Caveh Jalali 0068a9f579 add __must_check to */compiler.h
the __must_check function attribute is pretty much straight from the
linux kernel - used to encourage callers to consume function return
values.

Paul Kocialkowski d85e485c58 libpayload: video: Add support for font scaling with a factor
This introduces support for font scaling with a factor provided via
Kconfig. In practice, the font itself is not scaled at any point in
memory and only the logic to determine whether a pixel should be filled
or not is changed.

Thus, it should not significantly impact either the access time or
memory use.

Paul Kocialkowski 1c0b603673 libpayload: video: Introduce helpers for font access
This introduces helpers for accessing the included font, instead of
using hardcoded values provided by the font's header itself.

It will allow painlessly adding support for font scaling in a subsequent
change. It should not introduce any functionality change.

Nico Huber 50ab84fa37 libpayload: Clean up unaligned memset() support
Use a `for` instead of a `while` loop and use meaningful identifiers.
Also, don't use more than one variable for one and the same purpose,
don't use more (non-const) variables than necessary, don't alter more
than one variable per statement, don't compare pointers of different
types and don't do pointer arithmetic on `void *`.

This was meant as a fix up to a regression but that has already been
fixed.

Julius Werner d67c6876b5 Turn CBMEM console into a ring buffer that can persist across reboots
This patch allows the CBMEM console to persist across reboots, which
should greatly help post factum debugging of issues involving multiple
reboots. In order to prevent the console from filling up, it will
instead operate as a ring buffer that continues to evict the oldest
lines once full. (This means that if even a single boot doesn't fit into
the buffer, we will now drop the oldest lines whereas previous code
would've dropped the newest lines instead.)

The console control structure is modified in a sorta
backwards-compatible way, so that new readers can continue to work with
old console buffers and vice versa. When an old reader reads a new
buffer that has already once overflowed (i.e. is operating in true ring
buffer mode) it will print lines out of order, but it will at least
still print out the whole console content and not do any illegal memory
accesses (assuming it correctly implemented cursor overflow as it was
already possible before this patch).

Also switch set_pixel to calculate framebuffer position via
bytes_per_line instead of x_resolution. This is supposed to be the
canonical way to do that and may differ in cases where the display
controller requires a certain alignment from framebuffer lines.

Some simple implementation of the MultiBoot protocol may not pass a
memory map (MULTIBOOT_FLAGS_MMAP missing in the flags) but just the two
values for low and high memory, indicated by the MULTIBOOT_FLAGS_MEMINFO
flag.

Support those kind of boot loaders too, instead of falling back to the
hard-coded values in lib_get_sysinfo().

Tested with a multiboot enhanced version of FILO.

Simplify the code by directly using the arguments on the stack as base
pointer relative memory references, instead of loading them into

Make it more robust by preserving all callee saved registers mandated by

Don't assume anything about the register state when the called function
returns -- beside the segment registers and the stack pointer to be
still the same as before the call.

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 4fda9bd0ec libpayload: Replace majority of timer drivers with a generic one
Currently every non-x86 platform supported by libpayload needs to
provide its own timer driver. Most of the ones we have accumulated there
look almost identical: For the frequency, return a preset constant. For
the value, read a 32-bit register, possibly read another 32-bit register
and shift+OR it with the previous one, then return that.

Let's replace this with a single .c file that can easily handle all of
those cases. Menuconfig convenience can still be maintained by providing
several presets that select different defaults for the driver's
configuration options (register address(es) and frequency).

Removes an "enabled" check from Samsung MCT driver since coreboot always
unconditionally enables that timer anyway.

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

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'
file processor.

Julius Werner 1143d08f7e libpayload: head.S: Avoid clearing BSS (and heap) again
3 out of 4 architectures currently zero out the payload BSS in early
assembly code, which is pointless since the code loading the payload has
already done that (with a more efficient memset). ARM64 has never had
any code like this and can run just fine without it. This also defeats
the new optimization of moving the heap out of the BSS, since all three
implementations assume that everything between _edata and _end is BSS.
We should just take this out.

Julius Werner e25d3ff9bd libpayload: lzma: Allocate scratchpad on the heap
Allocating a 15980-byte scratchpad on the stack when your default stack
size is set to 16KB is really not a great idea. We're regularly
overflowing into the end of our heap when using LZMA in libpayload, and
just happen not to notice it because the heap rarely gets filled up all
the way. Of course, since we always *have* a heap in libpayload, the
much saner solution is to just use it directly to allocate the
scratchpad rather than accidentally grow backwards into it anyway.

The ARM64 MMU code maintains a list of used ranges, to avoid mapping the
DMA buffer over the coreboot tables and things like that. Unfortunately,
the overlap with ranges in that list is checked with

 (start1 >= start2 && start1 <= end2) || (end1 >= start2 && end1 <= end2)

region is completely contained within the first. This patch replaces

about display speed, this can become an issue if you're trying to paint

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).

When CONFIG_LP_TIMER_RDTSC is enabled honor the TSC information
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
that already exists in coreboot.

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.

Jimmy Huang c159a0ec4a arm64: mmu: Prevent CPU prefetch instructions from device memory
Set XN bit of block upper attribute to device memory in mmu. CPU may
speculatively prefetch instructions from device memory, but the IO
subsystem of some implementation may not support this operation. Set
this attribute to device memory mmu entries can prevent CPU from
prefetching device memory.

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.

If the device has already been disconnected then we shouldn't enable
host channel to start any transfer, otherwise this channel goes into
an odd state the channel is enabled but can not be disabled by set
hcchar.chdis=1. So we need check the device connect status before
enable channel.
