[U-Boot] [PATCH v2 0/4] Allow disabling non-FIT image loading from SPL

[Andrew F. Davis]

Hello all,

To address a needed feature brought up by Andreas[0], we need a way to
disable SPL from loading non-FIT images.

The function spl_parse_image_header is common to all SPL loading paths
(common/spl/spl_(nand|net|nor|etc..)) so we add the check here, much
like the existing CONFIG_SPL_ABORT_ON_RAW_IMAGE.

My original attempt was to add CONFIG_SPL_PANIC_ON_MKIMAGE, but then if other
formats are added, flaws in restricting image types may be introduced, so we
would like a single option to restrict all non-FIT types vs disabling types
individually.

Thanks,
Andrew

Changes from v1:
 - Changed to abort on non-FIT so other boot methods can be attempted.
 - Made this a default if SPL_FIT_SIGNATURE is selected.
