Intel® x86 Coreboot/FSP Development Process

+

+ The x86 development process for coreboot is broken into the following components: +

+ +

+ The development process has two main phases: +

+
    +
  1. Minimal coreboot; This phase is single threaded
    2. +
  2. Adding coreboot features
    3. +
+ +

Minimal Coreboot

+

+ The combined steps below describe how to bring up a minimal coreboot for a + system-on-a-chip (SoC) and a development board: +

+ + + + +
The initial coreboot steps are single threaded! + The initial minimal FSP development is also single threaded. + Progress can speed up by adding more developers after the minimal coreboot/FSP + implementation reaches the payload. +
+
    +
  1. Get the necessary tools: +
      +
    • Linux: Use your package manager to install m4 bison flex and the libcurses development + package. +
        +
      • Ubuntu or other Linux distribution that use apt, run: +
        sudo apt-get install m4 bison flex libncurses5-dev
+
        +
        • +
      +
      • +
    +
    2. +
  2. Build the cross tools for i386: +
      +
    • Linux: +
      make crossgcc-i386
      + To use multiple processors for the toolchain build (which takes a long time), use: +
      make crossgcc-i386 CPUS=N
      + where N is the number of cores to use for the build. +
      • +
    +
    3. +
  3. Get something to build: +
      +
    1. FSP 1.1 required files
      2. +
    2. SoC required files
      3. +
    3. Board required files
      4. +
    +
    4. +
  4. Get result to start booting
    5. +
  5. Early Debug
    6. +
+ + +
