Hi Fabio,

When CONFIG_IMX_HAB is selected the 'hab_status' command reports several error events, indicating that the BootROM failed to authenticate the SPL.
After inspecting the content of the memory location that corresponds to the DTB load address, the content did not match with the DTB binary, showing that some kind of memory corruption/overlap occurred.
Letting the CONFIG_SPL_FIT_IMAGE_TINY option to be selected causes the DTB to be properly placed into RAM and no more overlap occurs.
With this change, the 'hab_status' command returns no more error events, which indicates that the BootROM succeeded to authenticate the SPL.

Thanks for debugging!
I remember that enabling CONFIG_SPL_FIT_IMAGE_TINY resulted in aliases from the devicetree not being available anymore. This in turn caused the indexing of some devices to not be consistent between SPL, U-Boot proper and kernel. But I don't remember which exact problems were caused by this.
I tried this on top of my patchset [1] and at first glance I don't see any obvious problems, so I hope whatever I have in the back of my mind is not an issue anymore.
