2016-06-22Ignore RAMTOP for MTRRsKyösti Mälkki
Without RELOCATABLE_RAMSTAGE have WB cache large enough to cover the greatest ramstage needs, as there is no benefit of trying to accurately match the actual need. Choose this to be bottom 16MiB. With RELOCATABLE_RAMSTAGE write-back cache of low ram is only useful for bottom 1MiB of RAM as a small part of this gets used during SMP initialisation before proper MTRR setup.

2016-06-21lpss_i2c: Set SDA hold and support custom speed configDuncan Laurie
This I2C controller has separate registers for different speeds to set specific timing for SCL high and low times, and then a single register to configure the SDA hold time. For the most part these values can be generated based on the freq of the controller clock, which is SOC-specific. The existing driver was generating SCL HCNT/LCNT values, but not the SDA hold time so that is added. Additionally a board may need custom values as the exact timing can depend on trace lengths and the number of devices on the I2C bus. This is a two-part customizaton, the first is to set the values for desired speed for use within firmware, and the second is to provide those values in ACPI for the OS driver to consume. And finally, recent upstream changes to the designware i2c driver in the Linux kernel now support passing custom timing values for high speed and fast-plus speed, so these are now supported as well. Since these custom speed configs will come from devicetree a macro is added to simplify the description: register "i2c[4].speed_config" = "{ LPSS_I2C_SPEED_CONFIG(STANDARD, 432, 507, 30), LPSS_I2C_SPEED_CONFIG(FAST, 72, 160, 30), LPSS_I2C_SPEED_CONFIG(FAST_PLUS, 52, 120, 30), LPSS_I2C_SPEED_CONFIG(HIGH, 38, 90, 30), }" Which will result in the following speed config in \_SB.PCI0.I2C4: Name (SSCN, Package () { 432, 507, 30 }) Name (FMCN, Package () { 72, 160, 30 }) Name (FPCN, Package () { 52, 120, 30 }) Name (HSCN, Package () { 38, 90, 30 }) Change-Id: I18964426bb83fad0c956ad43a36ed9e04f3a66b5 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://review.coreboot.org/15163 Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin <adurbin@chromium.org>

2016-06-09skylake: Support common LPSS I2C driverDuncan Laurie
Support the common Intel LPSS I2C driver for the 6 I2C bus controllers that are present on the Skylake-LP PCH with a 120 mHz clock. The required lpss_i2c_base_address() method is implemented separately for verstage/romstage and ramstage environments. This provides methods to convert to and from "struct device" and the I2C controller bus number for that device. These are used to provide support for the "I2C Bus Operations" that are present in the coreboot devicetree. To support the I2C controller before ramstage an early init function is provided to do minimal initializaiton of the PCI device and assign a temporary base address for use before memory. The final base address is assigned during device enumeration and used during ramstage. Because it is usually not necessary to enable I2C controllers before ramstage a config register for the devicetree is provided to perform early initialization of this controller. In addition the bus speed can be set in the devicetree and that speed will be applied when the device is initialized. If not provided the default speed is set to I2C_SPEED_FAST. This was tested with the google/chell mainboard by reading and writing from the trackpad and codec devices during both verstage and ramstage.

2016-06-09soc/intel/common: Add LPSS I2C driverDuncan Laurie
Add a generic LPSS I2C driver for Intel SOCs that use the Synopsys DesignWare I2C block and have a similar configuration of that block. This driver is ported from the Chromium depthcharge project where it was ported from U-Boot originally, though it looks very different now. From depthcharge it has been modified to fit into the coreboot I2C driver model with platform_i2c_transfer() and use coreboot semantics throughout including the stopwatch API for timeouts. In order for this shared driver to work the SOC must: 1) Define CONFIG_SOC_INTEL_COMMON_LPSS_I2C_CLOCK_MHZ to set the clock speed that the I2C controller core is running at. 2) Define the lpss_i2c_base_address() function to return the base address for the specified bus. This could be either done by looking up the PCI device or a static table if the controllers are not PCI devices and just have a static base address. The driver is usable in verstage/romstage/ramstage, though it does require early initialization of the controller to set a temporary base address if it is used outside of ramstage. This has been tested on Broadwell and Skylake SOCs in both pre-RAM and ramstage environments by reading and writing both single bytes across multiple segments as well as large blocks of data at once and with different configured bus speeds. While it does need specific configuration for each SOC this driver should be able to work on all Intel SOCs currently in src/soc/intel.

Add a PCI driver for the skylake SD card device and have it generate an entry in the SSDT for the card detect GPIO if it is provided by the mainboard in devicetree. This sets up a card detect GPIO configuration that will trigger an interrupt on both edges with a 100ms debounce timeout and can wake the SD controller from D3 state. The GpioInt() entry is bound to the "cd-gpio" device property which will be consumed by the kernel driver. The resulting ACPI output in the SSDT will be combined with the SDXC device declaration in the DSDT. Example: Scope (\_SB.PCI0.SDXC) { Name (_CRS, ResourceTemplate () { GpioInt (Edge, ActiveBoth, SharedAndWake, PullNone, 10000, "\\_SB.PCI0.GPIO", 0, ResourceConsumer) { 35 } }) Name (_DSD, Package () { ToUUID ("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"), Package () { Package () { "cd-gpio", Package () { \_SB.PCI0.SDXC, 0, 0, 1 } } } }) } Change-Id: Ie4c1bfadd962cf55a987edb9ef86e92174205770 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://review.coreboot.org/14995 Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin <adurbin@chromium.org>

2016-05-23soc/intel/apollolake: add support for writing logical boot partition 2Aaron Durbin
On apollolake the boot media layout is different in that the traditional "BIOS" region contains another data structure with the boot assets such as CSE firmware, PMC microcode, CPU microcode, and boot firmware to name a few. There's also a sort of recovery mechanism where there is a second data structure with similar contents halfway through the "BIOS" region. This second structure is referred as the logical boot partition 2 (LBP2), and it's optionally employed. Add support for writing the LBP2 to a specified FMAP region to accommodate platforms which require it.

Add a handler for the Intel Skylake SOC to return the ACPI path for GPIOs. Since all GPIOs are handled by the same controller they all have the same ACPI path and this is a simple handler that just returns a pointer to the GPIO device that is defined in the DSDT.

2016-05-21skylake: Add ACPI device name handlerDuncan Laurie
Add a global ACPI device name handler for the Skylake SOC that will translate skylake device paths into an ACPI path that matches the device objects delcared in the DSDT at soc/intel/skylake/acpi/*. The skylake implementation uses a global acpi_name handler for the SOC and it is not necessary to add a function to every device. This function is used by device drivers calling acpi_device_name() and acpi_device_path() to generate ACPI AML in the SSDT.

We have a timestamp from before cache-as-ram setup saved in the MMX registers. Recover that timestamp, and use it as the base timestamp rather than letting lib/bootblock.c use a late timestamp. This allows more accurate profiling of the boot flow, since CAR setup time is no longer excluded from the timing information.
