On many x86 platforms the boot device is SPI which is memory mapped. However, in order to write to the boot device one needs to use the SPI api. Therefore, provide a common implementation of boot_device_rw() which has no mmap() functionality. It only reads, writes, and erases. This will be used in the existing infrastructure but in a SPI agnostic way. Two options are added: 1. BOOT_DEVICE_SPI_FLASH_RW_NOMMAP 2. BOOT_DEVICE_SPI_FLASH_RW_NOMMAP_EARLY The former is auto-selected when COMMON_CBFS_SPI_WRAPPER is not selected. The latter can be used to include the implementation in the early stages such as bootblock, verstage, and romstage.
