2018-08-01nb/intel/sandybridge: Don't use PCI operations on the pci_domain deviceArthur Heymans
pci ops happen to work on this struct device since the device_path is an union. This patch still keeps adding the fixed resources in the pci_domain ops since moving it to the PCI ops which could properly use the function argument for PCI operations would require all PCI IDs to be added or else breakages are to be expected.

2018-07-30nb/intel/gm45: Use common code for SMM in TSEGArthur Heymans
This makes i82801ix use the common smm southbridge code to set up smm relocation and smi handler setup. This is needed in this change for the the smm relocation code relies on some southbridge functions provided in the common code. Some of the old code is kept for the Q35 qemu target. This also caches the TSEG region and therefore increases MTRR usage a little in some cases. Currently SMRR msr's are not set on model_1067x and model_6fx since this needs the MSRR enable bit and lock set in IA32_FEATURE_CONTROL. This will be handled properly in the subsequent parallel mp init patchset. Tested on Thinkpad X200: boots and going to and resuming from S3 still works fine.

This reverts commit 0e06f5bd70b45fd330d8dfb1dc77cce043caf841. It breaks gm45 and also does some magic without being asked too. It disables bridge devices permanently if no device was found on the se- condary bus. In a simple notebook world this might be ok, but it breaks hot-plugging and late detection (if a secondary bus device comes up too slow for the firmware to detect and the OS has to enumerate it).

2014-02-25Remove CACHE_ROM.Vladimir Serbinenko
With the recent improvement 3d6ffe76f8a505c2dff5d5c6146da3d63dad6e82, speedup by CACHE_ROM is reduced a lot. On the other hand this makes coreboot run out of MTRRs depending on system configuration, hence screwing up I/O access and cache coherency in worst cases. CACHE_ROM requires the user to sanity check their boot output because the feature is brittle. The working configuration is dependent on I/O hole size, ram size, and chipset. Because of this the current implementation can leave a system configured in an inconsistent state leading to unexpected results such as poor performance and/or inconsistent cache-coherency Remove this as a buggy feature until we figure out how to do it properly if necessary.

2013-07-10Fix MMCONF_SUPPORT_DEFAULT for ramstageKyösti Mälkki
Define at one place whether to use IO 0xcf8/0xcfc or MMIO via MMCONF_BASE_ADDRESS for PCI configuration access funtions in ramstage. The implementation of pci_default_config() always returned with pci_cf8_conf1. This means any PCI configuration access that did not target bus 0 used PCI IO config operations, if PCI MMIO config was not explicitly requested.

2013-03-23resources: introduce reserved_ram_resource()Aaron Durbin
mmio_resource() was previously being used for reserving RAM from the OS by using IORESOURCE_IGNORE_MTRR atrribute. Instead, be more explicit for those uses with reserved_ram_resource(). bad_ram_resource() now calls reserved_ram_resource(). Those resources are marked as cacheable but reserved. The sandybridge and haswell code were relying on the implementation fo the MTRR algorithm's interaction for reserved regions. Instead be explicit about what ranges are MMIO reserved and what are RAM reserved.
