ipq806x: add missing enclosing reserved-memory block on C2600/AD7200
Most of the time when booting kernel prints a warning from
mm/page_alloc.c when pstore/ramoops is being initialized and ramoops is
not functional.

Fix this by moving ramopps node into reserved-memory block as described
in kernel documentation.

ipq806x: onhub: Enable fstools_partname_fallback_scan
When fstools is unable to parse our root=<...> arg correctly, it can
fall back to scanning all block devices for a 'rootfs_data' partition.
This fallback was deemed wrong (or at least, a breaking/incompatible
change) for some targets, so we're forced to opt back into it with
fstools_partname_fallback_scan=1.

Without this, OnHub devices will use a rootfs-appended loop device for
rootfs_data instead of the intended 3rd partition.

While I'm at it, just move all the boot args into the 'cros-vboot'
build rule, instead of using the custom bootargs-append. All cros-vboot
subtargets here are using the same rootwait (to support both eMMC and
USB boot) and root/partition args.

ipq806x: Initial TP-Link and ASUS OnHub support
TP-Link and ASUS OnHub devices are very similar, sharing many of the
same characteristics and much of their Device Tree. They both run a
version of ChromeOS for their factory firmware, and so installation
instructions look very similar to Google Wifi [1].

Things I've tested, and are working:

 * Ethernet
 * WiFi (2.4 and 5 GHz)
 * LEDs
 * USB
 * eMMC
 * Serial console (if you wire it up yourself)
 * 2x CPU
 * Speaker

== Installation instructions summary ==

1. Flash *-factory.bin to a USB drive (e.g., with `dd`)
2. Insert USB drive, to boot OpenWrt from USB
3. Copy the same *-factory.bin over to device, and flash it to eMMC to
   make OpenWrt permanent

== Developer mode, booting from USB (Step 2) ==

To enter Developer Mode and boot OpenWrt from a USB stick:

1. Unplug power
2. Gain access to the "developer switch" through the bottom of the
   device
3. Hold down the "reset switch" (near the USB port / power plug)
4. Plug power back in
5. The LED on the device should turn white, then blink orange, then
   red. Release the reset switch.
6. Insert USB drive with OpenWrt factory.bin
7. Press the hidden developer switch under the device to boot to USB;
   you should see some activity lights (if you have any) on your USB
   drive
8. Depending on your configuration, the router's LED(s) should come on.
   You're now running OpenWrt off a USB stick.

These instructions are derived from:

https://www.exploitee.rs/index.php/Rooting_The_Google_OnHub#Enabling_%22Developer_Mode%22_on_the_OnHub
https://www.exploitee.rs/index.php/Asus_OnHub#Enabling_%22Developer_Mode%22_on_the_OnHub

~~Finding the developer switch:~~ for TP-Link, the developer switch is
on the bottom of the device, underneath some of the rubber padding and a
screw. For ASUS, remove the entire base, via 4 screws under the rubber
feet. See the Exploitee instructions for more info and photos.

== Making OpenWrt permanent (on eMMC) (Step 3) ==

Once you're running OpenWrt via USB:

1. Connect Ethernet to the LAN port; router's LAN address should be at
   192.168.1.1
2. Connect another system to the router's LAN, and copy the factory.bin
   image over, via SCP and SSH:

     scp -O openwrt-ipq806x-chromium-tplink_onhub-squashfs-factory.bin root@192.168.1.1:
     ssh root@192.168.1.1 -C "dd if=/dev/zero bs=512 seek=7552991 of=/dev/mmcblk0 count=33 && \
     dd if=/root/openwrt-ipq806x-chromium-tplink_onhub-squashfs-factory.bin of=/dev/mmcblk0"
3. Reboot and remove the USB drive.

== Developer mode beep ==

Note that every time you boot the OnHub in developer mode, the device
will play a loud "beep" after a few seconds. This is described in the
Chromium docs [2], and is intended to make it clear that the device is
not running Google software. It is nontrivial to completely disable this
beep, although it's possible to "acknowledge" developer mode (and skip
the beep) by using a USB keyboard to press CTRL+D every time you boot.

ipq806x: 5.15: standardize wpq864 partition table
Compex WPQ864 contains a non standard partition table. Each partition
node should be named partition and should contain a valid reg.
Fix an extra "-" present after the reg for SBL2_1 partition.

Also add "0:" to each qcom default partition following smem naming.

ipq806x: 5.15: fix wrong boot-partitions values for split partitions
The refreshed patch actually use the format of <start size start size>
instead of <start end start end>. This cause boot fail since the rootfs
can't be mounted with these wrong values.

The patch has changed implementation and now the binding has changed.
Replace the old binding with boot-partitions and reimplement the
definition with the new definition.
The new definition is:
<offset1 size1 offset2 size2 offset3 ...>
and now supports sparsed patch.

Also add missing binding in some dts and add the backup boot partition
to the boot-partitions list.
