The uart node is enabled on all devices except one (GL-USB150 *).
Thus, let's not have a few hundred nodes to enable it, but do not
disable it in the first place.
Where the majority of devices is using it, also move the serial0
alias to the DTSI.
*) Since GL-USB150 even defines serial0 alias, the missing uart
is probably just a mistake. Anyway, disable it for now so this
patch stays cosmetic.
Apply this to 21.02 as well to remove an unnecessary backporting
pitfall.

Currently, we request LED labels in OpenWrt to follow the scheme
modelname:color:function
However, specifying the modelname at the beginning is actually
entirely useless for the devices we support in OpenWrt. On the
contrary, having this part actually introduces inconvenience in
several aspects:
- We need to ensure/check consistency with the DTS compatible
- We have various exceptions where not the model name is used,
but the vendor name (like tp-link), which is hard to track
and justify even for core-developers
- Having model-based components will not allow to share
identical LED definitions in DTSI files
- The inconsistency in what's used for the model part complicates
several scripts, e.g. board.d/01_leds or LED migrations from
ar71xx where this was even more messy
Apart from our needs, upstream has deprecated the label property
entirely and introduced new properties to specify color and
function properties separately. However, the implementation does
not appear to be ready and probably won't become ready and/or
match our requirements in the foreseeable future.
However, the limitation of generic LEDs to color and function
properties follows the same idea pointed out above. Generic LEDs
will get names like "green:status" or "red:indicator" then, and
if a "devicename" is prepended, it will be the one of an internal
device, like "phy1:amber:status".
With this patch, we move into the same direction, and just drop
the boardname from the LED labels. This allows to consolidate
a few definitions in DTSI files (will be much more on ramips),
and to drop a few migrations compared to ar71xx that just changed
the boardname. But mainly, it will liberate us from a completely
useless subject to take care of for device support review and
maintenance.
To also drop the boardname from existing configurations, a simple
migration routine is added unconditionally.
Although this seems unfamiliar at first look, a quick check in kernel
for the arm/arm64 dts files revealed that while 1033 lines have
labels with three parts *:*:*, still 284 actually use a two-part
labelling *:*, and thus is also acceptable and not even rare there.

The "/dts-v1/;" identifier is supposed to be present once at the
top of a device tree file after the includes have been processed.
In ath79, we therefore requested to have in the DTS files so far,
and omit it in the DTSI files. However, essentially the syntax of
the parent ath79.dtsi file already determines the DTS version, so
putting it into the DTS files is just a useless repetition.
Consequently, this patch puts the dts-v1 statement into the parent
ath79.dtsi, which is (indirectly) included by all DTS files. All
other occurences are removed.
Since the dts-v1 statement needs to be before any other definitions,
this also moves the includes to make sure the ath79.dtsi or its
descendants are always included first.

Buttons: 1x GPIO controlled
UART: 4 pin header near Mini PCIe card, starting count from white
triangle on PCB

baud: 115200, parity: none, flow control: none
MAC addresses
Calibration data does not contain valid MAC addresses.
The calculated MAC addresses are chosen in accordance with OEM firmware.
Because of:
a) constrained environment (SNMP) when connecting through Telnet
or SSH,
b) hard-coded kernel and rootfs sizes,
c) checksum verification of kerenel and rootfs images in bootloder,
creating factory image accepted by OEM web interface is difficult,
therefore, to install OpenWrt on this device UART connection is needed.
The teardown is simple, unscrew four screws to disassemble the casing,
plus two screws to separate mainboard from the casing.
Before flashing, be sure to have a copy of factory firmware, in case You
wish to revert to original firmware.
Installation
1. Prepare TFTP server with OpenWrt initramfs-kernel image.
2. Connect to LAN port.
3. Connect to UART port.
4. Power on the device and when prompted to stop autoboot, hit any key.
5. Alter U-Boot environment with following commands:
setenv failsafe_boot bootm 0x9f0a0000
saveenv
6. Adjust "ipaddr" and "serverip" addresses in U-Boot environment, use
'setenv' to do that, then run following commands:
tftpboot 0x81000000 <openwrt_initramfs-kernel_image_name>
bootm 0x81000000
7. Wait about 1 minute for OpenWrt to boot.
8. Transfer OpenWrt sysupgrade image to /tmp directory and flash it
with:
sysupgrade -n /tmp/<openwrt_sysupgrade_image_name>
9. After flashing, the access point will reboot to OpenWrt. Wait few
minutes, until the Power LED stops blinking, then it's ready for
configuration.
