Thanks for demonstarting that !

I'm really not confident about using proprietary tools from mainline u-boot
source tree.

Will the binman step quietly fail if tools/bins aren't available ?

--------------------------------------------------- C4

But i get the spirit !

Seems it should work as-is on allmost all boards except Odroid-C2 which has
only pre-signed binaries provided by HK.

The only work will be to replace acs_tool.py for pre-G12 SoCs.
