Introduce ibuf and obuf structures for helping manage memory buffers. The ibuf, an input buffer, can be read from and the obuf, an output buffer, can be written to. Helper functions are provided for serializing values in different endian formats. This library is provided to for common buffer management routines such that the same code doesn't have to re-written in different and less consistent forms.

2016-08-27cbfs: Add "struct" file type and associated helpersJulius Werner
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.

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.

2016-03-23arch/x86: introduce postcar stage/phaseAaron Durbin
Certain chipsets don't have a memory-mapped boot media so their code execution for stages prior to DRAM initialization is backed by SRAM or cache-as-ram. The postcar stage/phase handles the cache-as-ram situation where in order to tear down cache-as-ram one needs to be executing out of a backing store that isn't transient. By current definition, cache-as-ram is volatile and tearing it down leads to its contents disappearing. Therefore provide a shim layer, postcar, that's loaded into memory and executed which does 2 things: 1. Tears down cache-as-ram with a chipset helper function. 2. Loads and runs ramstage. Because those 2 things are executed out of ram there's no issue of the code's backing store while executing the code that tears down cache-as-ram. The current implementation makes no assumption regarding cacheability of the DRAM itself. If the chipset code wishes to cache DRAM for loading of the postcar stage/phase then it's also up to the chipset to handle any coherency issues pertaining to cache-as-ram destruction.

2016-02-24commonlib/lz4_wrapper: Use correct casts to ensure valid calculationsPaul Menzel
Commit 09f2921b (cbfs: Add LZ4 in-place decompression support for pre-RAM stages) breaks building cbfstool with gcc (Debian 4.9.2-10) 4.9.2 in Debian 8.3 (jessie) with a 32-bit user space. It works fine in a 64-bit user space. ``` /home/joey/src/coreboot/src/commonlib/lz4_wrapper.c:164:18: note: in expansion of macro 'MIN' size_t size = MIN((uint32_t)b.size, dst + dstn - out); ^ /home/joey/src/coreboot/src/commonlib/include/commonlib/helpers.h:29:35: error: signed and unsigned type in conditional expression [-Werror=sign-compare] #define MIN(a,b) ((a) < (b) ?

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).

2016-02-19x86: add coreboot table entry for TSC infoAaron Durbin
The 8254 (Programmable Interrupt Timer) is becoming optional on x86 platforms -- either from saving power or not including it at all. To allow a payload to still use a TSC without doing calibration provide the TSC frequency information in the coreboot tables. That data is provided by code/logic already employed by platform. If tsc_freq_mhz() returns 0 or CONFIG_TSC_CONSTANT_RATE is not selected the coreboot table record isn't created. BUG=chrome-os-partner:50214 BRANCH=glados TEST=With all subsequent patches confirmed TSC is picked up in libpayload.
