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. Change-Id: I089e7af633c227baf3c06c685f005e9d0e4b38ce Signed-off-by: David Hendricks <dhendrix@chromium.org> Signed-off-by: Ronald G.
