arm: imx: hab: Add IVT header definitions
The various i.MX BootROMs containing the High Assurance Boot (HAB) block
rely on a data structure called the Image Vector Table (IVT) to describe to
the BootROM where to locate various data-structures used by HAB during
authentication.
This patch adds a definition of the IVT header for use in later patches,
where we will break the current incorrect dependence on fixed offsets in
favour of an IVT described parsing of incoming binaries.

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.

arm: imx: hab: Fix authenticate_image result code
authenticate_image returns 1 for success and 0 for failure. That result
code is mapped directly to the result code for the command line function
hab_auth_img - which means when hab_auth_img succeeds it is returning
CMD_RET_FAILURE (1) instead of CMD_RET_SUCCESS (0).
This patch fixes this behaviour by making authenticate_image() return 0 for
success and 1 for failure. Both users of authenticate_image() as a result
have some minimal churn. The upshot is once done when hab_auth_img is
called from the command line we set $? in the standard way for scripting

arm: imx: hab: Make authenticate_image return int
Both usages of authenticate_image treat the result code as a simple binary.
The command line usage of authenticate_image directly returns the result
code of authenticate_image as a success/failure code.
Right now when calling hab_auth_img and test the result code in a shell a
passing hab_auth_img will appear to the shell as a fail.
The first step in fixing this behaviour is to fix-up the result code return
by authenticate_image() itself, subsequent patches fix the interpretation
of authenticate_image so that zero will return CMD_RET_SUCCESS and non-zero
will return CMD_RET_FAILURE.
The first step is fixing the return type in authenticate_image() so do that

Tegra186 currently restricts its DRAM usage to entries in the /memory node

tables, and thus prevents access to RAM that's not part of a valid bank.
Note: This patch is intended to prevent access to RAM regions which U-Boot
does not need to access, with the primary purpose of avoiding theoretical
speculative access to physical regions for which the HW will throw errors
(e.g. carve-outs that the CPU has no permission to access at a bus level,
bad ECC pages, etc.). In particular, this patch is not deliberately
related to the speculation-related security issues that were recently
announced. The apparent similarity is a coincidence.
