2018-12-06soc/intel/apl: Warn if CBFS is outside the memory mapped areaNico Huber
As part of the memory mapped BIOS region is covered by SRAM, check that CBFS always fits the effectively mapped region of flash. This is usually taken care of by reserving the SRAM range in the FMAP (e.g. as BIOS_UNUSABLE), but can be missed.

2017-05-02soc/intel/apollolake: Clean up code by using common FAST_SPI moduleBarnali Sarkar
This patch currently contains the following - 1. Use SOC_INTEL_COMMON_BLOCK_FAST_SPI kconfig for common FAST_SPI code. 2. Perform FAST_SPI programming by calling APIs from common FAST_SPI library. 3. Use common FAST_SPI header file.

2016-12-15soc/intel/common: remove mrc cache assumptionsAaron Durbin
Update the mrc cache implementation to use region_file. Instead of relying on memory-mapped access and pointer arithmetic use the region_devices and region_file to obtain the latest data associated with the region. This removes the need for the nvm wrapper as the region_devices can be used directly. Thus, the library is more generic and can be extended to work on different boot mediums.

2016-03-08soc/intel/apollolake: Add support for memory-mapped boot mediaAndrey Petrov
On Apollo Lake SPI flash is memory mapped. The mapping is different to previous platforms. Only "BIOS" region is mapped in contrast to whole flash. Also, the 128 KiB right below 4 GiB are being decoded by readonly SRAM. Fail accesses to those regions, rather than returning false data.
