2022-10-20drivers/tpm: Move TPM init to end of device init phaseMatt DeVillier
Boards which use an I2C TPM and do not use vboot will not have the I2C bus initialized/ready at the start of the device init phase. If TPM init is called before the bus, init will fail with I2C transfer timeouts and a significantly lengthened boot time. Resolves: https://ticket.coreboot.org/issues/429 TEST=build/boot google/reef w/o vboot, verify successful TPM init.

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>

As discussed on the mailing list and voted upon, the coreboot project is going to move the majority of copyrights out of the headers and into an AUTHORS file. This will happen a bit at a time, as we'll be unifying license headers at the same time. Updated Authors file is in a separate commit.

Logic: If vboot is not used and the tpm is not initialized in the romstage makes use of the ramstage driver to initialize the TPM globally without having setup calls in lower SoC level implementations. * Add TPM driver in ramstage chip init which calls the tpm_setup function. * Purge all occurrences of TPM init code and headers. * Only compile TIS drivers into ramstage except for vboot usage. * Remove Google Urara/Rotor TPM support because of missing i2c driver in ramstage.
