v2:
- Fix compilation warnings and errors in SPL highlighted by 
  Breno Matheus Lima

- Add CC: Breno Matheus Lima <brenomatheus@gmail.com> to all patches

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.
