Increase the available flash memory size in Netgear R7800
by taking into the use the unused "netgear" partition
that is located after the firmware partition.
Available flash space for kernel+rootfs+overlay increases
by 68 MB from 32 MB to 100 MB.
In a typical build, overlay space increases from 15 to 85,
increasing the package installation possibilities greatly.
Reverting to the OEM firmware is still possible, as the OEM
firmware contains logic to initialise the "netgear" partition
if its contents do not match expectations. In OEM firmware,
"netgear" contains 6 UBI sub-partitions that are defined in
/etc/netgear.cfg and initialisation is done by /etc/preinit
Tested with Openwrt master r7093-4fdc6ca31b and OEM V1.0.2.52

NEC Aterm WG2600HP is a 2.4/5 GHz band 11ac router, based on Qualcomm
IPQ8064.
Specification:
- IPQ8064 (384 - 1,400 MHz)
- 512 MB of RAM
- 32 MB of Flash (SPI)
- 4T4R 2.4/5 GHz
- 5x 10/100/1000 Mbps Ethernet
- 12x LEDs, 4x keys
- 1x USB 3.0 Type-A
- UART header on PCB
- RX, TX, NC, GND, Vcc from power connector side
- baudrate: 115200 bps
Flash instruction using initramfs image:
1. Connect serial cable to UART header
2. Connect power cable and turn on the router
3. When the "Press the [f] key and hit [enter] to enter failsafe mode"
message is displayed on the console, press the "f" key and Enter key
sequentially to enter the failsafe mode
4. create fw_env.config file with following contents on failsafe mode:
/dev/mtd9 0x0 0x10000 0x10000
5. Execute following commands to add and change the environment
variables of U-Boot
fw_setenv ipaddr "192.168.0.1"
fw_setenv serverip "192.168.0.2"
fw_setenv autostart "yes"
fw_setenv bootcmd "tftpboot 0x44000000 wg2600hp-initramfs.bin;
bootipq"
6. Set the IP address of the computer to 192.168.0.2, connect to the LAN
port of WG2600HP, and start the TFTP server on the computer
7. Rename OpenWrt initramfs image for WG2600HP to
"wg2600hp-initramfs.bin" and place it in the TFTP directory
8. Remove power cable from WG2600HP, reconnect it and restart WG2600HP
9. WG2600HP downloads initramfs image from TFTP server on the computer,
loads it and boot with initramfs image
10. On the initramfs image, execute "mtd erase firmware" to erase stock
firmware and execute sysupgrade with the sysupgrade image
11. Wait ~180 seconds to complete flashing

EA8500 has pcie2 slot unequipped.
By EA8500 hw design default pcie2 reset gpio (gpio63) is used to
reset the switch. That's why enabling pcie2 brings the switch into
a working state.
So let's just control the gpio63 without enabling the pcie2 slot.
We have to remove the pcie2_pins node so the gpio63 is not defined
twice. Because pcie2 node has a reference to pcie2_pins we have to
remove it as well.

USB PHY power settings introduced for ipq8065 SoC with commit
644a0d5 "ipq8065: adjust SS USB PHY power settings"
According to that commit msg and in correspondence to GPL tarballs
and related QSDK branch those settings are applied to ipq8064
SoCs of version >= 2.0.
https://github.com/paul-chambers/netgear-r7800/blob/master/git_home/linux.git/sourcecode/arch/arm/mach-msm/board-ipq806x.c#L2507-L2514
Now as we have clarified that mass market boards are of SoC v2.0
move those USB PHY settings from ipq8065 (v3.0 SoC) dtsi to
ipq8064 v2.0 dtsi.

(cherry picked from commit e16f9abf6b)
According to OEM bootlog entry mass market devices are ipq8064 SoC
v2.0:
> socinfo_init: v6, id=202, ver=2.0, raw_id=2064, raw_ver=2064, hw_plat=0, hw_plat_ver=65536
I've checked C2600, EA8500 and VR2600v but couldn't find other
boards bootlog. I think it's safe to assume that other boards are
also v2.0. R7500 may be an exception because it was the first
device to hit the market.
So switch to v2.0 dtsi.

Starting with kernel 4.14 and gcc 7, the kernel doesn't fit into the

This patch increases the kernel partition from 2 MB to 4 MB, at the

WARNING: This breaks sysupgrade! Flashing a firmware containing this

(cherry picked from commit 45b8a7c1a6)
The default image does not fit 2 MB anymore, expand kernel partition
to 3 MB.
Upgrading should work transparently via sysupgrade in both directions.
Another option would be to merge "kernel" and "rootfs" into a single
"firmware" partition using MTD_SPLIT_TPLINK_FW, but just changing the
sizes of the existing partitioning has been deemed safer in the absence
of an actual runtime test on an affected device; the maximum for rootfs
changes from 10.4 MB to 9.4 MB.
