* AUTHORS: Move src/drivers/[l*-v*] copyrights into AUTHORS fileMartin Roth2019-10-221-4/+0
| | | | | | | | | | | | | | | As discussed on the mailing list and voted upon, the coreboot project is going to move the majority of copyrights out of the headers and into an AUTHORS file. This will happen a bit at a time, as we'll be unifying license headers at the same time. Updated Authors file is in a separate commit.

* Fix code that would trip -Wtype-limitsJulius Werner2019-05-061-0/+3
| | | | | | | | | | | | | | | This patch fixes up all code that would throw a -Wtype-limits warning. This sometimes involves eliminating unnecessary checks, adding a few odd but harmless casts or just pragma'ing out the warning for a whole file -- I tried to find the path of least resistance. I think the overall benefit of the warning outweighs the occasional weirdness.

* vboot: Fix linking error with USE_OPTION_TABLE enabledPatrick Rudolph2018-06-281-12/+58
| | | | | | | | | | | | | | | | | | | | | | Fix a linking problem with VBOOT and USE_OPTION_TABLE enabled. Make use of cbfs_locate_file_in_region() and always search the cmos_layout.bin in the 'COREBOOT' region. With this change applied there's no need to include the vboot_locator in SMM any more, we can't break NVRAM with different CMOS layouts, and we keep VBOOT and non VBOOT behaviour the same. Only include cmos_layout.bin and cmos.default in RO region. Add notes explaining the decisions. Tested on Intel Sandybridge, builds and boots with vboot enabled.

* rtc: Force negative edge on SET after battery replacementMarshall Dawson2016-11-171-5/+8
| | | | | | | | | | | | | | | After the RTC coin cell has been replaced, the Update Cycle Inhibit bit must see at least one low transition to ensure the RTC counts. The reset value for this bit is undefined. Examples have been observed where batteries are installed on a manufacturing line, the bit's state comes up low, but the RTC does not count.

On reads, ensure the UIP bit is clear which guarantees a minimum of 244 microseconds exists before the update begins. Writes already avoid the problem by disabling the RTC count via the SET bit.
