2019-03-07prog_loader: Associate TS_END_ROMSTAGE timestamp with postcar if existSubrata Banik
This patch adds timestamp for "end of romstage" with postcar if platform has selected postcar as dedicated stage. If postcar stage doesn't exist then "end of romstage" timestamp will get call while starting of ramstage as exist today. TEST=It's been observed that "end of romstage" timestamp doesn't appear in "cbmem -t" log when ramstage is not getting executed. As part of this fix "end of romstage" timestamp is showing in "cbmem -t" log on Intel platform where POSTCAR is a dedicated stage.

2018-04-24arch/x86/postcar: add comment clarifying reason for finalize_load()Aaron Durbin
Certain platforms need to pass different stack pointer values to postcar depending on S3 resume or not. Add comments to ease the reader in understanding the point. If different stack values weren't needed the program was already cached in stage cache with the correct value.

Stash and reload postcar stage in the stage cache for increased S3 resume speed. It's impact is small (2 ms or so), but there's no need to go to the boot media on resume to reload something that was already loaded. This aligns with the same paths we take on ramstage as well.

2016-09-12arch/x86: Utilize additional MTRRs in postcar_frame_add_mtrrRizwan Qureshi
In the current implementation of postcar_frame_add_mtrr, if provided size is bigger than the base address alignment, the alignment is considered as size and covered by the MTRRs ignoring the specified size. In this case the callee has to make sure that the provided size should be smaller or equal to the base address alignment boundary. To simplify this, utilize additonal MTRRs to cover the entire size specified. We reuse the code from cpu/x86/mtrr/mtrr.c.

The final step of moving the used and max MTRRs on to stack is moved to a new function, that can be used outside of postcar phase.

2016-04-02lib/prog_loading: introduce prog_segment_loaded()Aaron Durbin
In order to not muddle arch vs chipset implementations provide a generic prog_segment_loaded() which calls platform_segment_loaded() and arch_segment_loaded() in that order. This allows the arch variants to live in src/arch while the chipset/platform code can implement their own.

2016-03-23arch/x86: introduce postcar stage/phaseAaron Durbin
Certain chipsets don't have a memory-mapped boot media so their code execution for stages prior to DRAM initialization is backed by SRAM or cache-as-ram. The postcar stage/phase handles the cache-as-ram situation where in order to tear down cache-as-ram one needs to be executing out of a backing store that isn't transient. By current definition, cache-as-ram is volatile and tearing it down leads to its contents disappearing. Therefore provide a shim layer, postcar, that's loaded into memory and executed which does 2 things: 1. Tears down cache-as-ram with a chipset helper function. 2. Loads and runs ramstage. Because those 2 things are executed out of ram there's no issue of the code's backing store while executing the code that tears down cache-as-ram. The current implementation makes no assumption regarding cacheability of the DRAM itself. If the chipset code wishes to cache DRAM for loading of the postcar stage/phase then it's also up to the chipset to handle any coherency issues pertaining to cache-as-ram destruction.
