Develop a generic boot console description

Registered by Deepak Saxena on 2012-11-13

As part of the single zImage work, we need a method to determine the boot console parameters for use by low-level debug (DEBUG_LL) and uncompress message code. The main proposal for this has been to create a DT node that would contain the address of the character write and status registers for a UART along with expected flag value for when the UART is ready for a character. This will only work in the case of a standard style UART that requires no tweaking but it should cover the majority of use cases.

Whiteboard

[arnd-arndb 2013-02-25] The new approach is to use the platform specifi debug_ll code, and include that into the uncompressor as well, which makes the more complex generic solution obsolete.
[jakub-pavelek 2023-02-25] Making deferred
[jakub-pavelek 2013-04-08] Not deferred, but not needed anymore. Making as Implemented to get rid of it.
