* soc/intel/elkhartlake: Fix PMC read_resources callbackTim Wawrzynczak2022-06-291-1/+1
| | | | | | | | | | | | | The `limit` field for the PMC fixed BAR was incorrectly set to the `base + size + 1`, where it should be `base + size - 1`, to correctly tell the allocator the limit.

* soc/intel/*/pmc: Add `finalize` operation for pmcSubrata Banik2022-02-151-0/+17
| | | | | | | | | | | | | | | | | | | | This patch implements the required operations to perform prior to booting to OS using coreboot native driver when platform decides to skip FSP notify APIs, i.e., Ready to Boot and End Of Firmware. Additionally, move the PMCON status bit clear operation to `.final` ops to cover any such chances where FSP-S Notify Phase or any other later boot stage may request a global reset and PMCON status bit remains set. BUG=b:211954778 TEST=Able to build brya with these changes.

| | | | | | | | | | | Since it's just a one-liner, implement disabling of the ACPI timer in soc code. This reduces complexity.

* soc/intel: move disabling of PM Timer to SoC PMC codeMichael Niewöhner2021-10-171-0/+9
| | | | | | | | | | | | | | | | | | | | Move disabling of PM Timer to SoC PMC code. The original reason for placing that in `finalize` [1] was FSP hanging due to use of the PM timer without enabling timer emulation first in coreboot, which was added later [2].

| | | | | | | | | | | | | | | | Commit 2c26108208e4aa48de21be576ab6cad9286d7934 moved this function to pmutil.c for Tiger Lake. Do this to all other platforms for consistency. For Skylake, __SIMPLE_DEVICE__ preprocessor guards are no longer needed. With this change, pmc.c is only needed in ramstage. Adjust Makefile.inc accordingly, and drop ENV_RAMSTAGE guards from Skylake.
