2020-03-18mainboard/google: Remove copyright noticesPatrick Georgi
They're listed in AUTHORS and often incorrect anyway, for example: - What's a "Copyright $year-present"? - Which incarnation of Google (Inc, LLC, ...) is the current copyright holder? - People sometimes have their editor auto-add themselves to files even though they only deleted stuff - Or they let the editor automatically update the copyright year, because why not? - Who is the copyright holder "The coreboot project Authors"? - Or "Generated Code"? Sidestep all these issues by simply not putting these notices in individual files, let's list all copyright holders in AUTHORS instead and use the git history to deal with the rest.

2017-12-20google/gru: Adjust to incorrect strapping resistors on KevinJulius Werner
It seems that RAM code 0 has been strapped with an incorrect resistor on Kevin. The resulting voltage divide still puts it well within the ADC value bucket reserved for that slot, but a little closer to the edge than necessary. While this doesn't seem to cause any immediate problems on its own, it still doesn't hurt to fix it (if only for the documentation value). On other boards (at least on my Scarlet) the strapping seems to be correct.

2017-12-07boardid: Minor clean up and standardizationJulius Werner
Merge the different coreboot table strapping ID structures into one because they're really just all the same, and I want to add more. Make the signature of the board_id() function return a uint32_t because that's also what goes in the coreboot table. Add a printk to the generic code handling strapping IDs in ramstage so that not every individual mainboard implementation needs its own print. (In turn, remove one such print from fsp1_1 code because it's in the way of my next patch.)

2016-05-09google/gru: Determine Board ID based on the input voltage of ADC1Vadim Bendebury
The Board ID on the Gru family of boards is determined by reading the voltage from a resistor divider, each hardware revision is supposed to have a unique resistor ratio, which allows to distinctly tell between different Board ID. While the long time approach to mapping resistor ratios (and voltages) into Board ID remains under discussion, we know for sure the values for Proto 1 and Proto 2. Let's just use them for now. Since Board ID can be queried multiple times during boot, ideally it should be read once and placed in the coreboot table to be available to all coreboot stages. For now we just cache it so that at least during the same stage the ADC has to run only once. BRANCH=None BUG=chrome-os-partner:51537 TEST=verified that the voltage reading on Proto 1 is as expected, and Board ID 0 is reported.
