I have to take this back, it seems that this build is appending:

" console=ttyS0,115200"

To the kernel cmdline, I've just double-checked and this is not upstream
behavior, is this being done by Fedora specific patches ?

This breaks kernel output and systemd status messages output on
tty0 / the hdmi output, resulting in a blackscreen until gdm
starts.

As discussed a while back, the proper way to do is set
stdout-path in the devicetree to the serial console, then the
kernel will automatically make it a second console, next to tty0
and output messages on both, and systemd will output messages
and spawn gettys on both too.

Upstream u-boot is already setting stdout-path for all sunxi
devices, so from a sunxi pov the appending of " console=ttyS0,115200"
is a regression. If this is done for some other boards, it would
be better to either patch those boards dts files to set stdout-path,
or u-boot to set stdout-path rather then appending " console=ttyS0,115200"
and breaking video output. If you can tell me which specific boards
need work here I can whip up a patch (for others to test).
