no memory requirements on
decompression, and possibly in-place decompression support. It pays for
that with a lower compression ratio (about 50% larger compressed size
than LZMA, 10% larger than LZO for an ARM64 Linux kernel binary), but
the boot time math still works in its favor for our IO speeds.

This patch only adds the raw decompression functions for use by external
payloads, we can later try integrating them in CBFS. It copies the
decompression code itself unmodified from the upstream LZ4 library at
github.com/Cyan4973/lz4 which will hopefully make it easy to update. The
frame format parsing is reimplemented since the upstream version looks
unnecessarily complex and unreadable for our needs.
