This patch adds CC6 power save support to the AMD Family 15h support code. As CC6 is a complex power saving state that relies heavily on CPU, northbridge, and southbridge cooperation, this patch alters significant amounts of code throughout the tree simultaneously. Allowing the CPU to enter CC6 allows the second level of turbo boost to be reached, and also provides significant power savings when the system is idle due to the complete core shutdown.

2015-11-11arm/arm64: Generalize bootblock C entry pointJulius Werner
When we first added ARM support to coreboot, it was clear that the bootblock would need to do vastly different tasks than on x86, so we moved its main logic under arch/. Now that we have several more architectures, it turns out (as with so many things lately) that x86 is really the odd one out, and all the others are trying to do pretty much the same thing. This has already caused maintenance issues as the ARM32 bootblock developed and less-mature architectures were left behind with old cruft. This patch tries to address that problem by centralizing that logic under lib/ for use by all architectures/SoCs that don't explicitly opt-out (with the slightly adapted existing BOOTBLOCK_CUSTOM option). This works great out of the box for ARM32 and ARM64. It could probably be easily applied to MIPS and RISCV as well, but I don't have any of those boards to test so I'll mark them as BOOTBLOCK_CUSTOM for now and leave that for later cleanup.

2015-10-14x86: add standalone verstage supportAaron Durbin
To support x86 verstage one needs a working buffer for vboot. That buffer resides in the cache-as-ram region which persists across verstage and romstage. The current assumption is that verstage brings cache-as-ram up and romstage tears cache-as-ram down. The timestamp, cbmem console, and the vboot work buffer are persistent through in both romstage and verstage. The vboot work buffer as well as the cbmem console are permanently destroyed once cache-as-ram is torn down. The timestamp region is migrated. When verstage is enabled the assumption is that _start is the romstage entry point. It's currently expected that the chipset provides the entry point to romstage when verstage is employed. Also, the car_var_*() APIs use direct access when in verstage since its expected verstage does not tear down cache-as-ram. Lastly, supporting files were added to verstage-y such that an x86 verstage will build and link. BUG=chrome-os-partner:44827 BRANCH=None TEST=Built and booted glados using separate verstage.

The code flow doesn't fall through to walkcbfs, as it does in the rest of bootblock.S. Instead, walkcbfs is called (albeit via a jmp). The linker cannot know this when walkcbfs.S is included directly. When we use a CAR bootblock, we lose several hundred bytes because walkcbfs is not garbage-collected, yet it isn't used. This problem is solved by assembling walkcbfs.S separately, and linking it.

2015-10-07x86/bootblock: Use LDFLAGS_bootblock to enable garbage collectionAlexandru Gagniuc
The x86 bootblock linking is a mess. The bootblock is treated in a very special manner, and never received the update to link-time garbage collection. On newer x86 platforms, the boot media is no longer memory-mapped. That means we need to do a lot more setup in the bootblock. ROMCC is unsuitable for this task, and walkcbfs only works on memory-mapped CBFS. We need to revise the x86 bootflow for this new case. The approach this patch series takes is to perform CAR setup in the bootblock, and load the following stage (either romstage or verstage) from the boot media. This approach is not new, but has been done on our ARM ports for years. Since we will be adding .c files to the bootblock, it is prudent to use link-time garbage collection. This is also consistent to how we do things on other architectures. Unification FTW!

2015-09-30x86: prepare cache-as-ram to allow multiple stagesAaron Durbin
In order to do a verification of romstage on x86 one needs to run verstage which verifies romstage (and the memory init code). However, x86 doesn't have SRAM like every other modern SoC so managing the cache-as-ram region is especially critical. First move all of the "shared" objects to the beginning of the .car.data section. This change then ensures that each stage using car.ld to link has the same consistent view of the addresses of these fixed-sized objects in cache-as-ram. The CAR_GLOBALs can be unique per stage. However, these variables are expected to have a value of zero at the start of each stage. In order to allow a stage to provide those semantics outside of the initial cache-as-arm setup routine add _car_global_start and _car_global_end symbols. Those symbols can be used to clear the CAR_GLOBALs for that stage. Note that the timestamp region can't be moved out similarly to the pre-ram cbmem console because the object storage of the timestamp cache is used *after* cache-as-ram is torn down to indicate if the cache should be used or not. Therefore, that timestamp needs to migrated to ram. A logic change in src/lib/timestamp.c could alleviate this requirement, but that task wasn't tackled in this patch.

2015-09-09x86: don't create MAINBOARDDIR/romstage.inc for !ROMCC boardsAaron Durbin
Previously, the x86 romstage build process was unconditionally creating a romstage.inc and adding it to crt0s. This step is inherently not necessary in the !ROMCC case becaue the romstage.inc was created by the compiler outputting assembler. That means MAINBOARDDIR/romstage.c is truly a C environment that requires some sort of assembler stub to call into (cache_as_ram.inc from the chipset dirs). Therefore, remove this processing. The result is that MAINBOARDDIR/romstage.c can use the normal build steps in creating an object and linking. The layout of romstage.elf will change but that's only from a symbol perspective.

Add the timestamp tick frequency within the timestamp table so the cbmem utility doesn't try to figure it out on its own. Those paths still exist for x86 systems which don't provide tsc_freq_mhz(). All other non-x86 systems use the monotonic timer which has a 1us granularity or 1MHz. One of the main reasons is that Linux is reporting /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq as the true turbo frequency on turbo enables machines. This change also fixes the p-state values honored in cpufreq for turbo machines in that turbo p-pstates were reported as 100MHz greater than nominal.

2015-06-09cbmem: Unify CBMEM init tasks with CBMEM_INIT_HOOK() APIKyösti Mälkki
Squashed and adjusted two changes from chromium.git. Covers CBMEM init for ROMTAGE and RAMSTAGE. cbmem: Unify random on-CBMEM-init tasks under common CBMEM_INIT_HOOK() API There are several use cases for performing a certain task when CBMEM is first set up (usually to migrate some data into it that was previously kept in BSS/SRAM/hammerspace), and unfortunately we handle each of them differently: timestamp migration is called explicitly from cbmem_initialize(), certain x86-chipset-specific tasks use the CAR_MIGRATION() macro to register a hook, and the CBMEM console is migrated through a direct call from romstage (on non-x86 and SandyBridge boards). This patch decouples the CAR_MIGRATION() hook mechanism from cache-as-RAM and rechristens it to CBMEM_INIT_HOOK(), which is a clearer description of what it really does. All of the above use cases are ported to this new, consistent model, allowing us to have one less line of boilerplate in non-CAR romstages. BRANCH=None BUG=None TEST=Built and booted on Nyan_Blaze and Falco with and without CONFIG_CBMEM_CONSOLE. Confirmed that 'cbmem -c' shows the full log after boot (and the resume log after S3 resume on Falco). Compiled for Parrot, Stout and Lumpy.

Oops. This patch fixes the issue by extending the CBMEM_INIT_HOOK() mechanism to the cbmem_initialize() call in ramstage. The macro is split into explicit ROMSTAGE_/RAMSTAGE_ versions to make the behavior as clear as possible and prevent surprises (although just using a single macro and relying on the Makefiles to link an object into all appropriate stages would also work). This allows us to get rid of the explicit cbmemc_reinit() in ramstage (which I somehow accounted for in the last patch without realizing that timestamps work exactly the same way...), and replace the older and less flexible cbmem_arch_init() mechanism. Also added a size assertion for the pre-RAM CBMEM console to memlayout that could prevent a very unlikely buffer overflow I just noticed. BRANCH=None BUG=None TEST=Booted on Pinky and Falco, confirmed that ramstage timestamps once again show up. Compile-tested for Rambi and Samus.

2015-06-05lib: Unify log2() and related functionsJulius Werner
This patch adds a few bit counting functions that are commonly needed for certain register calculations. We previously had a log2() implementation already, but it was awkwardly split between some C code that's only available in ramstage and an optimized x86-specific implementation in pre-RAM that prevented other archs from pulling it into earlier stages. Using __builtin_clz() as the baseline allows GCC to inline optimized assembly for most archs (including CLZ on ARM/ARM64 and BSR on x86), and to perform constant-folding if possible. What was previously named log2f on pre-RAM x86 is now ffs, since that's the standard name for that operation and I honestly don't have the slightest idea how it could've ever ended up being called log2f (which in POSIX is 'binary(2) LOGarithm with Float result, whereas the Find First Set operation has no direct correlation to logarithms that I know of). Make ffs result 0-based instead of the POSIX standard's 1-based since that is consistent with clz, log2 and the former log2f, and generally closer to what you want for most applications (a value that can directly be used as a shift to reach the found bit). Call it __ffs() instead of ffs() to avoid problems when importing code, since that's what Linux uses for the 0-based operation. CQ-DEPEND=CL:273023 BRANCH=None BUG=None TEST=Built on Big, Falco, Jerry, Oak and Urara. Compared old and new log2() and __ffs() results on Falco for a bunch of test values.

2015-06-02cbfs: new API and better program loadingAaron Durbin
A new CBFS API is introduced to allow making CBFS access easier for providing multiple CBFS sources. That is achieved by decoupling the cbfs source from a CBFS file. A CBFS source is described by a descriptor. It contains the necessary properties for walking a CBFS to locate a file. The CBFS file is then decoupled from the CBFS descriptor in that it's no longer needed to access the contents of the file. All of this is accomplished using the regions infrastructure by repsenting CBFS sources and files as region_devices. Because region_devices can be chained together forming subregions this allows one to decouple a CBFS source from a file. This also allows one to provide CBFS files that came from other sources for payload and/or stage loading. The program loading takes advantage of those very properties by allowing multiple sources for locating a program. Because of this we can reduce the overhead of loading programs because it's all done in the common code paths. Only locating the program is per source.

Using --whole-archive, the linker doesn't optimize out object files just because their symbols were already provided by weak versions. However it shouldn't be used for libgcc, because that one has some unexpected side-effects.
