2017-09-20vboot: reset vbnv in cmos when cmos failure occursAaron Durbin
There's an occasional issue on machines which use CMOS for their vbnv storage. The machine that just powers up from complete G3 would have had their RTC rail not held up. The contents of vbnv in CMOS could pass the crc8 though the values could be bad. In order to fix this introduce two functions: 1. vbnv_init_cmos() 2. vbnv_cmos_failed() At the start of vboot the CMOS is queried for failure. If there is a failure indicated then the vbnv data is restored from flash backup or reset to known values when there is no flash backup.

2017-04-25lib: provide clearer devicetree semanticsAaron Durbin
The devicetree data structures have been available in more than just ramstage and romstage. In order to provide clearer and consistent semantics two new macros are provided: 1. DEVTREE_EARLY which is true when !ENV_RAMSTAGE 2. DEVTREE_CONST as a replacment for ROMSTAGE_CONST The ROMSTAGE_CONST attribute is used in the source code to mark the devicetree data structures as const in early stages even though it's not just romstage. Therefore, rename the attribute to DEVTREE_CONST as that's the actual usage. The only place where the usage was not devicetree related is console_loglevel, but the same name was used for consistency. Any stage that is not ramstage has the const C attribute applied when DEVTREE_CONST is used.

2015-08-14skylake: fix SMI GPI status handlingAaron Durbin
The current construction for processing SMI GPI events didn't allow for the mainboard to query the state of a particular GPI for the snapshotted SMI event. The skylake part can route GPIs from any (there are design limitations) GPIO group. Those status and enable registers are within the GPIO community so one needs to gather all the possibilities in order to query the state. The call chain did this: southbridge_smi_gpi( clear_alt_smi_status() -> reset_alt_smi_status() -> print_all_smi_status() -> return 0) As a replacement the following functions and types are introduced: struct gpi_status - represent gpi status. gpi_status_get() - per gpi query on struct gpi_status gpi_clear_get_smi_status() - clear and retrieve SMI GPI status mainboard_smi_gpi_handler() - mainboard handler using gpi_status Also remove gpio_enable_all_smi() as that construct was never used, but it also is quite heavy handed in that it would enable SMI generation for all GPIs.
