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.

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.

The bootloader only writes the first 2MB of the image to the NOR flash
when installing the NAND factory image. The bootloader is capable of
booting larger kernels as it boots from the memory mapped SPI flash.
Disable the NAND factory image. The NAND can be bootstrapped by writing
the NAND initramfs image using the NOR upgrade method in the bootloader
web-recovery and sysupgrading from there. The NOR variant is not
affected.
Also refactor the partition definitions in the DTS to make them less
annoying to read.

In ath79, for several SoCs the console bootargs are defined to the
very same value in every device's DTS. Consolidate these definitions
in the SoC dtsi files and drop further redundant definitions elsewhere.
The only device without any bootargs set has been OpenMesh OM5P-AC V2.
This will now inherit the setting from qca955x.dtsi
Note that while this tidies up master a lot, it might develop into a
frequent pitfall for backports.

A new shift mode was introduced since ar934x which has a way better
performance than current bitbang driver and can handle higher spi
clock properly. This commit adds a new driver to make use of this
new feature.
This new driver has chipselect properly configured and we don't need
cs-gpios hack in dts anymore. Remove them.

The "/dts-v1/;" identifier is supposed to be put once at the beginning
of a device tree file. Thus, it makes no sense to provide it a second
time in to-be-included DTSI files.
This removes the identifier from all DTSI files in /target/linux.
Most of the DTS files in OpenWrt do contain the "/dts-v1/;". It is
missing for most of the following targets, though:
mvebu, ipq806x, mpc85xx, ipq40xx
This does not touch ipq806x for now, as the bump to 4.19 is close.

The GL.iNet GL-AR750S has been supported by the ar71xx and ath79
platforms with access to its 16 MB NOR flash, but not its 128 MB
SPI NAND flash.
This commit provides support for the NAND through the upstream
SPI-NAND framework.
At this time, the OEM U-Boot appears to only support loading the
kernel from NOR. This configuration is preserved as this time,
with the glinet,gl-ar750s-nand name reserved for a potential,
future, NAND-only boot.
The family of GL-AR750S devices on the ath79 platform now includes:
* glinet,gl-ar750m-nor-nand "nand" target
* glinet,gl-ar750m-nor "nand" target (NAND-aware)
NB: This commit increases the kernel size from 2 MB to 4 MB
"Force-less" sysupgrade is presently supported from the current
versions of following NOR-based firmwre images to the version of
glinet,gl-ar750s-nor firmware produced by this commit:
* glinet,gl-ar750s -- OpenWrt 19.07 ar71xx
* glinet,gl-ar750s -- OpenWrt 19.07 ath79
Users who have sucessfully upgraded to glinet,gl-ar750m-nor may then
flash glinet,gl-ar750m-nor-nand with sysupgrade to transtion to the
NAND-based variant.
Other upgrades to these images, including directly to the NAND-based
glinet,gl-ar750s-nor-nand firmware, can be accomplished through U-Boot.
NB: See "ath79: restrict GL-AR750S kernel build-size to 2 MB" which
enables flashing of NAND factory.img with the current GL-iNet U-Boot,
"U-Boot 1.1.4-gcf378d80-dirty (Aug 16 2018 - 07:51:15)"
The GL-AR750S OEM U-Boot allows upload and flashing of either NOR
firmware (sysupgrade.bin) or NAND firmware (factory.img) through its
HTTP-based GUI. Serial connectivity is not required.
The glinet,gl-ar750s-nor and glinet,gl-ar750s-nor-nand images
generated after this commit flash each other directly.
This commit changes the control of the USB VBUS to gpio-hog from
regulator-fixed introduced by commit 0f6b944c92. This reduces the
compressed kernel size by ~14 kB, with no apparent loss of
functionality. No other ath79-nand boards are using regulator-fixed
at this time.
Note: mtd_get_mac_binary art 0x5006 does not return the proper MAC
and the GL.iNet source indicates that only the 0x0 offset is valid
The ar71xx targets are unmodified.
