2017-09-08soc/intel/common/block: Common ACPIShaunak Saha
This patch adds the common acpi code.ACPI code is very similar accross different intel chipsets.This patch is an effort to move those code in common place so that it can be shared accross different intel platforms instead of duplicating for each platform. We are removing the common acpi files in src/soc/intel/common. This removes the acpi.c file which was previously in src/soc/common/acpi. The config for common acpi is SOC_INTEL_COMMON_BLOCK_ACPI which can be defined in SOC's Kconfig file in order to use the common ACPI code. This patch also includes the changes in APL platform to use the common ACPI block. TEST= Tested the patch as below: 1.Builds and system boots up with the patch. 2.Check all the ACPI tables are present in /sys/firmware/acpi/tables 3.Check SCI's are properly working as we are modifying the function to override madt. 4.Extract acpi tables like DSDT,APIC, FACP, FACS and decompile the by iasl and compare with good known tables. 5.Execute the extracted tables in aciexec to check acpi methods are working properly.

Clang complains about these being missing as Clang is somewhat more strict about the spec than GNU/GCC is. An advantage here is that a different entry-point type-signature shall now be warned about at compile time.

2014-01-16cpu/intel: Make all Intel CPUs load microcode from CBFSAlexandru Gagniuc
The sequence to inject microcode updates is virtually the same for all Intel CPUs. The same function is used to inject the update in both CBFS and hardcoded cases, and in both of these cases, the microcode resides in the ROM. This should be a safe change across the board. The function which loaded compiled-in microcode is also removed here in order to prevent it from being used in the future. The dummy terminators from microcode need to be removed if this change is to work when generating microcode from several microcode_blob.c files, as is the case for older socketed CPUs. Removal of dummy terminators is done in a subsequent patch.

2013-03-19intel microcode: split up microcode loading stagesAaron Durbin
This patch only applies to CONFIG_MICROCODE_IN_CBFS. The intel microcode update routine would always walk the CBFS for the microcode file. Then it would loop through the whole file looking for a match then load the microcode. This process was maintained for intel_update_microcode_from_cbfs(), however 2 new functions were exported: 1. const void *intel_microcode_find(void) 2. void intel_microcode_load_unlocked(const void *microcode_patch) The first locates a matching microcode while the second loads that mircocode. These new functions can then be used to cache the found microcode blob w/o having to re-walk the CBFS. Booted baskingridge board to Linux and noted that all microcode revisions match on all the CPUs.

2012-09-05buildsystem: Make CPU microcode updating more configurableAlexandru Gagniuc
This patch aims to improve the microcode in CBFS handling that was brought by the last patches from Stefan and the Chromium team. Choices in Kconfig - 1) Generate microcode from tree (default) - 2) Include external microcode file - 3) Do not put microcode in CBFS The idea is to give the user full control over including non-free blobs in the final ROM image. MICROCODE_INCLUDE_PATH Kconfig variable is eliminated. Microcode is handled by a special class, cpu_microcode, as such: cpu_microcode-y += microcode_file.c MICROCODE_IN_CBFS should, in the future, be eliminated. Right now it is needed by intel microcode updating. Once all intel cpus are converted to cbfs updating, this variable can go away. These files are then compiled and assembled into a binary CBFS file. The advantage of doing it this way versus the current method is that 1) The rule is CPU-agnostic 2) Gives user more control over if and how to include microcode blobs 3) The rules for building the microcode binary are kept in src/cpu/Makefile.inc, and thus would not clobber the other makefiles, which are already overloaded and very difficult to navigate.
