Okay. I can confirm I can now boot the USB device to completion. I
was
also successfully able to upgrade the system using the "dnf -y update"
command and reboot successfully using the newer kernel. The key was
NOT to
create a new initramfs image after changing the UUIDs for the root
partition. As well, the cpuidle.off=1 kernel boot parameter was
required in
the extlinux.conf file.
I did NOT concatenate the u-boot.bin and u-boot.dtb files. I just
flashed
the u-boot.bin with the other files from Hardkernel that Dennis
specifies
below.
There are two problems I see right off the bat. First, as Dennis
mentions,
the USB3 ports do not work. Second, only 4 of the 8 cpus seem to be
working
based on a top command. Even so, the system actually seems pretty
responsive and usable.
What does lscpu show? I suspect being a big.little platform you'll
find that all the CPUs work but it might only run one cluster at a
time, or only power up the second cluster under load. I'm not sure
what the algorithms the cpu frequency drivers use for the exynos
platforms, I suspect it depends on other factors as well such as
thermal temp (the tmon util in kernel-tools might give you insight
there).
I will now attempt to get the system installed on the eMMC card. I
will
report on that progress later.

I also have a running F26, thanks to Dennis for his tips.

I've compared this system with a running F24 system and load the same
kernel modules via "modprobe".

The module "r8152" was manual loaded, but no Ethernet Adapter was found.
