For a change I can help!
Been here, done a few things...

Hi -
I have a headless cubieboard 2 running a 3.4 kernel that came with the
board, but a Fedora rootfs already.
You are using:
https://fedorapeople.org/~lkundrak/a10-images/
stuff? It works well on my CB2. Well as well as can be expected with
the Allwinner 3.4 kernel, and part of the reason why there is now a
community effort to build an open uboot. Hans posted a note about this
back aways.
It's been pretty workable, but now I need to compile an OOT kernel
module, and that's a big mess with the magic 3.4 kernel. The defconfig
it was built with has gone 404, although a tarball of the sources
(with different defconfigs) exists.
So after reading the megathreads here about cubieboard 2 support
working, I went to look for a rawhide kernel package and give it a try.
I am using the F21 builds, rather than the rawhide. They are all there
together.
http://koji.fedoraproject.org/koji/tasks?state=all&view=tree&method=appliance&order=-id
with instructions at:
https://fedoraproject.org/wiki/Architectures/ARM/Rawhide/Installation
However after looking at Wikis that are out of date compared to the
mailing list, and an "Arm Koji" that only has 64-bit arm binaries in
the kernel package, I have no idea where to go to get the latest armhf
kernel package, U-Boot pieces etc.
Above is the 32 bit stuff. uboot is another issue, but I will give you
what Hans posted here and works for me:
On your development machine (mine is my F20 x86 notebook):
Cubieboard2 uboot:
yum install gcc-arm-linux-gnu gcc
git clone https://github.com/jwrdegoede/u-boot-sunxi.git
cd u-boot-sunxi
git checkout -B next origin/next
make -j4 CROSS_COMPILE=arm-linux-gnu- Cubieboard2_defconfig
make -j4 CROSS_COMPILE=arm-linux-gnu-
Everytime I make a new SDcard for a test F21 using:
fedora-arm-image-installer.sh
--image=Fedora-Xfce-armhfp-21-20140803-sda.raw.xz --target=Cubietruck
--media=/dev/sdb --norootpass
I run:
dd if=u-boot-sunxi-with-spl.bin of=/dev/sdb bs=1024 seek=8; sync
To overlay the Cubietruck uboot with the Cubieboard2 uboot. Works just
fine.
I think this respin concept is not a good idea, I see rotting one-off
"respins" including one from Feb for Cubieboard. But all I want is to
upgrade the 3.4 kernel to use a Fedora one with latest upstream
pieces. My fedora rootfs is already in good shape.
What steps should someone in this situation take to align themselves
with latest armv7 hf kernel and boot-related pieces that will work on
Cubieboard 2?
Note that F21 is locked into the uboot 3.16:
http://linux-sunxi.org/Linux_mainlining_effort
Perhaps rawhide will keep rolling in the latest uboot, but Hans has not
updated the uboot build I pointed out above for a while. He will have
to comment on what updates may be in the works before it is merged into
the Fedora uboot base.
Hope this helps.
