Abstract
SPI firmware updates can be performed at runtime. A secure SPI flash access domain can be created during pre-boot and used at runtime to deliver and write a SPI firmware update to SPI flash. The secure SPI flash access domain can ensure that only a trusted component running on a trusted CPU core can access a SPI memory layout used to deploy the SPI firmware update to the SPI flash. Once the SPI firmware update is written to the SPI flash, a reboot can be triggered so that the updated SPI firmware is loaded to perform the boot process.
