Coreboot is migrating platforms from a romcc bootblock to C_ENVIRONMENT_BOOTBLOCK in which Cache-as-Ram is set up in the bootblock. When migrating Braswell, chromebooks featuring this SOC did not boot anymore while other boards did. Google uses a different FSP binary than the one present in the Intel Github FSP repository. Previously the romcc bootblock set up caching of the ROM, located microcodes and performed the update before calling FSP TempRaminit.
