Terminology and Acronyms¶
Firmware Support Package. FSP is a binary image embedded in SBL to initialize main memory and chipset for Intel SoCs. It provides a standardized API that boot loaders call into in order to initialize the silicon. These APIs are required in order to boot an OS.
An FSP v2.0 compliant image consists of three subcomponents:
- FSP-T (Temporary Memory or Cache-As-RAM Initialization)
- FSP-M (Memory Initialization)
- FSP-S (Silicon Initialization)
- Integrated FirmWare Image. A complete flashable SPI image including all required firmware ingredients to boot on Intel platforms.
