2016-12-17Revert "arch/x86/smbios: Correct manufacturer ID"Nico Huber
This reverts commit c86da67436827c25919a2f5966049485a58fc984. Alas, I have to disagree with this in every single line. The comment added to the top of the file only applies to a single function therein which sits over a hundred lines below. That's not much helpful. More- over, the link in the comment is already down ofc. The comment is also irritating as it doesn't state in which way (enco- ding!) it applies to the code, which presumably led to the wrong in- terpretation of the IDs. At last, if anything should have changed it is the strings, the IDs are resolved to. `smbios_fill_dimm_manufacturer_from_id()` has to resolve the IDs it gets actually fed and not a random selection from any spec. Since I digged into it, here's why the numbers are correct: The func- tion started with the SPD encoding of DDR3 in mind. There, the lower byte is the number of a "bank" of IDs with an odd-parity in the upper most bit. The upper byte is the ID within the bank. The "correction" was to clear the parity bit for naught. The function was later exten- ded with IDs in the DDR2-SPD encoding (which is actually 64-bit not 16). There, a byte, starting from the lowest, is either an ID below 127 plus odd-parity, or 127 which means look in the next byte/bank. Unused bytes seem to be filled with 0xff, I guess from the 0xff2c.

2016-09-19arch/x86,lib: make cbmem console work in postcar stageAaron Durbin
Implement postcar stage cbmem console support. The postcar stage is more like ramstage in that RAM is already up. Therefore, in order to make the cbmem console reinit flow work one needs the cbmem init hook infrastructure in place and the cbmem recovery called. This call is added to x86/postcar.c to achieve that. Additionally, one needs to provide postcar stage cbmem init hook callbacks for the cbmem console library to use. A few other places need to become postcar stage aware so that the code paths are taken. Lastly, since postcar is backed by ram indicate that to the cbmem backing store.

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.

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>
