2021-05-06src: Retype option API to use unsigned integersAngel Pons
The CMOS option system does not support negative integers. Thus, retype and rename the option API functions to reflect this.

2021-04-05nb/intel/sandybridge: Drop `pci_mmio_size`Angel Pons
There's no good reason to use values smaller than 2 GiB here. Well, it increases available DRAM in 32-bit space. However, as this is a 64-bit platform, it's highly unlikely that 32-bit limitations would cause any issues anymore. It's more likely to have the allocator give up because memory-mapped resources in 32-bit space don't fit within the specified MMIO size, which can easily occur when using a discrete graphics card.

2021-01-15nb/intel/sandybridge: Clarify command timing calculationAngel Pons
Command timing is the absolute value of the most negative `pi_coding` value across all ranks, or zero if there are no negative values. Use the MAX() macro to ease proving that `cmd_delay` can never be negative, and then drop the always-false underflow check. The variable type for `cmd_delay` still needs to be signed because of the comparisons with `pi_coding`, which is a signed value. Using an unsigned type would result in undefined and also undesired behavior.

2021-01-15nb/intel/sandybridge: Fix handling of clock timingAngel Pons
Clock is a differential signal and propagates faster than command and control, therefore its timing needs to be offset with `pi_code_offset`. It is also a periodic signal, so it can safely wrap around. To avoid potential undefined behavior, make `clk_delay` signed. It makes no difference with valid values, because the initial value can be proven to never be negative and `pi_code_offset` is always positive. With this change, it is possible to add an underflow check, for additional sanity.

2021-01-06nb/intel/sandybridge: Define and use `QCLK_PI` constantAngel Pons
To allow adjusting the phase shift of the various I/O signals, the memory controller contains several PIs (Phase Interpolators). These devices subdivide a QCLK (quarter of a clock cycle) in 64 `ticks`, and the desired phase shift is specified in a register. For shifts larger than one QCLK, there are `logic delay` registers, which allow shifting a whole number of QCLKs in addition to the PI phase shift. The number of PI ticks in a QCLK is often used in raminit calculations. Define the `QCLK_PI` macro and use it in place of magic numbers. In addition, add macros for other commonly-used values that use `QCLK_PI` to avoid unnecessarily repeating `2 * QCLK_PI`, such as `CCC_MAX_PI`. Tested with BUILD_TIMELESS=1, Asus P8Z77-V LX2 does not change.

2020-12-30drivers/intel/gma: Include gfx.asl by default for all platforms...Matt DeVillier
which select INTEL_GMA_ACPI. Rework brightness level includes and platform-level asl files to avoid duplicate device definition for GFX0. Include gfx.asl for Skylake/Kabylake, since all other soc/intel/common platforms already do. Adjust mb/51nb/x210 to prevent device redefinition. Some OSes (e.g. Windows, MacOS) require/prefer the ACPI device for the IGD to exist, even if ACPI brightness controls are not utilized. This change adds a GFX0 ACPI device for all boards whose platforms select INTEL_GMA_ACPI without requiring non-functional brightness controls to be added at the board level.

2020-12-25nb/intel/sandybridge: Allow to ignore XMP voltageAngel Pons
Native raminit only supports 1.5V operation, but there are DIMMs which request 1.65V operation in XMP profiles. Add an option to force XMP to be used when the requested voltage isn't supported, which will run the DIMMs at 1.5V with XMP timings. Consider this to be overclocking.
