* CBMEM: Change declarations for initialization hooksKyösti Mälkki2022-05-201-5/+3
| | | | | | | | | | | | | | | | | | There are efforts to have bootflows that do not follow a traditional bootblock-romstage-postcar-ramstage model. As part of that CBMEM initialisation hooks will need to move from romstage to bootblock. The interface towards platforms and drivers will change to use one of CBMEM_CREATION_HOOK() or CBMEM_READY_HOOK(). Former will only be called in the first stage with CBMEM available.

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.

* acpi_device: Replace polarity with active_low in acpi_gpio for GpioIoFurquan Shaikh2020-07-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* acpi: Move ACPI table support out of arch/x86 (3/5)Furquan Shaikh2020-05-022-6/+6
| | | | | | | | | | | | | | | | | | | | | This change moves all ACPI table support in coreboot currently living under arch/x86 into common code to make it architecture independent. ACPI table generation is not really tied to any architecture and hence it makes sense to move this to its own directory. In order to make it easier to review, this change is being split into multiple CLs. This is change 3/5 which basically is generated by running the following command: $ git grep -iIl "arch/acpi" | xargs sed -i 's/arch\/acpi/acpi\/acpi/g' BUG=b:155428745 Change-Id: I16b1c45d954d6440fb9db1d3710063a47b582eae Signed-off-by: Furquan Shaikh <furquan@google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/40938 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: HAOUAS Elyes <ehaouas@noos.fr>

* rules.h: Rename ENV_VERSTAGE to ENV_SEPARATE_VERSTAGEJulius Werner2020-04-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | 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.
