2018-04-16drivers/pc80/tpm: Add some optional delay to tis_readresponse()Bill XIE
Certain TPMs (observed on Infineon SLB9635 installed on revolve 810 g1) seem to need some delay between tis_wait_valid() and tis_has_valid_data(), or tis_has_valid_data() may invalidly return 0, ending the loop immaturely with some bytes left unread, and fail to pass the check below, causing the current command not finalized by tis_command_ready(), and blocking any later tis_wait_ready(). This time the added delay is controlled by a Kconfig option TPM_RDRESP_NEED_DELAY.

On certain Winbond SuperIO devices, when a PS/2 mouse is not present on the auxiliary channel both channels will cease to function if the auxiliary channel is probed while the primary channel is active. Therefore, knowledge of mouse presence must be gathered by coreboot during early boot, and used to enable or disable the auxiliary PS/2 port before control is passed to the operating system. Add auxiliary channel PS/2 device presence detect, and update the Winbond W83667HG-A driver to flag the auxiliary channel as disabled if no device was detected.

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.

2015-11-03drivers/pc80: Rework normal / fallback selector codeTimothy Pearson
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.

With SPI TPMs there is no SERIRQ for interrupts, instead it is a PIRQ based interrupt. The TCG PC Client Platform TPM Profile Specification says it must be active low and shared.

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.
