2022-03-08timestamps: Rename timestamps to make names more consistentJakub Czapiga
This patch aims to make timestamps more consistent in naming, to follow one pattern. Until now there were many naming patterns: - TS_START_*/TS_END_* - TS_BEFORE_*/TS_AFTER_* - TS_*_START/TS_*_END This change also aims to indicate, that these timestamps can be used to create time-ranges, e.g. from TS_BOOTBLOCK_START to TS_BOOTBLOCK_END.

This reverts commit 4447996cc582d2c8745802b84b1f5a635e33a22a. It looks like the patch repurposed the `memory_reserved_for_heci_mb` variable as an indicator if the ME firmware is fine. The change to setup_heci_uma() made it bail out early, even though the implementation is obviously prepared to set things up even if the requested UMA size is 0. This also leaves the code in an inconsistent state: The second if's condition is always true.

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.

2020-10-24nb/intel/ironlake: Add more host bridge PCI IDsAngel Pons
The host bridge PCI device ID can be changed by the firmware. There is no documentation about it, though. There's 'official' IDs, which appear in spec updates and Windows drivers, and 'mysterious' IDs, which Intel doesn't want OSes to know about and thus are not listed. The current coreboot code seems to be able to change the device ID of the host bridge, but it seems to be missing a warm reset so that the device ID changes. Account for the 'mysterious' device IDs in the northbridge driver, so that booting an OS has a chance to work. For the sake of completeness, add the PCI device IDs for Clarkdale. Although only Arrandale is known to work, both of them are Ironlake. It is possible that the Management Engine handles changing the PCI device ID, which would not happen when using a broken ME firmware.

This fixes commit e1d1fe454cf27d6b1c2ef5625f1cefc1a9c6ec9d initialize 'reply.command'. The compiler now optimized away the final condition, that checks the result of heci message, resulting in a binary that always calls die(). Fix that behaviour by using volatile.

2020-08-24mrc_cache: Add mrc_cache fetch functions to support non-x86 platformsShelley Chen
Create two new functions to fetch mrc_cache data (replacing mrc_cache_get_current): - mrc_cache_load_current: fetches the mrc_cache data and drops it into the given buffer. This is useful for ARM platforms where the mmap operation is very expensive. - mrc_cache_mmap_leak: fetch the mrc_cache data and puts it into a given buffer. This is useful for platforms where the mmap operation is a no-op (like x86 platforms). As the name mentions, we are not freeing the memory that we allocated with the mmap, so it is the caller's responsibility to do so. Additionally, we are replacing mrc_cache_latest with mrc_cache_get_latest_slot_info, which does not check the validity of the data when retrieving the current mrc_cache slot. This allows the caller some flexibility in deciding where they want the mrc_cache data stored (either in an mmaped region or at a given address). BUG=b:150502246 BRANCH=None TEST=Testing on a nami (x86) device: reboot from ec console. Make sure memory training happens. reboot from ec console. Make sure that we don't do training again.
