2021-02-07nb/intel/pineview: Clean up FIXMEs in raminitNico Huber
Using MCHBAR32_AND_OR() in these two cases changes the order of additions slightly. Originally, the MCHBAR offset and the base register offset (0x5a4/0x5b4) were added first. Due to the added parentheses in the register macros, now the complete register offset is calculated first and then added to MCHBAR. Associativity tells us that this doesn't change the result. Changes in the resulting binary were verified manually on the object file.

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.

Command and clock timings always need to be computed, so drop both the nonsensical condition and the equally-worthless corresponding comment.

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.

There are multiple different devicetree setting formats for graphics panel settings present in coreboot. Replace the ones for the platforms that already have (mostly) unified gma/graphics setup code by a unified struct in the gma driver. Hook it up in HSW, BDW, SKL, and APL and adapt the devicetrees accordingly. Always ensure that values don't overflow by applying appropriate masks. The remaining platforms implementing panel settings (GM45, i945, ILK and SNB) can be migrated later after unifying their gma/graphics setup code.

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.
