2020-11-09drivers/usb/acpi: Add support for privacy_gpioRicardo Ribalda
Some devices, such as cameras, can implement a physical switch to disable the input on demand. Think of it like the typical privacy sticker on the notebooks, but more elegant. In order to notify the system about the status this feature, a GPIO is typically used. The map between a GPIO and the feature is done via ACPI, the same way as the reset_gpio works. This patch implements an extra field for the described privacy gpio. This gpio does not require any extra handling from the power management.

2020-11-09driver/usb/acpi: Add power resources for devices on USB portsKarthikeyan Ramasubramanian
Allow a USB device to define PowerResource in its SSDT AML code. PowerResouce ACPI generation expects SoC to define the callbacks for generating AML code for GPIO manipulation. Device requiring PowerResource needs to define following parameters: * Reset GPIO - Optional, GPIO to put device into reset or take it out of reset. * Reset delay - Delay after reset GPIO is asserted (default 0). * Reset off delay - Delay after reset GPIO is de-asserted (default 0). * Enable GPIO - Optional, GPIO to enable device. * Enable delay - Delay after enable GPIO is asserted (default 0). * Enable off delay - Delay after enable GPIO is de-asserted (default 0). BUG=b:163100335 TEST=Ensure that the Power Resource ACPI object is added under the concerned USB device.

2020-07-02acpi_device: Replace polarity with active_low in acpi_gpio for GpioIoFurquan Shaikh
As per ACPI spec, GpioIo does not have any polarity associated with it. Linux kernel uses `active_low` argument within GPIO _DSD property to allow BIOS to indicate if the corresponding GPIO should be treated as active low. Thus, if GPIO has active high polarity or if it does not have any polarity associated with it, then the `active_low` argument is supposed to be set to 0. Having a `polarity` field in acpi_gpio seems confusing because GPIOs might not always have polarity associated with them. Example, in case of DMIC-select GPIO where 0 means select DMIC0 and 1 means select DMIC1, there is no polarity associated with the GPIO. Thus, it would be clearer for mainboard to use macros without having to specify a particular polarity. In order to enable mainboards to provide GPIO information without polarity for GpioIo usage, this change also adds `ACPI_GPIO_OUTPUT` and `ACPI_GPIO_INPUT` macros.

2020-04-23rules.h: Rename ENV_VERSTAGE to ENV_SEPARATE_VERSTAGEJulius Werner
When CONFIG_SEPARATE_VERSTAGE=n, all verstage code gets linked into the appropriate calling stage (bootblock or romstage). This means that ENV_VERSTAGE is actually 0, and instead ENV_BOOTBLOCK or ENV_ROMSTAGE are 1. This keeps tripping up people who are just trying to write a simple "are we in verstage (i.e. wherever the vboot init logic runs)" check, e.g. for TPM init functions which may run in "verstage" or ramstage depending on whether vboot is enabled. Those checks will not work as intended for CONFIG_SEPARATE_VERSTAGE=n. This patch renames ENV_VERSTAGE to ENV_SEPARATE_VERSTAGE to try to clarify that this macro can really only be used to check whether code is running in a *separate* verstage, and clue people in that they may need to cover the linked-in verstage case as well.

This change pulls the group information into a separate structure that can be defined in devicetree. This makes it easier to set for USB devices in devicetree that do not need a full custom PLD. This was tested on a sarien board with the USB devices defined by verifying that the USB 2/3 ports are correctly identified with their peer in sysfs.

2017-09-14usbdebug: Fix init and add support for postcarKyösti Mälkki
It was originally designed such that if usbdebug_init() was called before cbmem_initialize(), it would fetch the already-initialized state from CBMEM. This changed when cbmem_find() behaviour changed to require cbmem_initialize() to be called first. As a result, ramstage had to reinitialize all of the EHCI controller and USB endpoints on entry. This was slow, specially with AMD hardware where one can scan USB ports to probe for the debug dongle. For postcar and ramstage, move usbdebug entry such that it is triggered from CBMEM_INIT_HOOK instead of console_init(). Side-effect of this is usbdebug console shows 'coreboot-xxx ... starting...' line only for romstage. Initialisation for usbdebug is never done in postcar. If you have USBDEBUG_IN_ROMSTAGE=n, postcar will not have console output on usb either. While at it, fix also some other __PRE_RAM__ cases to ENV_ROMSTAGE and alike.

2015-06-09cbmem: Unify CBMEM init tasks with CBMEM_INIT_HOOK() APIKyösti Mälkki
Squashed and adjusted two changes from chromium.git. Covers CBMEM init for ROMTAGE and RAMSTAGE. cbmem: Unify random on-CBMEM-init tasks under common CBMEM_INIT_HOOK() API There are several use cases for performing a certain task when CBMEM is first set up (usually to migrate some data into it that was previously kept in BSS/SRAM/hammerspace), and unfortunately we handle each of them differently: timestamp migration is called explicitly from cbmem_initialize(), certain x86-chipset-specific tasks use the CAR_MIGRATION() macro to register a hook, and the CBMEM console is migrated through a direct call from romstage (on non-x86 and SandyBridge boards). This patch decouples the CAR_MIGRATION() hook mechanism from cache-as-RAM and rechristens it to CBMEM_INIT_HOOK(), which is a clearer description of what it really does. All of the above use cases are ported to this new, consistent model, allowing us to have one less line of boilerplate in non-CAR romstages. BRANCH=None BUG=None TEST=Built and booted on Nyan_Blaze and Falco with and without CONFIG_CBMEM_CONSOLE. Confirmed that 'cbmem -c' shows the full log after boot (and the resume log after S3 resume on Falco). Compiled for Parrot, Stout and Lumpy.

Oops. This patch fixes the issue by extending the CBMEM_INIT_HOOK() mechanism to the cbmem_initialize() call in ramstage. The macro is split into explicit ROMSTAGE_/RAMSTAGE_ versions to make the behavior as clear as possible and prevent surprises (although just using a single macro and relying on the Makefiles to link an object into all appropriate stages would also work). This allows us to get rid of the explicit cbmemc_reinit() in ramstage (which I somehow accounted for in the last patch without realizing that timestamps work exactly the same way...), and replace the older and less flexible cbmem_arch_init() mechanism. Also added a size assertion for the pre-RAM CBMEM console to memlayout that could prevent a very unlikely buffer overflow I just noticed. BRANCH=None BUG=None TEST=Booted on Pinky and Falco, confirmed that ramstage timestamps once again show up. Compile-tested for Rambi and Samus.
