Hello Patrick Rudolph, Lance Zhao,
I'd like you to do a code review. Please visit
https://review.coreboot.org/c/coreboot/+/33098
to review the following change.
Change subject: soc/intel: Replace UART_BASE() and friends with a Kconfig ......................................................................
soc/intel: Replace UART_BASE() and friends with a Kconfig
Re-add the Kconfig CONSOLE_UART_BASE_ADDRESS. It was lost by accident on APL at least. It is used outside of soc/intel/ scope, e.g. to con- figure SeaBIOS.
As we only ever configure a single UART for the coreboot console, we don't need different addresses for each possible UART. Which saves us a lot of code.
