[U-Boot] [RFC PATCH v1 0/1] Migrate IMAGE_FORMAT_LEGACY to Kconfig

[Alex Kiernan]

On the face of it, this is a straightforward moveconfig, but because
of how CONFIG_FIT_SIGNATURE, CONFIG_IMAGE_FORMAT_LEGACY and
CONFIG_DISABLE_IMAGE_LEGACY interacted when you enabled
CONFIG_FIT_SIGNATURE, you got CONFIG_IMAGE_FORMAT_LEGACY disabled
immediately unless you had some way of explicitly enabling it
elsewhere.

Kconfig doesn't give us this - CONFIG_IMAGE_FORMAT_LEGACY starts off
enabled, CONFIG_FIT_SIGNATURE starts off disabled and if you enable
CONFIG_FIT_SIGNATURE then CONFIG_IMAGE_FORMAT_LEGACY stays enabled.

Is there some way to preserve the existing behaviour through Kconfig
that I've failed to figure out?
