2016-10-31lib/prog_loaders: use common ramstage_cache_invalid()Aaron Durbin
All current implementations of ramstage_cache_invalid() were just resetting the system based on the RESET_ON_INVALID_RAMSTAGE_CACHE Kconfig option. Move that behavior to a single implementation within prog_loaders.c which removes duplication.

2016-10-11cpu/intel/smm: Use CONFIG_SMM_TSEG_SIZENico Huber
An epic battle to fix Nehalem finally ended when we found an odd mask set in SMRR. This was caused by a wrong calculation of TSEG size. It was assumed that TSEG spans the whole space between TSEG base and GTT. This is wrong as TSEG base might have been aligned down. TEST: On X201, copied 1GiB from usb key to sd-card and verified.

2016-10-09cpu/intel/model_6ex: Set msr bits for dynamic L2, C2E, C4EArthur Heymans
The datasheets "Intel® Core™ Duo Processor and Intel® Core™ Solo Processor on 65 nm Process" mentions cpu C-states substates which can either be attained by adding a substate hint to the MWAIT/P_LVLx request or automatically by setting some msr bits correctly. This just sets the same msr bits as model_6fx to enable dynamic L2 cache, C2E and C4E acpi cpu states. The result is that when limiting a thinkpad x60 with a yonah T2400 cpu to the acpi cpu C2 state, the idle power usage drops from 18W to 14W. When the lowest C-state is set to C4 the idle power usage seems to remain similar.

2016-09-08Kconfig: Add option for microcode filenamesMartin Roth
Hardcoding the microcode filenames into the makefiles is great when the microcode is in the blobs directory. When the microcode isn't posted to the blobs directory, we need some method of supplying the microcode binary into the build. This can of course be done manually after the build has completed, as can be done with everything that we're including in the ROM image. Instead of making life hard for everyone though, let's just add a way to specify where the microcode rom comes from.

2016-08-18Kconfig: lay groundwork for not assuming SPI flash boot deviceAaron Durbin
Almost all boards and chipsets within the codebase assume or use SPI flash as the boot device. Therefore, provide an option for the boards/chipsets which don't currently support SPI flash as the boot device. The default is to assume SPI flash is the boot device unless otherwise instructed. This falls in line with the current assumptions, but it also allows one to differentiate a platform desiring SPI flash support while it not being the actual boot device. One thing to note is that while google/daisy does boot with SPI flash part no SPI API interfaces were ever implemented. Therefore, mark that board as not having a SPI boot device.

2016-07-22cpu/x86/mtrr: correct variable MTRR calculation around 1MiB boundaryAaron Durbin
The fixed MTRRs cover the range [0:1MiB). While calculating the variable MTRR usage the 1MiB boundary is checked such that an excessive number of MTRRs aren't used because of unnatural alignment at the low end of the physical address space. Howevever, those checks weren't inclusive of the 1MiB boundary. As such a variable MTRR could be used for a range which is actually covered by the fixed MTRRs when the end address is equal to 1MiB. Likewise, if the starting address of the range lands on the 1MiB boundary then more variable MTRRs are calculated in order to meet natural alignment requirements.

Allow the platform to override the input clock for the UART by implementing the routine uart_platform_refclk and setting the Kconfig value UART_OVERRIDE_REFCLK. Provide a default uart_platform_refclk routine which is disabled when UART_OVERRIDE_REFCLK is selected. This works around ROMCC not supporting weak routines.

2016-04-11cpu/x86/tsc: prepare for CAR_GLOBAL in delay_tsc.cAaron Durbin
The current code in delay_tsc.c uses globals and is heavily guarded by a lot of preprocessor macros. In order to remove __PRE_RAM__ constraints one needs to use CAR_GLOBAL for the global variables. Therefore, abstract away direct access to the globals such that CAR_GLOBAL can be easily employed.

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.
