2015-09-30amd/family14: Add k10temp thermal zone.Tobias Diedrich
The thermal sensor interface exposed in function 3 of the northbridge is a more convenient and faster way to access the processor-internal thermal sensor than using the SMBus/SB-TSI interface from the FCH, see the Family14 BKDG: "Tctl is a processor temperature control value used for processor thermal management. Tctl is accessible through SB-TSI and D18F3xA4[CurTmp]. Tctl is a temperature on its own scale aligned to the processors cooling requirements" Also on at least some of these boards the existing thermal zone is broken and always returns 40C (the default value if the SMBus read failed) because the SMBus muxing register (SmBus0Sel) is not set up correctly. Case in point: The fallback "smbus read failed" temperature is 40 C and the the logs taken from the board status repository for the Asrock E350M1 board all show: "ACPI: Thermal Zone [TZ00] (40 C)" e.g. http://review.coreboot.org/gitweb?p=board-status.git;a=blob;f=asrock/e350m1/4.0-5054-gf584218/2013-12-20T20:56:20Z/kernel_log.txt#l390 and http://review.coreboot.org/gitweb?p=board-status.git;a=blob;f=asrock/e350m1/4.0-7030-g6d7de4f/2014-10-16T15:34:19Z/kernel_console.txt#l404 and http://review.coreboot.org/gitweb?p=board-status.git;a=blob;f=asrock/e350m1/4.0-9989-gf2dfef0/2015-06-13T00:22:49Z/kernel_log.txt#l425 Example lm-sensors output with this patch on the pcengines APU1, on Linux 4.1.0-rc8+ (wiht both CONFIG_ACPI_THERMAL and CONFIG_SENSORS_K10TEMP enabled): acpitz-virtual-0 Adapter: Virtual device temp1: +54.0 C (crit = +100.0 C) k10temp-pci-00c3 Adapter: PCI adapter temp1: +54.0 C (high = +70.0 C) (crit = +100.0 C, hyst = +97.0 C) Change-Id: Id9c5b783ba424246816677099ec6651814e59f21 Signed-off-by: Tobias Diedrich <ranma+coreboot@tdiedrich.de> Reviewed-on: http://review.coreboot.org/10940 Tested-by: build bot (Jenkins) Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Patrick Georgi <pgeorgi@google.com>

2015-08-13amd: raminit sysinfo offset fixAaron Durbin
The sysinfo object within the k8 ram init is used to communicate progess/status from all the nodes in the system. However, the code was assuming where the sysinfo object lived in cache-as-ram. The layout of cache-as-ram is dynamic so one needs to do the lookup of the correct address at runtime. The way the amd code is compiled by #include'ing .c files makes the solution a little more complex in that some cache-as-ram support code needed to be refactored.

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.

2015-06-04devicetree: Rename unused parameter to passthruKyösti Mälkki
The actual use of the parameter max is to keep track of PCI bus number while recursively scanning PCI bridges or PCI-e rootports. Neither CPU, SMBus, LPC or other static buses are involved in this enumeration, but the way bridge operations were originally designed forced to pass this argument thru unrelated functions. Follow-up removes these once the function prototype gets fixed.

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.
