2020-05-02acpi: Move ACPI table support out of arch/x86 (3/5)Furquan Shaikh
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>

If the default value isn't set this way, Kconfig will add the 0x to the start, and the entry can be added unnecessarily to the defconfig since it's "different" than what was set by the default.

2015-10-14x86: add standalone verstage supportAaron Durbin
To support x86 verstage one needs a working buffer for vboot. That buffer resides in the cache-as-ram region which persists across verstage and romstage. The current assumption is that verstage brings cache-as-ram up and romstage tears cache-as-ram down. The timestamp, cbmem console, and the vboot work buffer are persistent through in both romstage and verstage. The vboot work buffer as well as the cbmem console are permanently destroyed once cache-as-ram is torn down. The timestamp region is migrated. When verstage is enabled the assumption is that _start is the romstage entry point. It's currently expected that the chipset provides the entry point to romstage when verstage is employed. Also, the car_var_*() APIs use direct access when in verstage since its expected verstage does not tear down cache-as-ram. Lastly, supporting files were added to verstage-y such that an x86 verstage will build and link. BUG=chrome-os-partner:44827 BRANCH=None TEST=Built and booted glados using separate verstage.

2015-04-10tpm: Remove error message for unknown resource typeDuncan Laurie
This is being triggered because the base address is added, but there is nothing that needs done with it in set_resources step and the ERROR message is tripping suspend resume test scripts.

2015-04-10tpm: Add ramstage driver and interrupt configurationDuncan Laurie
This adds a ramstage driver for the TPM and allows the interrupt to be configured in devicetree.cb. The interrupt vector is set like other PNP devices, and the interrupt polarity is set with a register configuration variable. These values are written into locality 0 TPM_INT_VECTOR and TPM_INT_ENABLE and then all interrupts are disabled so they are not used in firmware but can be enabled by the OS. It also adds an ACPI device for the TPM which will configure the reported interrupt based on what has been written into the TPM during ramstage. The _STA method returns enabled if CONFIG_LPC_TPM is enabled, and the _CRS method will only report an interrupt if one has been set in the TPM itself. The TPM memory address is added by the driver and declared in the ACPI code. In order to access it in ACPI a Kconfig entry is added for the default TPM TIS 1.2 base address. Note that IO address 0x2e is required to be declared in ACPI for the kernel driver to probe correctly. BUG=chrome-os-partner:33385 BRANCH=samus,auron TEST=manual testing on samus: 1) Add TPM device in devicetree.cb with configured interrupt and ensure that it is functional in the OS. 2) Test with active high and active low, edge triggered and level triggered setups. 3) Ensure that with no device added to devicetree.cb that the TPM is still functional in polling mode.

2015-04-10tpm: Move the LPC TPM driver to a subdirectoryDuncan Laurie
This moves the LPC TPM driver to drivers/pc80/tpm so it can be turned into a ramstage driver with a chip.h It includes no other changes yet.
