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.

2018-05-08soc/intel/skylake: Support PCH UART 0 and 1 for consoleDuncan Laurie
The current PCH UART support for console is limited to UART2. This change adds support for specifying UART0 or UART1 to be used instead by changing CONFIG_UART_FOR_CONSOLE in the board level Kconfig. The default is still 2. This is tested with a board that uses UART0 for debug output.

1. Add a new variable to GNVS to store information during S3 suspend whether UART debug port controller is enabled. 2. On resume, read stored GNVS variable to decide if UART debug port controller needs to be initialized. 3. Provide helpers functions required by intel/common UART driver for enabling controller on S3 resume. BUG=b:64030366 TEST=Verified behavior with different combinations: 1. Serial console enabled in coreboot: No change in behavior. 2. Serial console enabled only in kernel: coreboot initializes debug controller on S3 resume. 3. Serial console not enabled in coreboot and kernel: coreboot skips initialization of debug controller on S3 resume.
