v1: This patchset updates the i.MX HAB layer in u-boot to fix a list of identified issues and then to add and extend existing functionality.
The first block of patches 0001-0006 deal with fixing existing code,
- Fixes indentation - Fixes the treatment of input parameters to hab_auth_image.
The second block of patches 0007-0013 are about tidying up the HAB code
- Remove reliance on hard-coding to specific offsets - IVT header drives locating CSF - Continue to support existing boards
Patches 0014 onwards extend out the HAB functionality.
- hab_rvt_check_target is a recommended check in the NXP documents to perform prior to hab_rvt_authenticate_image - hab_rvt_failsafe is a useful function to set the board into BootROM USB recovery mode.
