2016-05-27arch/x86: provide verstage support for CONFIG_C_ENVIRONMENT_BOOTBLOCKAaron Durbin
When CONFIG_C_ENVIRONMENT_BOOTBLOCK is employed there's no need for a chipset specific verstage entry point because cache-as-ram has already been initialized. Therefore, provide a default entry point for verstage in that environment.

2016-05-26drivers/intel/fsp2_0: Send post codes around calls to the blobsAlexandru Gagniuc
By design, FSP will send POST codes to port 80. In this case we have both coreboot and FSP pushing post codes, which may make debugging harder. In order to get a clear picture of where FSP execution begins and ends, send post codes before and after any call to the FSP blobs. Note that sending a post code both before and after is mostly useful on chromeec enabled boards, where the EC console will provide a historic list of post codes.

Add a new function "gpio_acpi_path()" that can be implemented by SoC/board code to provide a mapping from a "gpio_t" pin to a controller by returning the ACPI path for the controller that owns this particular GPIO. This is implemented separately from the "acpi_name" handler as many SOCs do not have a specific device that handles GPIOs (or may have many devices and the only way to know which is the opaque gpio_t) and the current GPIO library does not have any association with the device tree. If not implemented (many SoCs do not implement the GPIO library abstraction at all in coreboot) then the default handler will return NULL and the caller knows it cannot determine this reliably.

2016-05-21device: Add an ACPI device name and path concept to devicesDuncan Laurie
Add a function to "struct device_operations" to return the ACPI name for the device, and helper functions to find this name (either from the device or its parent) and to build a fully qualified ACPI path from the root device. This addition will allow device drivers to generate their ACPI AML in the SSDT at boot, with customization supplied by devicetree.cb, instead of needing custom DSDT ASL for every mainboard. The root device acpi_name is defined as "\\_SB" and is used to start the path when building a fully qualified name. This requires SOC support to provide handlers for returning the ACPI name for devices that it owns, and those names must match the objects declared in the DSDT. The handler can be done either in each device driver or with a global handler for the entire SOC. Simplified example of how this can be used for an i2c device declared in devicetree.cb with: chip soc/intel/skylake # "\_SB" (from root device) device domain 0 on # "PCI0" device pci 19.2 on # "I2C4" chip drivers/i2c/test0 device i2c 1a.0 on end # "TST0" end end end end And basic SSDT generating code in the device driver: acpigen_write_scope(acpi_device_scope(dev)); acpigen_write_device(acpi_device_name(dev)); acpigen_write_string("_HID", "TEST0000"); acpigen_write_byte("_UID", 0); acpigen_pop_len(); /* device */ acpigen_pop_len(); /* scope */ Will produce this ACPI code: Scope (\_SB.PCI0.I2C4) { Device (TST0) { Name (_HID, "TEST0000") Name (_UID, 0) } } Change-Id: Ie149595aeab96266fa5f006e7934339f0119ac54 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://review.coreboot.org/14840 Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin <adurbin@chromium.org>

2016-05-19lib/timestamp: Do not initialize cache in timestamp_cache_get()Alexandru Gagniuc
timestamp_cache_get() would call timestamp_cache_init() whenever it found a timestamp cache in the TIMESTAMP_CACHE_UNINITIALIZED state. That means that timestamp_cache_get() will never reurn a cache in the uninitialized state. However, timestamp_init() checks against the uninitialized state, as it does not expect timestamp_cache_get() to perform any initialization. As a result, the conditional branch can never be reached. Simply remove the timestamp_cache_init() call from timestamp_cache_get().

2016-05-19arch/x86: Include timestamp.c in all stagesAlexandru Gagniuc
timestamp.c was not included in bootblock and postcar. This means that these two stages would use the weak implementation in lib/timestamp.c instead of the arch-specific implementation based on rdtsc. This resulted in using timer_monotonic_get() which resets the timestamps from 0. timer_monotonic_get() only provides per-stage incrementing semantics on x86 because lapic implementation has counting down values. A globally incrementing counter like rdtsc provides the semantics like every other non-x86. On the test configuration, the weak implementation of timestamp_get() returned zero, resulting in wrong timestamps coming from the bootblock, while romstage and ramstage used the arch implementation and returned correct timestamps. This is a great example of why weak functions are dangerous, and how easy it is to miss subtle yet strong interactions between subsystems and the coreboot buildsystem.
