[RFC PATCH v2 0/6] image: add a stage pre-load

[Philippe Reynes]

This serie adds a stage pre-load before launching an image.
This stage is used to read a header before the image and
this header contains the signature of the full image.
So u-boot may check the full image before using any
data of the image.

Changelog:
v2:
- move the code to image-pre-load
- add support of stage pre-load for spl
- add support of stage pre-load on spl_ram
