2016-05-11cbfstool/fsp: Rename fsp1_1_relocateFurquan Shaikh
FSP 2.0 uses the same relocate logic as FSP 1.1. Thus, rename fsp1_1_relocate to more generic fsp_component_relocate that can be used by cbfstool to relocate either FSP 1.1 or FSP 2.0 components. Allow FSP1.1 driver to still call fsp1_1_relocate which acts as a wrapper for fsp_component_relocate.

2016-05-11util/cbfstool: Allow xip/non-xip relocation for FSP componentFurquan Shaikh
Currently, convert_fsp assumes that the component is always XIP. This is no longer true with FSP 2.0 and Apollolake platform. Thus, add the option -y|--xip for FSP which will allow the caller to mention whether the FSP component being added is XIP or not. Add this option to Makefiles of current FSP drivers (fsp1_0 and fsp1_1).

2016-05-09drivers/uart: Use uart_platform_refclk for all UART modelsLee Leahy
Allow the platform to override the input clock for the UART by implementing the routine uart_platform_refclk and setting the Kconfig value UART_OVERRIDE_REFCLK. Provide a default uart_platform_refclk routine which is disabled when UART_OVERRIDE_REFCLK is selected. This works around ROMCC not supporting weak routines. 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.

2016-05-09drivers/uart: Enable override for input clock dividerLee Leahy
Allow the platform to override the input clock divider by adding the uart_input_clock_divider routine. This routine combines the baud-rate oversample divider with any other input clock divider. The default routine returns 16 which is the standard baud-rate oversampling value. A platform may override this default "weak" routine by providing a new routine and selecting UART_OVERRIDE_INPUT_CLOCK_DIVIDER. This works around ROMCC not supporting weak routines.

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.

Our EDID code had always been aligning the framebuffer's bytes_per_line (and x_resolution dependent on that) to 64. It turns out that this is a controller-dependent parameter that seems to only really be necessary for Intel chipsets, and commit 6911219cc (edid: Add helper function to calculate bits-per-pixel dependent values) probably actually broke this for some other controllers by applying the alignment too widely. This patch makes it explicitly configurable and depends the default on ARCH_X86 (which seems to be the simplest and least intrusive way to make it fit most cases for now... boards where this doesn't apply can still override it manually by calling edid_set_framebuffer_bits_per_pixel() again).

2016-03-24edid: Add helper function to calculate bits-per-pixel dependent valuesJulius Werner
Coreboot and most payloads support three basic pixel widths for the framebuffer. It assumes 32 by default, but several chipsets need to override that value with whatever else they're supporting. Our struct edid contains multiple convenience values that are directly derived from this (and other properties), so changing the bits per pixel always requires recalculating all those dependents in the chipset code. This patch provides a small convenience wrapper that can be used to consistently update the whole struct edid with a new pixel width instead, so we no longer need to duplicate those calculations everywhere. BUG=None TEST=Booted Oak in all three pixel widths (which it conveniently all supports), confirmed that images looked good.

When enabling the IOMMU on certain systems dmesg is spammed with I/O page faults like the following: AMD-Vi: Event logged [IO_PAGE_FAULT device=00:14.0 domain=0x000a address=0x000000fdf9103300 flags=0x0030] Decoding the faulting address: 0x000000fdf9103300 fdf91x Hypertransport system management region 33 SysMgtCmd (System Management Command) = 0x33 3 Base Command Type = 0x3: STPCLK (Stop Clock request) 3 SMAF (System Management Action Field) = [3:1] = 0x1 1 Signal State Bit Map = [0] = 0x1 Therefore, the error appears to be triggered by an upstream C1E request. This was eventually traced to concurrent access to the SP5100's SPI Flash controller by multiple APs during startup. Calls to the nvram read functions get_option and read_option call CBFS functions, which in turn make near-simultaneous requests to the SPI Flash controller, thus placing the SP5100 in an invalid state. This limitation is not documented in any public AMD errata, and was only discovered through considerable debugging effort.

2015-11-20intel: Add MMA feature in corebootPratik Prajapati
This patch implements Memory Margin Analysis feature in coreboot. Few things to note (1) the feature is enabled by setting CONFIG_MMA=y in the config file (2) coreboot reads mma_test_metadata.bin from cbfs during romstage and gets the name of MMA test name and test config name. Then coreboot finds these files in CBFS. If found, coreboot passes location and size of these files to FSP via UPD params. Sets MrcFastBoot to 0 so that MRC happens and then MMA test would be executed during memory init. (3) FSP passes MMA results data in HOB and coreboot saves it in cbmem (4) when system boots to OS after test is executed cbmem tool is used to grab the MMA results data.

Per IRC and Gerrit discussion, the normal / fallback selector code is a rather weak spot in coreboot, and did not function correctly for certain use cases. Rework the selector to more clearly indicate proper operation, and also remove dead code. Also tentatively abandon use of RTC bit 385; a follow-up patch will remove said bit from all affected mainboards. The correct operation of the fallback code selector approximates that of a power line recloser, with a user option to attempt normal boot that can be cleared by firmware, but never set by firmware. Additionally, if cleared by user, the fallback path should always be used on the next reboot.
