[RFC 0/4] FIT Support

[Jan Luebbe <jlu@pengutronix.de>]

Hi,

this is the current work-in-progress state of my FIT support patches.
The FIT loading code has basically been rewritten from scratch, as the
original U-Boot code uses libfdt and barebox's DT support works on an
in-memory tree.

These patches apply on v2015.03.0.
The two patches from Sascha are required for the basic RSA support.
The third patch adds FIT support.
The fourth patch contains some test data to use in the sandbox.

$ ./barebox -i key.dtb -i sign-configs.itb 
add file key.dtb()
add file sign-configs.itb()
