Both PCH types are very different, and mixing the code for both together isn't useful. Make `ISLP` return a constant, so that IASL can fold it.

2020-09-14sb/intel/lynxpoint: Do not determine PCH type at runtimeAngel Pons
Both PCH types are very different, and mixing the code for both together isn't useful. First of all, inline `pch_is_lp` to return a constant. This allows the compiler to optimize out unused code, which results in smaller executables. For the Asrock B85M Pro4, it's about 2.5 KiB less. Subsequent commits will further split the southbridge code.

2020-08-29sb/intel/bd82x6x: Factor out common ME functionsAngel Pons
We can now factor out the essentially duplicated ME functions. We include a .c file to preserve reproducibility. This is needed because there are two different `mei_base_address` global variables, and we have to access the same variables in order for builds to be reproducible. The duplicate global in `me.c` and `me_8.x.c` will be completely gone once this new `me_common.c` file becomes a standalone compilation unit. We are wrapping some things in static inline functions, as they won't be directly accessible anymore after moving to a separate compilation unit. Tested with BUILD_TIMELESS=1, Asus P8Z77-V LX2 remains identical.

2020-08-07sb/intel/lynxpoint: Consider root ports being disabled by strapAngel Pons
PCIe RPC (Root Port Configuration) straps will force-disable some root port functions if some root ports have a width greater than x1. In two cases, this affects the last function. The PCIe init code will never finish configuring the root ports if that is the case: it assumes that the last function will eventually run through the code, but it doesn't. If PCIe initialization does not complete, pressing the power button will not power off the board, unless it is held for about five seconds. Also, Windows 10 will show a BSOD about MACHINE CHECK EXCEPTION, and lock up instead of rebooting. Depending on the microcode version, the BSOD may not be visible. This happens even when the root port is not populated. Use the strap fuse configuration value to know which configuration the PCH is strapped to. If needed, update the number of ports accordingly. In addition, print the updated value to ease debugging PCIe init code. Existing code in coreboot disagrees with public documentation about the root port width straps. Assume existing code is correct and document these assumptions in a table, as an explanation for the added code. Tested on Asrock B85M Pro4, PCIe initialization completes successfully.

This code is not even being build-tested. Drop it before it grows moss. Also drop a now-unnecessary #undef directive from one mainboard.

2020-08-03Change all assert(0) to BUG()Julius Werner
I would like to make assertions evaluate at compile time where possible, but sometimes people used a literal assert(0) to force an assertion in a certain code path. We already have BUG() for that so let's just replace those instances with that.

2020-07-28src: Never set ISA Enable on PCI bridgesAngel Pons
Looks like no one really knows what this bit would be useful for, nor when it would need to be set. Especially if coreboot is setting it even on PCI *Express* bridges. Digging through git history, nearly all instances of setting it on PCIe bridges comes from i82801gx, for which no reason was given as to why this would be needed. The other instances in Intel code seem to have been, unsurprisingly, copy-pasted. Drop all uses of this definition and rename it to avoid confusion. The negation in the name could trick people into setting this bit again. Tested on Asrock B85M Pro4, no visible difference.
