I have use the manual process.

1- I have write the minimal image on the sdcard with :

    $> xzcat Fedora-Minimal-armhfp-21-5-sda.raw.xz | sudo dd of=$MEDIA; sync

2- I have write the uboot.imx file from the /usr/share/uboot/wandboard_quad/ of the just writed sdcard with :
    $> sudo dd if=path/u-boot.imx of=/dev/mymdia bs=1k seek=1 conv=fsync; sync

I think I have tried 2 times, but if other people have tested with succeed, I whould have to test again.

But it's probably me who made a mistake.

Sorry :)


PS: If it can change something, I have a wandboard quad "rev C1".

We already ship an equivalent patch of the one you reference above, a
number of people regularly use and have tested the wandboard quad on
Fedora 21 and 22 etc. You don't mention whether you use the automated
scripted install using fedora-arm-installer or a manual process.
