From e8e118dd324e32070a1550e3f8ff90dd6fad72f8 Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Fri, 12 Aug 2016 15:00:10 -0500 Subject: Kconfig: introduce writable boot device notion Indicate to the build system that a platform provides support for a writable boot device. The following will provide the necessary support: COMMON_CBFS_SPI_WRAPPER users soc/intel/apollolake soc/intel/baytrail soc/intel/braswell soc/intel/broadwell soc/intel/skylake The SPI_FLASH option is auto-selected if the platform provides write supoprt for the boot device and SPI flash is the boot device. Other platforms may provide similar support, but they do that in a device specific manner such as selecting SPI_FLASH explicitly. This provides clearance against build failures where chipsets don't provide SPI API implementations even though the platform may use a SPI flash to boot.
