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.

2019-08-04soc/intel/common/block/uart: Update the UART PCI device referenceAamir Bohra
This implementation revises the UART PCI device reference in common UART driver. The SOC functions have been aligned to provide the UART PCI device reference using pcidev_path_on_root. The uart_get_device() return type is changed, and files in which it gets used are updated.

2019-06-03soc/intel/{skl,cnl,icl}: Drop soc_uart_set_legacy_mode()Nico Huber
This is never called: The only calling path is guarded by both !DRIVERS_UART_8250MEM_32 and INTEL_LPSS_UART_FOR_CONSOLE but the latter selects the former. If somebody figures out how this is supposed to be used, we can easily revive the implementation.

2017-12-14soc/intel/cannonlake: Fix UART2 serial log broken issueSubrata Banik
Cannonlake rvp serial log has been regressed with commit I7eea910e065242689e87adac41281131674b39af(soc/intel/cannonlake: Clean up UART code) because of common UART code is unable to link all __weak function implementation from SoC uart.c due to existing macro #define __SIMPLE_DEVICE__. Hence UART2 PCI device resource programming is different than what it's been programmed before. This patch ensures UART2 PCI device resource enumeration is working and we are getting serial log as expected.
