2018-11-23soc/intel/common: Bring DISPLAY_MTRRS into the lightNico Huber
Initially, I wanted to move only the Kconfig DISPLAY_MTRRS into the "Debug" menu. It turned out, though, that the code looks rather generic. No need to hide it in soc/intel/. To not bloat src/Kconfig up any further, start a new `Kconfig.debug` hierarchy just for debug options. If somebody wants to review the code if it's 100% generic, we could even get rid of HAVE_DISPLAY_MTRRS.

2018-10-22intel: Use CF9 reset (part 2)Patrick Rudolph
Make use of the common CF9 reset in SOC_INTEL_COMMON_RESET. Also implement board_reset() as a "full reset" (aka. cold reset) as that is what was used here for hard_reset(). Drop soc_reset_prepare() thereby, as it was only used for APL. Also, move the global-reset logic. We leave some comments to remind us that a system_reset() should be enough, where a full_reset() is called now (to retain current behaviour) and looks suspicious. Note, as no global_reset() is implemented for Denverton-NS, we halt there now instead of issuing a non-global reset. This seems safer; a non-global reset might result in a reset loop.

2018-06-28smm: Add canary to end of stack and die() if a stack overflow occursRaul E Rangel
If CPU 0's stack grows to large, it will overflow into CPU 1's stack. If CPU 0 is handling the interrupt then CPU 1 should be in an idle loop. When the stack overflow occurs it will override the return pointer for CPU 1, so when CPU 0 unlocks the SMI lock, CPU 1 will attempt to return to a random address. This method is not foolproof. If code allocates some stack variables that overlap with the canary, and if the variables are never set, then the canary will not be overwritten, but it will have been skipped. We could mitigate this by adding a larger canary value if we wanted. I chose to use the stack bottom pointer value as the canary value because: * It will change per CPU stack. * Doesn't require hard coding a value that must be shared between the .S and .c. * Passing the expected canary value as a parameter felt like overkill. We can explore adding other methods of signaling that a stack overflow had occurred in a follow up. I limited die() to debug only because otherwise it would be very hard to track down. TEST=built on grunt with a small and large stack size. Then verified that one causes a stack overflow and the other does not.

2018-04-26arch/x86: print cr2 value on every exceptionAaron Durbin
Even though most x86 systems don't run with paging on, it's helpful to always print it out for the ones that do without making a more complicated handler.

2018-04-26cpu/x86: add limited runtime identity page mappingAaron Durbin
When employing PAGING_IN_CACHE_AS_RAM more areas need to be mapped in at runtime. Therefore, paging_identity_map_addr() is added to support adding identity mappings. Because there are a fixed amount of pages in cache-as-ram paging only the existing paging structures can be used. As such that's a limitation on what regions and length one can map. Using util/x86/x86_page_tables.go to generate page tables will always populate all the page directory pages. Therefore, 2MiB mappings are easy to map in.

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.

2018-02-16x86/mtrr: Enable Rd/WrDram mod in AMD fixed MTRRsMarshall Dawson
AMD's fixed MTRRs have RdDram and WrDram bits that route memory accesses to DRAM vs. MMIO. These are typically hidden for normal operation by clearing SYS_CFG[19] (MtrrFixDramModEn). According to BKDGs and AMD64 Programmer's Manual vol 2, this bit is clear at reset, should be set for configuration during POST, then cleared for normal operation. Attempting to modify the RdDram and WrDram settings without unhiding them causes a General Protection Fault. Add functions to enable and disable MtrrFixDramModEn. Unhide/hide as necessary when copying or writing the fixed MTRRs. Finally, modify sipi_vector.S to enable the bits prior to writing the fixed MTRRs and disable when complete. This functionality is compiled out on non-AMD platforms.

The normal AP startup path didn't need this mapping because it was whoever won the race got the next cpu number. Instead of statically calculating (and wrong) just initialize the default APIC id map when the APs come online. Once the APs are online the SMM handler is loaded and the mapping is utilized.
