56518e7104 image: Support signing of images
Add support for signing images using a new signature node. The process
is handled by fdt_add_verification_data() which now takes parameters to
provide the keys and related information.

2f99807125 image: Use ENOENT instead of ENOMEDIUM for better compatibility
This error may not be defined on some platforms such as MacOS so host
compilation will fail. Use one of the more common errors instead.

c6ac13bdea sandbox: image: Adjust FIT image printing to work with sandbox
Use map_sysmem() to convert from address to pointer, so that sandbox can
print FIT information without crashing.

Use the new common code to load a kernel. The functionality should not

53f375fa81 image: Use fit_image_load() to load FDT
Use the new common code to load a flat device tree. Also fix up a few casts
so that this code works with sandbox. Other than that the functionality
should not change.

782cfbb259 image: Introduce fit_image_load() to load images from FITs
At present code to load an image from a FIT is duplicated in the three
places where it is needed (kernel, fdt, ramdisk).

The differences between these different code copies is fairly minor.
Create a new function in the fit code which can handle any of the
requirements of those cases.

87ebee39e9 image: Add CONFIG_FIT_SPL_PRINT to control FIT image printing in SPL
This code is very large, and in SPL it isn't always useful to print
out image information (in fact there might not even be a console
active). So disable this feature unless this option is set.

There are only two left. One is unnecessary and the other can be moved
to the header file.

d8b75360ee image: Rename hash printing to fit_image_print_verification_data()
This function will be used to print signatures as well as hashes, so rename
it. Also make it static since it is not used outside this file.

ab9efc665a image: Move hash checking into its own function
The existing function is long and most of the code is indented a long
way. Before adding yet more code, split this out into its own function.

b8da836650 image: Rename fit_image_check_hashes() to fit_image_verify()
This is the main entry point to the FIT image verification code. We will
be using it to handle image verification with signatures, so rename the
function.
