2013-12-13cpu: Rename CPU_MICROCODE_IN_CBFS to SUPPORT_CPU_UCODE_IN_CBFSAlexandru Gagniuc
CPU_MICROCODE_IN_CBFS was designed to mean that loading microcode updates from a CBFS file is supported, however, the name implies that microcode is present in CBFS. This has recently caused confusion both with contributions from Google, as well as SAGE. Rename this option to SUPPORT_CPU_UCODE_IN_CBFS in order to make it clearer that what is meant is "hey, the code we have for this CPU supports loading microcode updates from CBFS", and prevent further confusion.

2013-09-21CBMEM: Always select CAR_MIGRATIONKyösti Mälkki
If romstage does not make cbmem_initialize() call, linker should optimize the code for CAR migration away. This simplifies design of CBMEM console by a considerable amount. As console buffer is now migrated within cbmem_initialize() call there is no longer need for cbmemc_reinit() call made at end of romstage.

Commit »haswell: 24MHz monotonic time implementation« (c46cc6f1) [1] added the Kconfig variable `MONOTONIC_TIMER_MSR` with a help text, but only used one space instead of the suggested two spaces for indentation.

2013-05-16haswell: enable cache-as-ram migrationAaron Durbin
The haswell code allows for vboot ramstage verification. However, that code path relies on accessing global cache-as-ram variables after cache-as-ram is torn down. In order to avoid that situation enable cache-as-ram migration. cbmemc_reinit() no longer needs to be called from romstage because it is invoked automatically by the cache-as-ram migration infrastructure.

2013-03-22haswell: use dynamic cbmemAaron Durbin
Convert the existing haswell code to support reloctable ramstage to use dynamic cbmem. This patch always selects DYNAMIC_CBMEM as this option is a hard requirement for relocatable ramstage. Aside from converting a few new API calls, a cbmem_top() implementation is added which is defined to be at the begining of the TSEG region. Also, use the dynamic cbmem library for allocating a stack in ram for romstage after CAR is torn down. Utilizing dynamic cbmem does mean that the cmem field in the gnvs chromeos acpi table is now 0. Also, the memconsole driver in the kernel won't be able to find the memconsole because the cbmem structure changed.

The RESET_ON_INVALID_RAMSTAGE_CACHE option indicates what to do when the ramstage cache is found to be invalid on a S3 wake. If selected the system will perform a system reset on S3 wake when the ramstage cache is invalid. Otherwise it will signal to load the ramstage from cbfs.

2013-03-21haswell: add multipurpose SMM memory regionAaron Durbin
The SMM region is available for multipurpose use before the SMM handler is relocated. Provide a configurable sized region in the TSEG for use before the SMM handler is relocated. This feature is implemented by making the reserved size a Kconfig option. Also make the IED region a Kconfig option as well. Lastly add some sanity checking on the Kconfig options.

2013-03-19haswell: Parallel AP bringupAaron Durbin
This patch parallelizes the AP startup for Haswell-based devices. It does not touch the generic secondary startup code. Instead it provides its own MP support matching up with the Haswell BWG. It seemed to be too much trouble to support the old startup way and this new way. Because of that parallel loading is the only thing supported. A couple of things to note: 1. Micrcode needs to be loaded twice. Once before MTRR and caching is enabled. And a second time after SMM relocation. 2. The sipi_vector is entirely self-contained. Once it is loaded and written back to RAM the APs do not access memory outside of the sipi_vector load location until a sync up in ramstage. 3. SMM relocation is kicked off by an IPI to self w/ SMI set as the destination mode. The following are timings from cbmem with dev mode disabled and recovery mode enabled to boot directly into the kernel. This was done on the baskingridge CRB with a 4-core 8-thread CPU and 2 DIMMs 1GiB each. The kernel has console enabled on the serial port. Entry 70 is the device initialization, and that is where the APs are brought up. With these two examples it looks to shave off ~200 ms of boot time.

This commit adds support for using the SMM modules for haswell-based boards. The SMI handling was also refactored to put the relocation handler and permanent SMM handler loading in the cpu directory. All tseg adjustment support is dropped by relying on the SMM module support to perform the necessary relocations.

2013-03-17x86 intel: Add Firmware Interface Table supportAaron Durbin
Haswell CPUs require a FIT table in the firmware. This commit adds rudimentary support for a FIT table. The number of entries in the table is based on a configuration option. The code only generates a type 0 entry. A follow-on tool will need to be developed to populate the FIT entries as well as checksumming the table. Verified image has a FIT pointer and table when option is selected.

2013-03-14haswell: Add initial support for Haswell platformsAaron Durbin
The Haswell parts use a PCH code named Lynx Point (Series 8). Therefore, the southbridge support is included as well. The basis for this code is the Sandybridge code. Management Engine, IRQ routing, and ACPI still requires more attention, but this is a good starting point. This code partially gets up through the romstage just before training memory on a Haswell reference board.
