c4fdb377a2 Revert "ipq806x: fix EA8500 switch control"
There is a problem with the EA8500, the switch will not work after soft
reboot, the only way to get it working again is to power cycle it
manually.

There are probably several issues in the play, it's quite hard to fix it
without having access to the actual device, so I don't see any other
option now, then revert the offending commit.

57b1e951b5 ipq806x: Enlarge R7500v2 flash - use netgear partition
This patch increases available space from 20MB to 86MB.
Netgrear OEM firmware contains a 'netgear' partition followed 'ubi',
which can be used in openwrt for larger ubi space. (similar to
Netgear R7800).

original author (notmyrealhandle) tested this on R7500v2 and point that
OEM firmware can auto rebuild this partition (if used by openwrt).

064e431575 ipq8064: Enabling sata port ipq8064 based devices
(original text here: https://patchwork.kernel.org/patch/8686761/)

On some SOCs PORTS_IMPL register value is never programmed by the BIOS
and left at zero value. Which means that no sata ports are avaiable for
software. AHCI driver used to cope up with this by fabricating the
port_map if the PORTS_IMPL register is read zero, but recent patch
broke this workaround as zero value was valid for nvme disks.
This patch adds ports-implemented dt bindings as workaround for this issue
in a way that DT can dictate the port_map incase where the SOCs does not
program it already.

This patch is equal to commits:
67f8425d0ee1 ("ipq8064: dts: force AP148 SATA port mapping")
2e7a2c91019c ("ARM: dts: qcom: Move common nodes to ipq8064-v.1.0.dtsi")

In DTS Checklist[1] we're now demanding proper generic node names, as

51fe956c4f ipq806x: add support for Buffalo WXR-2533DHP
Buffalo WXR-2533DHP is a 2.4/5 GHz band 11ac router, based on Qualcomm
IPQ8064.

The U-Boot on WXR-2533DHP employs a complicated dual firmware
protection scheme against corruptions of the kernel and rootfs
images. See the notes in buffalo.sh for details.

specifications:

- Qualcomm IPQ8064 (384 - 1,400 MHz, 2C2T)
- 512 MB of RAM (DDR3)
- 256 MB of Flash (NAND)
- 4T4R 2.4/5 GHz Wlan (QCA9980)
- 5x 10/100/1000 Mbps Ethernet
- 10x LEDs, 8x keys (6x buttons, 2x slide-switches)
- 2x USB 3.0 Type-A
- 12VDC/4A AC Adapter
- UART through-hole on PCB
  - J3: Vcc, GND, TX, RX from USB port side
  - 115200n8

Boot instructions for the initramfs image:

1. Prepare the TFTP server with the initramfs image renamed to
   "wxr2300dhp-initramfs.uImage" and IP address "192.168.11.10".
2. Press the "AOSS" button while powering on the WXR-2533DHP.
3. Wait until the "Wireless" LED flashes before releasing the AOSS button.
   The WXR-2533DHP will grab the image from TFTP server and will boot it.

Flashing instructions:

To persistently write the firmware, flash an openwrt sysupgrade image
from inside the initramfs, for example transfer
via `scp <sysupgrade> root@192.168.1.1:/tmp` and flash on the device
with `sysupgrade -n /tmp/<sysupgrade>`. Then wait ~120 seconds to
let it finish the flashing process.

7b74b40fe9 ipq806x: remove "firmware" partition definition from netgear routers
Remove the "firmware" partition definition from the DTS of R7800
to fix sysupgrade.

Commit 4645a6d3 defined CONFIG_MTD_SPLIT_UIMAGE_FW=y for ipq806x
and that causes mtd to misbehave as additional kernel and ubi
partitions are detected from inside the "firmware" partition.
  [    1.111324] 0x000001480000-0x000001880000 : "kernel"
  [    1.121005] 0x000001880000-0x000007900000 : "ubi"
  [    1.283912] 0x000007900000-0x000008000000 : "reserve"
  [    1.296407] 0x000001480000-0x000007900000 : "firmware"
  [    1.468043] no rootfs found after FIT image in "firmware"
  [    2.426860] 2 uimage-fw partitions found on MTD device firmware
  [    2.426931] 0x000001480000-0x000001880000 : "kernel"
  [    2.440420] 0x000001880000-0x000007900000 : "ubi"

Both kernel and ubi are already defined in DTS, so this duplication
leads into errors in sysupgrade:
  Writing from <stdin> to kernel ...
  ubiattach: error!: strtoul: unable to parse the number '6 mtd10'
  ubiattach: error!: bad MTD device number: "6 mtd10"

The partition is defined to same area as kernel+ubi, and is not
needed for sysupgrade anymore. Remove it to fix things.

Only tested for the R7800 but all of them should behave equal.

fb8a578aa7 ipq806x: Enlarge R7800 flash - use netgear partition
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

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.

45b8a7c1a6 ipq806x: increase kernel partition size for the Netgear Nighthawk X4 D7800
Starting with kernel 4.14 and gcc 7, the kernel doesn't fit into the
2 MB reserved for the kernel partition by the OEM firmware anymore.

This patch increases the kernel partition from 2 MB to 4 MB, at the
expense of the rootfs, for all supported kernels.

WARNING: This breaks sysupgrade! Flashing a firmware containing this
changed partitioning from an older image with 2 MB reserved for the
kernel partion requires the tftp recovery procedure, thereby losing
all settings.

This change follows the functional example of the Netgear r7800, but
has not been runtime tested on a Netgear Nighthawk X4 D7800.

0c967d92b3 ipq806x: increase kernel partition size for the TP-Link Archer VR2600v
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.

This change follows the example for the TP-Link Archer C2600, but has
not been runtime tested on a TP-Link Archer VR2600v.

The default image does not fit 2 MB anymore, expand os-image partition
to 4 MB.

Upgrading works transparently via sysupgrade in both directions.
Another option would have been to merge "os-image" 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
and actually tested on an affected device; the maximum for rootfs
changes from 27 MB to 25 MB.

Run-tested on TP-Link Archer C2600.
