The HAB FlexSPI boot use-case is currently broken, albeit the BootROM
does the same steps as for MMC/SD. To fix this we need a 2nd CSF slot,
since the HAB ROM code expect the IVT and payload data to be signed by
the code signing tool (CST) and the MMC/SD IVT does differ slightly from
the FlexSPI IVT.
Please check the upcoming documentation patch for a in detail image
layout overview.
