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 trunk version of mac80211 doesn't need these dependencies anymore as
they are compiled into the kernel.
While this didn't cause any issues for Gluon as we always build the kernel
with all modules, this fix makes the patch work on a plain OpenWrt CC as
well.
ath9k expects to get revision id 2 for the QCA9531 ver. 2 rev. 0. This
fixes the very low TX power on some devices like the TP-LINK
TL-WR841ND v10.
As ath79_soc_rev is only used to get the revision number to ath9k on the
QCA9533, just set it to the expected value on the ver. 2.
This patch adds the kernel modules to for the very common Realtek RTL8150 and Realtek 8152 based USB-to-Ethernet converters.
After this patch the following packages can be added to targets (or site.mk):
kmod-usb-net-rtl8150
kmod-usb-net-rtl8152
The modules are already available in openwrt trunk, but not in Chaos Calmer. This patch is just a temporary backport.
The modules are needed for Futros with additional USB-Ethernet-Interface and VMs with dedicated USB-NIC
We can't use the same image for these two devices, so as a workaround,
remove ZR-600DHP from the name for now, so the autoupdater can work and
users aren't confused.
