the following patch was just integrated into master: commit 6a503b6a0f08bf4236c4c37d75c67182a7af4b02 Author: David Hendricks dhendrix@chromium.org Date: Mon Dec 31 17:28:43 2012 -0800
make early serial console support more generic
This patch makes pre-RAM serial init more generic, particularly for platforms which do not necessarily need cache-as-RAM in order to use the serial console and do not have a standard 8250 serial port.
This adds a Kconfig variable to set romstage-* for very early serial console init. The current method assumes that cache-as-RAM should enable this, so to maintain compatibility selecting CACHE_AS_RAM will also select EARLY_SERIAL_CONSOLE.
The UART code structure needs some rework, but the use of ROMCC, romstage, and then ramstage makes things complex.
uart.h now includes all .h files for all uarts. All 2 of them. This is actually a simplifying change.
