2017-08-10libpayload: Use a static copy of `font_glyph_filled()`Paul Menzel
libpayload needs a static copy of the out of line function `font_glyph_filled()` in every TU that needs it. So make it static inline.

2017-04-20Turn CBMEM console into a ring buffer that can persist across rebootsJulius Werner
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).

2017-02-17libpayload: x86/exec - simplify and robustify the codeMathias Krause
Simplify the code by directly using the arguments on the stack as base pointer relative memory references, instead of loading them into intermediate registers first. Make it more robust by preserving all callee saved registers mandated by the C calling convention (and only those), namely EBP, EBX, ESI and EDI. 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.

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).

2016-10-17libpayload: Replace majority of timer drivers with a generic oneJulius Werner
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.

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' file processor.

cbgfx currently makes a separate function call (recomputing some values) for every single pixel it draws. While we mostly don't care that much about display speed, this can become an issue if you're trying to paint the whole screen white on a lowly-clocked Cortex-A53. As a simple solution for these extreme cases, we can build a fast path into clear_screen() that just memset()s the whole framebuffer if the color and pixel format allow it. BUG=chrome-os-partner:54416 TEST=Screen drawing speed on Kevin visibly improves (from 2.5s to 3ms).

2016-05-17libpayload: cbfs: Add cbfs_handle API for more fine-grained accessesJulius Werner
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.

2016-05-09coreboot_tables: Extend serial port descriptionLee Leahy
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.

2016-02-22cbfs: Add LZ4 in-place decompression support for pre-RAM stagesJulius Werner
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).
