The API called to write the name of the child table in the dp entry (type ACPI_DP_TYPE_CHILD) was not including the quotes, e.g., it was DAAD and not "DAAD". Thus, the kernel driver did not get the right information from SSDT. Change the API to acpigen_write_string() to fix the issue.

2016-07-08acpi: Change device properties to work as a treeDuncan Laurie
There is a second ACPI _DSD document from the UEFI Forum that details how _DSD style tables can be nested, creating a tree of similarly formatted tables. This document is linked from acpi_device.h. In order to support this the device property interface needs to be more flexible and build up a tree of properties to write all entries at once instead of writing each entry as it is generated. In the end this is a more flexible solution that can support drivers that need child tables like the DA7219 codec, while only requiring minor changes to the existing drivers that use the device property interface. This was tested on reef (apollolake) and chell (skylake) boards to ensure that there was no change in the generated SSDT AML.

2016-05-28acpi_device: Add support for writing ACPI Device PropertiesDuncan Laurie
The recent ACPI specification extensions have formally defined a method for describing device information with a key=value format that is modeled after the Devicetree/DTS format using a special crafted object named _DSD with a specific UUID for this format. There are three defined Device Property types: Integers, Strings, and References. It is also possible to have arrays of these properties under one key=value pair. Strings and References are both represented as character arrays but result in different generated ACPI OpCodes. Various helpers are provided for writing the Device Property header (to fill in the object name and UUID) and footer (to fill in the property count and device length values) as well as for writing the different Device Property types. A specific helper is provided for writing the defined GPIO binding Device Property that is used to allow GPIOs to be referred to by name rather than resource index. This is all documented in the _DSD Device Properties UUID document: http://uefi.org/sites/default/files/resources/_DSD-device-properties-UUID.pdf This will be used by device drivers to provide device properties that are consumed by the operating system. Devicetree bindings are often described in the linux kernel at Documentation/devicetree/bindings/ A sample driver here has an input GPIO that it needs to describe to the kernel driver: chip.h: struct drivers_generic_sample_config { struct acpi_gpio mode_gpio; }; sample.c: static void acpi_fill_ssdt_generator(struct device *dev) { struct drivers_generic_sample_config *config = dev->chip_info; const char *path = acpi_device_path(dev); ... acpi_device_write_gpio(&config->mode_gpio); ... acpi_dp_write_header(); acpi_dp_write_gpio("mode-gpio", path, 0, 0, 0); acpi_dp_write_footer(); ... } devicetree.cb: device pci 1f.0 on chip drivers/generic/sample register "mode_gpio" = "ACPI_GPIO_INPUT(GPP_B1)" device generic 0 on end end end SSDT.dsl: Name (_CRS, ResourceTemplate () { GpioIo (Exclusive, PullDefault, 0, 0, IoRestrictionInputOnly, "\\_SB.PCI0.GPIO", 0, ResourceConsumer) { 25 } }) Name (_DSD, Package () { ToUUID ("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"), Package () { Package () {"mode-gpio", Package () { \_SB.PCI0.LPCB, 0, 0, 1 }} } }) Change-Id: I93ffd09e59d05c09e38693e221a87085469be3ad Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://review.coreboot.org/14937 Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin <adurbin@chromium.org>

2016-05-28acpi_device: Add support for writing ACPI GPIO descriptorsDuncan Laurie
Add definitions to describe GPIOs in generated ACPI objects and a method to write a GpioIo() or GpioInt() descriptor to the SSDT. ACPI GPIOs have many possible configuration options and a structure is created to describe it accurately in ACPI terms. There are many shared descriptor fields between GpioIo() and GpioInt() so the same function can write both types. GpioInt shares many properties with ACPI Interrupts and the same types are re-used here where possible. One addition is that GpioInt can be configured to trigger on both low and high edge transitions. One descriptor can describe multiple GPIO pins (limited to 8 in this implementation) that all share configuration and controller and are used by the same device scope. Accurately referring to the GPIO controller that this pin is connected to requires the SoC/board to implement a function handler for acpi_gpio_path(), or for the caller to provide this directly as a string in the acpi_gpio->reference variable. This will get used by device drivers to describe their resources in the SSDT. Here is a sample for a Maxim 98357A I2S codec which has a GPIO for power and channel selection called "sdmode". chip.h: struct drivers_generic_max98357a_config { struct acpi_gpio sdmode_gpio; }; max98357a.c: void acpi_fill_ssdt_generator(struct device *dev) { struct drivers_generic_max98357a_config *config = dev->chip_info; ... acpi_device_write_gpio(&config->sdmode_gpio); ... } devicetree.cb: device pci 1f.3 on chip drivers/generic/max98357a register "sdmode_gpio" = "ACPI_GPIO_OUTPUT(GPP_C5)" device generic 0 on end end end SSDT.dsl: GpioIo (Exclusive, PullDefault, 0, 0, IoRestrictionOutputOnly, "\\_SB.PCI0.GPIO", 0, ResourceConsumer, ,) { 53 } Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Change-Id: Ibf5bab9c4bf6f21252373fb013e78f872550b167 Reviewed-on: https://review.coreboot.org/14934 Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin <adurbin@chromium.org>

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>

2016-05-19arch/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.

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.

2016-01-30arch/x86: Implement minimal bootblock for C_ENVIRONMENT_BOTOBLOCKAlexandru Gagniuc
Some newer x86 systems can boot from non-memory-mapped boot media (e.g. EMMC). The bootblock may be backed by small amounts of SRAM, or other memory, similar to how most ARM chipsets work. In such cases, we may not have enough code space for romstage very early on. This means that CAR setup and early boot media (e.g. SPI, EMMC) drivers need to be implemented within the limited amount memory of storage available. Since the reset vector has to be contained in this early code memory, the bootblock is the best place to implement loading of other stages. Implement a bootblock which does the minimal initialization, up to, and including switch to protected mode. This then transfers control to platform-specific code. No stack is needed, and control is transferred via a "jmp" such that no stack operations are involved.
