2022-05-16soc/intel/*: Use SSDT to pass A4GB and A4GSArthur Heymans
GNVS is more fragile as you need to keep struct elements in sync with ASL code.

2022-05-15soc/intel/alderlake: Move array declarationArthur Heymans
Clang does not like array declarations inside plain switch cases. There are 2 options to fix this: use a block inside the switch statement, or declare it outside the switch statement. This does the latter.

2022-05-14soc/intel/alderlake: Fix Coverity CID 1488814Tarun Tuli
CID 1488814:  Uninitialized variables  (UNINIT) Commit c66ea98 introduced an issue after static analysis on merge. Because every APIC is associated with a CPU, this did not result in any issues at runtime but should be fixed/cleaned up. Now, the path name is initialized to null.

2022-05-12soc/intel/alderlake: provide a list of D-states to enter LPMTarun Tuli
Implement sub-function 1 (Get Device Constraints) of the Low Power S0 Idle Device-Specific Method (_DSM). This provides a way in which to describe various devices required D-states to enter LPM (S0ix). The information can be used to help in diagnostics and understanding of S0ix entry failure. Values were derived from Intel document 595644 (rev 0.45) and the ADL FSP sample ASL. This implementation adds support for ADL. Other SoC's could be ported to be included as well. If they aren't, they will default to the existing behavior of a single hardcoded device to ensure compatibility with Windows. TEST=Built and tested on brya by verifying SSDT contents Change-Id: Ibe46a0583c522a8adf0a015cd3a698f694482437 Signed-off-by: Tarun Tuli <taruntuli@google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/63969 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Tim Wawrzynczak <twawrzynczak@chromium.org> Reviewed-by: Lance Zhao

2021-06-28soc/intel: Drop casts around `soc_read_pmc_base()`Angel Pons
The `soc_read_pmc_base()` function returns an `uintptr_t`, which is then casted to a pointer type for use with `read32()` and/or `write32()`. But since commit b324df6a540d154cc9267c0398654f9142aae052 (arch/x86: Provide readXp/writeXp helpers in arch/mmio.h), the `read32p()` and `write32p()` functions live in `arch/mmio.h`. These functions use the `uintptr_t type for the address parameter instead of a pointer type, and using them with the `soc_read_pmc_base()` function allows dropping the casts to pointer.
