The hab_rvt_failsafe() callback according to the HABv4 documentation:
"This function provides a safe path when image authentication has failed
and all possible boot paths have been exhausted. It is intended for use by
post-ROM boot stage components, via the ROM Vector Table."
Once invoked the part will drop down to its BootROM USB recovery mode.
Should it be the case that the part is in secure boot mode - only an
appropriately signed binary will be accepted by the ROM and subsequently
executed.

The BootROM will not successfully process a HAB image passed by u-boot
unless the board has been set into locked mode. Some of the existing usages
of authenticate_image() expect and rely on unlocked boards doing the
following
1. Not calling into the BootROM authenticate_image() callback
2. Returning a pass status for authenticate_image() calls anyway
A previous patch removed the necessity to call into imx_hab_is_enabled()
twice. This patch ensures the reliance on authenticate_image() returning
zero is maintained.

u-boot command "hab_auth_img" tells a user that it takes
- addr - image hex address
- offset - hex offset of IVT in the image
but in fact the callback hab_auth_img makes to authenticate_image treats
the second 'offset' parameter as an image length.
Furthermore existing code requires the IVT header to be appended to the end
of the image which is not actually a requirement of HABv4.
This patch fixes this situation by
1: Adding a new parameter to hab_auth_img
- addr : image hex address
- length : total length of the image
- offset : offset of IVT from addr
2: Updates the existing call into authenticate_image() in
arch/arm/mach-imx/spl.c:jump_to_image_no_args() to pass
addr, length and IVT offset respectively.
This allows then hab_auth_img to actually operate the way it was specified
in the help text and should still allow existing code to work.
It has the added advantage that the IVT header doesn't have to be appended
to an image given to HAB - it can be prepended for example.
Note prepending the IVT is what u-boot will do when making an IVT for the
BootROM. It should be possible for u-boot properly authenticate images
made by mkimage via HAB.
This patch is the first step in making that happen subsequent patches will
focus on removing hard-coded offsets to the IVT, which again is not
mandated to live at the end of a .imx image.

The first step in fixing this behaviour is to fix-up the result code return

At the same time modern distribution like Fedora require U-Boot to
select a proper devicetree which depends on the SoC variant and the
baseboard.
Thus, export the SoC variant and the actual board to the environment
following the conventions of other i.MX6 devices (e.g. the NXP boards)
such that the environment can select a devicetree file to load.
For now, we only know for sure that the cm-fx6 module and the SB-fx6m
