[U-Boot] INTEL E3900 Apollo Lake I (APL-I) with U-Boot?

[Zoran Stojsavljevic]

Hello Bin,

list.

All Good. Please, take your time. If you do not mind, I would like to know
ASAP, do I have correct prediction/anticipation/vision how this whole thing
should work?

The one I originally described in my original/intro email to this email
thread? Namely: E3900/APL-I -> IFWI -> MBR -> U-Boot -> eLinux/YOCTO ?!

With the following/forwarding explanation (please, in original email)?

It is very important for me to know how the future U-Boot architecture will
look like for E3900/APL-I!

I would like to thank you in advance,
Zoran Stojsavljevic
