2019-11-03cpu/x86/tsc: Flip and rename TSC_CONSTANT_RATE to UNKNOWN_TSC_RATEKyösti Mälkki
The x86 timers are a bit of a mess. Cases where different stages use different counters and timestamps use different counters from udelays. The original intention was to only flip TSC_CONSTANT_RATE Kconfig to NOT_CONSTANT_TSC_RATE. The name would be incorrect though, those counters do run with a constant rate but we just lack tsc_freq_mhz() implementation for three platforms. Note that for boards with UNKNOWN_TSC_RATE=y, each stage will have a slow run of calibrate_tsc_with_pit(). This is easy enough to fix with followup implementation of tsc_freq_mhz() for the platforms. Implementations with LAPIC_MONOTONIC_TIMER typically will not have tsc_freq_mhz() implemented and default to UNKNOWN_TSC_RATE. However, as they don't use TSC for udelay() the slow calibrate_tsc_with_pit() is avoided. Because x86/tsc_delay.tsc was using two different guards and nb/via/vx900 claimed UDELAY_TSC, but pulled UDELAY_IO implementation, we also switch that romstage to use UDELAY_TSC.

This was eventually traced to concurrent access to the SP5100's SPI Flash controller by multiple APs during startup. Calls to the nvram read functions get_option and read_option call CBFS functions, which in turn make near-simultaneous requests to the SPI Flash controller, thus placing the SP5100 in an invalid state.

Per IRC and Gerrit discussion, the normal / fallback selector code is a rather weak spot in coreboot, and did not function correctly for certain use cases. Rework the selector to more clearly indicate proper operation, and also remove dead code. Also tentatively abandon use of RTC bit 385; a follow-up patch will remove said bit from all affected mainboards. The correct operation of the fallback code selector approximates that of a power line recloser, with a user option to attempt normal boot that can be cleared by firmware, but never set by firmware. Additionally, if cleared by user, the fallback path should always be used on the next reboot.

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.

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.

2015-04-10tpm: Add ramstage driver and interrupt configurationDuncan Laurie
This adds a ramstage driver for the TPM and allows the interrupt to be configured in devicetree.cb. The interrupt vector is set like other PNP devices, and the interrupt polarity is set with a register configuration variable. These values are written into locality 0 TPM_INT_VECTOR and TPM_INT_ENABLE and then all interrupts are disabled so they are not used in firmware but can be enabled by the OS. It also adds an ACPI device for the TPM which will configure the reported interrupt based on what has been written into the TPM during ramstage. The _STA method returns enabled if CONFIG_LPC_TPM is enabled, and the _CRS method will only report an interrupt if one has been set in the TPM itself. The TPM memory address is added by the driver and declared in the ACPI code. In order to access it in ACPI a Kconfig entry is added for the default TPM TIS 1.2 base address. Note that IO address 0x2e is required to be declared in ACPI for the kernel driver to probe correctly. BUG=chrome-os-partner:33385 BRANCH=samus,auron TEST=manual testing on samus: 1) Add TPM device in devicetree.cb with configured interrupt and ensure that it is functional in the OS. 2) Test with active high and active low, edge triggered and level triggered setups. 3) Ensure that with no device added to devicetree.cb that the TPM is still functional in polling mode.
