To quote the author: U-Boot provides a verified-boot feature based around FIT, but there is no standard way of implementing it for a board. At present the various required pieces must be built up separately, to produce a working implementation. In particular, there is no built-in support for selecting A/B boot or recovery mode. This series introduces VPL, a verified program loader phase for U-Boot. Its purpose is to run the verified-boot process and decide which SPL binary should be run. It is critical that this decision happens before SPL runs, since SPL sets up SDRAM and we need to be able to update the SDRAM-init code in the field. Adding VPL into the boot flow provides a standard place to implement verified boot. This series includes the phase itself, some useful Kconfig options and a sandbox_vpl build for sandbox. No verfied-boot support is provided in this series. Most of the patches in this series are fixes and improvements to docs and various Kconfig conditions for SPL. |
