Add SPI flash driver This driver is taken from u-boot and adapted to match coreboot. It still contains some hacks and is ICH specific at places.

Select this option if your chipset driver needs to store certain

SMM: Add option for SPI driver to be available in SMM - add Kconfig option for CONFIG_SPI_FLASH_SMM - compile subsystem and chip drivers for smm if enabled - change mdelay(1) to udelay(500) since mdelay is not defined in SMM and a 1ms delay is worth avoiding - make flash chip structure non-const so the probe function pointers can be relocated for use in TSEG - Make SMM PCI access possible in southbridge SPI code Change-Id: Icfcbbe8e4e56658769d46af0b5bf6c79a6432641 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: http://review.coreboot.org/1313 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

config SPI_FLASH_NO_FAST_READ
SPI: Fix and enable Fast Read support - Fix handling of 5-byte Fast Read command in the ICH SPI driver. This fix is ported from the U-boot driver. - Allow CONFIG_SPI_FLASH_NO_FAST_READ to be overridden by defining a name for the bool in Kconfig and removing the forced select in southbridge config - Fix use of CONFIG_SPI_FLASH_NO_FAST_READ in SPI drivers to use #if instead of #ifdef - Relocate flash functions in SMM so they are usable. This really only needs to happen for read function pointer since it uses a global function rather than a static one from the chip, but it is good to ensure the rest are set up correctly as well.
