2016-08-31skylake: Add initial FSP2.0 supportRizwan Qureshi
Add Initial pieces of code to support fsp2.0 in skylake keeping the fsp1.1 flow intact. The soc/romstage.h and soc/ramstage.h have a reference to fsp driver includes, so split these header files for each version of FSP driver. Add the below files, car_stage.S: Add romstage entry point (car_stage_entry). This calls into romstage_fsp20.c and aslo handles the car teardown. romstage_fsp20.c: Call fsp_memory_init() and also has the callback for filling memory init parameters. Also add monotonic_timer.c to verstage. With this patchset and relevant change in kunimitsu mainboard, we are able to boot to romstage.

2016-08-31i945: Enable changing VRAM sizeArthur Heymans
On i945 the vram size is the default 8mb. It is also possible to set it 1mb or 0mb hardcoding the GGC register in early_init.c The intel documentation on i945, "Mobile Intel® 945 Express Chipset Family datasheet june 2008" only documents those three options. They are set using 3 bits. The documententation also makes mention of 4mb, 16mb, 32mb, 48mb, 64mb but not how to set it. The other non documented (straight forward) bit combinations allow to change the VRAM size to those other states. What this patch does is: - add those undocumented registers with their respective vram size to the i945 NB code; - make this a cmos option on targets that have this northbridge. TEST: build, flash to target, set cmos as desired and boot linux. On Debian it can be found using "dmesg | grep stolen". NOTE: dmesg message about reserved vram are quite different depending on linux version Change-Id: Ia71367ae3efb51bd64affd728407b8386e74594f Signed-off-by: Arthur Heymans <arthur@aheymans.xyz> Reviewed-on: https://review.coreboot.org/14819 Tested-by: build bot (Jenkins) Reviewed-by: Martin Roth <martinroth@google.com>

2016-08-30fsp_broadwell_de: Refactor code for SPI debug messagesWerner Zeh
Currently boards based on fsp_broadwell_de fail to compile if the config switch CONFIG_DEBUG_SPI_FLASH is selected. The error is caused by the usage of const for the address pointer in the functions writeb_, writew_ and writel_. The reason why it stayed hidden for so long is the fact that the switch is used with the preprocessor and nobody really selects it until there is a bug one want to find in this area. This patch fixes the parameter type definition which solves the error. In addition the config switch is not used on preprocessor level anymore but instead on compiler level. This ensures that at least the code syntax is checked on build time even if the config option is not selected. Also prefix the messages with "SPI:" to make them more meaningful in a full log.

2016-08-27cbmem: Always maintain backing store struct in a global on non-x86Julius Werner
The current CBMEM code contains an optimization that maintains the structure with information about the CBMEM backing store in a global variable, so that we don't have to recover it from cbmem_top() again every single time we access CBMEM. However, due to the problems with using globals in x86 romstage, this optimization has only been enabled in ramstage. However, all non-x86 platforms are SRAM-based (at least for now) and can use globals perfectly fine in earlier stages. Therefore, this patch extends the optimization on those platforms to all stages. This also allows us to remove the requirement that cbmem_top() needs to return NULL before its backing store has been initialized from those boards, since the CBMEM code can now keep track of whether it has been initialized by itself.

2016-08-27cbfs: Add "struct" file type and associated helpersJulius Werner
This patch adds functionality to compile a C data structure into a raw binary file, add it to CBFS and allow coreboot to load it at runtime. This is useful in all cases where we need to be able to have several larger data sets available in an image, but will only require a small subset of them at boot (a classic example would be DRAM parameters) or only require it in certain boot modes. This allows us to load less data from flash and increase boot speed compared to solutions that compile all data sets into a stage. Each structure has to be defined in a separate .c file which contains no functions and only a single global variable. The data type must be serialization safe (composed of only fixed-width types, paying attention to padding). It must be added to CBFS in a Makefile with the 'struct' file processor.

2016-08-27lenovo/x200,t400: enable C4 cpu low power stateArthur Heymans
This enables the C4 low power state on the lenovo x200 and t400. It's inspired by the thread on the mailinglist: "[coreboot] Lenovo X200 running Coreboot drains 3-4W more power than with Vendor BIOS". What this does, is to enable a C3 state using MWAIT(C3) request and set the southbridge config c4onc3_enable to automatically upgrade C3 to the lower power C4 state. The latency (0x37) is the same value used by the vendor bios. With C4 enabled the idle power consumption is about ~2-3W lower. TEST= build and install on target. Use powertop top to measure power usage.

2016-08-26sb/amd/sb700: Add option to increase SPI speed to 33MHzTimothy Pearson
Some SB700-based systems and ROMs support high speed (33MHz) SPI access instead of the power-on default 16.5MHz. Add an option to enable high speed SPI access in the bootblock, and set the default value to Disabled. This greatly decreases boot time on SB700-based systems, especiall when a large payload is in use. On a KGPE-D16 with a Petitboot (Linux + initramfs) payload, the command prompt was accessible within 20 seconds of power on, which incidentally is faster than the proprietary BIOS on the same machine could even reach the GRUB bootloader.

2016-08-25vboot: consolidate google_chromeec_early_init() callsAaron Durbin
On x86 platforms, google_chromeec_early_init() is used to put the EC into RO mode when there's a recovery request. This is to avoid training memory multiple times when the recovery request is through an EC host event while the EC is running RW code. Under that condition the EC will be reset (along with the rest of the system) when the kernel verification happens. This leads to an execessively long recovery path because of the double reboot performing full memory training each time. By putting this logic into the verstage program this reduces the bootblock size on the skylake boards. Additionally, this provides the the correct logic for all future boards since it's not tied to FSP nor the mainboard itself. Lastly, this double memory training protection works only for platforms which verify starting from bootblock. The platforms which don't start verifying until after romstage need to have their own calls (such as haswell and baytrail).

2016-08-24drivers/spi: remove unconditional RW boot device initializationAaron Durbin
The SPI drivers for the various chipsets are not consistent in their handling of when they are accessible. Coupled with the unknown ordering of boot_device_init() being called this can lead to unexpected behavior (probing failures or hangs). Instead move the act of initializing the SPI flash boot device to when the various infrastructure requires its usage when it calls boot_device_rw(). Those platforms utilizing the RW boot device would need to ensure their SPI drivers are functional and ready when the call happens. This further removes any other systems failing to boot as reported in https://ticket.coreboot.org/issues/67.
