Arthur Heymans has uploaded this change for review. ( https://review.coreboot.org/25414
Change subject: src/sb/intel/common/spi.c: Adapt and link in romstage
......................................................................
src/sb/intel/common/spi.c: Adapt and link in romstage
Based on Nicola Corna's work.
This allows for CONFIG_CONSOLE_SPI_FLASH to be used, which writes the
console output to the SPI flash.
TESTED to still work in ramstage on x220 (correctly writes MRC CACHE),
the option CONFIG_CONSOLE_SPI_FLASH compiles for targets using the
common Intel SPI code (untested though).
