2020-08-07sb/intel/lynxpoint: Use PCI bitwise opsAngel Pons
Some cases could not be factored out while keeping reproducibility. Also mark some potential bugs with a FIXME comment, since fixing them while also keeping the binary unchanged is pretty much impossible. Tested with BUILD_TIMELESS=1, Asrock B85M Pro4 does not change.

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.

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.

2020-07-20sb/intel/i82801dx: Drop unneeded PM2 settings from FADTAngel Pons
The PM2_CNT register block is not present on this southbridge, as per Intel Document 290744 (ICH4 datasheet). Also, the ACPI specification, version 6.3, section 4.8.1.3 (PM2 Control Register), says: This register block is optional, if not supported its block pointer and length contain a value of zero. Since the FADT struct defaults to zero in coreboot, we don't need to do anything to indicate PM2_CNT is not supported. So, drop unneeded values. Also delete a comment about `pm2_cnt_len`, which said that the right value differs from zero. Looks like that comment was wrong instead.

2020-07-20src: Drop useless PM1b settings from FADTAngel Pons
None of the currently-supported chips has PM1b_EVT nor PM1b_CNT event register blocks. According to the ACPI specification, version 6.3, sections 4.8.1.1 and 4.8.1.2 (PM1 Event/Control Registers): If the PM1b_EVT_BLK is not supported, its pointer contains a value of zero in the FADT. If the PM1b_CNT_BLK is not supported, its pointer contains a value of zero in the FADT. Since the FADT struct defaults to zero in coreboot, we don't need to do anything with PM1b for now. So, drop unneeded writes to PM1b fields. Tested on Asus P8Z77-V LX2 with Linux 5.7.6 and Windows 10 at the end of the patch train, both operating systems are able to boot successfully.

2020-07-20src: Drop useless GPE1 settings from FADTAngel Pons
None of the currently-supported chips has a GPE1 block. The ACPI spec, version 6.3, section 4.8.1.6 (General-Purpose Event Registers) says: If a generic register block is not supported then its respective block pointer and block length values in the FADT table contain zeros. Since the FADT struct defaults to zero in coreboot, we don't need to do anything with GPE1 for now. So, drop the unneeded writes to GPE1 fields. Tested on Asus P8Z77-V LX2 with Linux 5.7.6 and Windows 10 at the end of the patch train, both operating systems are able to boot successfully.
