Hi,

I have got this patch some time ago but I am not still
100% sure about use case. Anyway Soren uses this mode
that's why let me send this patch and we can discuss
if this can be useful for someone else too.

The use case is to load U-Boot SPL to do init HW
and then load images via JTAG because RAM is initialized
and then run full u-boot.
There is an option to do HW initialization without
U-Boot SPL but there are some differences and it is just
better to directly use code which will run on the board
when everything is tested.

Thanks for your inputs,
Michal
