2020-03-18soc: 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.

2020-03-17soc/amd/picasso: Move get_soc_config to common locationMarshall Dawson
Multiple files can eventually take advantage of the static function in i2c.c. Move get_soc_config() into a new common location for all to use.

2019-08-09soc/amd/picasso: Update i2c supportMarshall Dawson
Change the stoneyridge definitions into picasso. The named 0 and 1 buses are controlled by the PSP and not directly accessible by host firmware. I2C4 operates only in slave mode so is not added to to the bus clear-after-reset sequence. The I2C controller is fundamentally the same as on Stoney Ridge so the ability to clear a potentially jammed bus is still required. Program Picasso's new pad control registers in the MISC AcpiMmio space according to the recommended settings.

2019-07-02soc/amd/picasso: Create picasso as a copy of stoneyridgeMartin Roth
So that everyone can see what's being updated from stoney, we're starting with a direct copy of the stoney directory. There are arguments both for and against doing it this way, but I believe This the most transparent way. We've moved much of the duplicated stoney code into the soc/amd/common directory and will continue that work as it becomes obvious that we have unchanged code between the SOCs. Makefile.inc has been renamed as makefile.inc so that it won't build in jenkins until the directory is updated. Other than that change, this is an exact copy of the stoneyridge SOC directory which will be updated in the follow-on commits in the patch train.
