2018-05-11acpi: Add support for writing ACPI _PLD structuresDuncan Laurie
This commit adds support for writing ACPI _PLD structures that describe the physical location of a device to the OS. This can be used by any device with a physical connector, but is required when defining USB ports for the OS. A simple function is provided that generates a generic _PLD structure for USB ports based on the USB port type.

2018-05-04lib/bootmem: Add more bootmem tagsPatrick Rudolph
Introduce new bootmem tags to allow more fine grained control over buffer allocation on various platforms. The new tags are: BM_MEM_RAMSTAGE : Memory where any kind of boot firmware resides and that should not be touched by bootmem (by example: stack, TTB, program, ...). BM_MEM_PAYLOAD : Memory where any kind of payload resides and that should not be touched by bootmem. Starting with this commit all bootmem methods will no longer see memory that is used by coreboot as usable RAM. Bootmem changes: * Introduce a weak function to add platform specific memranges. * Mark memory allocated by bootmem as BM_TAG_PAYLOAD. * Assert on failures. * Add _stack and _program as BM_MEM_RAMSTAGE.

2018-04-26arch/x86: allow idt to be available to link in all stagesAaron Durbin
Add Kconfig IDT_IN_EVERY_STAGE to optionally specify having the interrupt handling code available to all stages. In order to do this the idt setup is moved to a C module. The vecX entries are made global so that a table of references to all the interrupt vector entry points can be used to dynamically initialize the idt. The ramification for ramstage is that exceptions are initialized later (lib/hardwaremain.c). Not all stages initialize exceptions when this Kconfig variable is selected, but bootblock for the C, stages using assembly_entry.S, and of course ramstage do. Anything left out just needs a call to exception_init() at the right location.

2018-04-25arch/x86: add support for cache-as-ram pagingAaron Durbin
Processors, such as glk, need to have paging enabled while in cache-as-ram mode because the front end is agressive about fetching lines into the L1I cache. If the line is dirty and in the L1D then it writes it back to "memory". However, in this case there is no backing store so the cache-as-ram data that was written back transforms to all 0xff's when read back in causing corruption. In order to mitigate the failure add x86 architecture support for enabling paging while in cache-as-ram mode. A Kconfig variable, NUM_CAR_PAGE_TABLE_PAGES, determines the number of pages to carve out for page tables within the cache-as-ram region. Additionally, the page directory pointer table is also carved out of cache-as-ram. Both areas are allocated from the persist-across-stages region of cache-as-ram so all stages utilizing cache-as-ram don't corrupt the page tables. The two paging-related areas are loaded by calling paging_enable_for_car() with the names of cbfs files to load the initial paging structures from.

2018-04-12include/memory_info.h: Change serial number field from 5 bytes to 4Raul E Rangel
dimm_info.serial had a strange contract. The SPD spec defines a 4 byte serial number. dimm_info.serial required a 4 character ascii string with a null terminator. This change makes the serial field so it matches the SPD spec. smbios.c will then translate the byte array into hex and set it on the smbios table. There were only two callers that set the serial number: * haswell/raminit.c: already does a memcpy(serial, spd->serial, 4), so it already matches the new contract. * amd_late_init.c: Previously copied the last 4 characters. Requires decoding the serial number into a byte array. google/cyan/spd/spd.c: This could be updated to pass the serial number, but it uses a hard coded spd.bin.

2018-04-01x86: Increase time out for parking APs to 250msFurquan Shaikh
Change f43adf0 (intel/common/block/cpu: Change post_cpus_init after BS_DEV RESOURCES) moved post_cpus_init to BS_OS_RESUME for S3 path. This results in BSP timing out waiting for APs to be parked. This change increases the time out value for APs to be parked to 250ms. This value was chosen after running suspend-resume stress test and capturing the maximum time taken for APs to be parked for 100 iterations. Typical values observed were ~150ms. Maximum value observed was 152ms. BUG=b:76442753 TEST=Verified for 100 iterations that suspend-resume does not run into any AP park time out.
