2021-01-18ACPI: Refactor ChromeOS specific ACPI GNVSKyösti Mälkki
The layout of GNVS has expectation for a fixed size array for chromeos_acpi_t. This allows us to reduce the exposure of <chromeos/gnvs.h>. If chromeos_acpi_t was the last entry in struct global_nvs padding at the end is also removed. If device_nvs_t exists, place a properly sized reserve for chromeos_acpi_t in the middle.

The S3/S4 workaround is specific to Panther Point stepping A0, and it is wrongly implemented. Rewrite the whole function as per reference code. Since this runs in SMM, be overly cautious and double-check everything. Do not rely on GNVS to determine if xHCI is enabled. Instead, check whether the corresponding bit in the Function Disable register is set. Only Panther Point has xHCI, so exit early if this is not the case.

2021-01-08cbfstool: Use flock() when accessing CBFS filesJulius Werner
Trying to do multiple operations on the same CBFS image at the same time likely leads to data corruption. For this reason, add BSD advisory file locking (flock()) to cbfstool (and ifittool which is using the same file I/O library), so that only one process will operate on the same file at the same time and the others will wait in line. This should help resolve parallel build issues with the INTERMEDIATE target on certain platforms. Unfortunately, some platforms use the INTERMEDIATE target to do a direct dd into the CBFS image. This should generally be discouraged and future platforms should aim to clearly deliminate regions that need to be written directly by platform scripts with custom FMAP sections, so that they can be written with `cbfstool write`. For the time being, update the legacy platforms that do this with explicit calls to the `flock` utility.

2020-12-10sb/intel/bd82x6x: Make me_common.c a compilation unitAngel Pons
We need to make most things non-static so that the code builds. Also, we need to update ibexpeak as well, because it borrows files from bd82x6x. Tested on Asus P8Z77-V LX2, still boots.

2020-12-07sb/intel/common: Modify CONFIG_LOCK_MANAGEMENT_ENGINE behaviorSridhar Siricilla
The patch modifies KConfig behaviour if CSE Lite SKU is integrated into the coreboot. When the CSE Lite SKU is integrated, the KConfig prevents writing to ME region but keeps read access enabled. Since CSE Lite driver checks the signature of RW partition to identify the interrupted CSE firmware update, so host must have read access to the ME region. Also, the patch modifies the KConfig's help text to reflect the change. When CSE Lite SKU is integrated, master access permissions: FLMSTR1: 0x002007ff (Host CPU/BIOS) EC Region Write Access: disabled Platform Data Region Write Access: disabled GbE Region Write Access: disabled Intel ME Region Write Access: disabled Host CPU/BIOS Region Write Access: enabled Flash Descriptor Write Access: disabled EC Region Read Access: disabled Platform Data Region Read Access: disabled GbE Region Read Access: disabled Intel ME Region Read Access: enabled Host CPU/BIOS Region Read Access: enabled Flash Descriptor Read Access: enabled BUG=b:174118018 TEST=Built and verified the access permissions.
