Original commit message:
MIPS: ath79: make bootconsole wait for both THRE and TEMT
This makes the ath79 bootconsole behave the same way as the generic 8250
bootconsole.
Also waiting for TEMT (transmit buffer is empty) instead of just THRE
(transmit buffer is not full) ensures that all characters have been
transmitted before the real serial driver starts reconfiguring the serial
controller (which would sometimes result in garbage being transmitted.)
This change does not cause a visible performance loss.
In addition, this seems to fix a hang observed in certain configurations on
many AR7xxx/AR9xxx SoCs during autoconfig of the real serial driver.
A more complete follow-up patch will disable 8250 autoconfig for ath79
altogether (the serial controller is detected as a 16550A, which is not
fully compatible with the ath79 serial, and the autoconfig may lead to
undefined behavior on ath79.)
Patch tested on v2016.1.x branch with Freifunk Magdeburg firmware on
Debian Jessie amd64 Xen host. See the same patch in our gluon fork here:
https://github.com/FreifunkMD/gluon/blob/fix-sysupgrade-xen/patches/openwrt/0058-x86-fix-platform_export_bootpart-for-Xen-virtual-disks.patch
Sysupgrade was tested successfully by manually making the change before
upgrading in the filesystem of the running node and upgrading to the
fixed FFMD experimental build in config mode via expert settings in
webgui.
Patch also submitted to OpenWRT trunk already.

The Hornet UB is sold at least in the varieties. Without case it is a Hornet UB, with case and without connected USB port it is called AP121. If the USB port is present this device is called AP121U.
We have a AP121U in our mesh http://meshviewer.chemnitz.freifunk.net/#!v:m;n:00c0ca6efffa
It is not supported by all browsers yet.
Also change load display always to display 2 decimal digits (as it is read
from the kernel with 2 decimal digits).
Fixes#606
Mobile browsers will often show or hide the address bar while scrolling.
This causes resize events which would often reset the signal graphs.
Fixes#662
Instead of starting gluon-respondd from a hotplug handler, add a proper
init script. The new init script has a restart_if_running argument which
is now used by the hotplug handler.
