The current make-ras.sh image generation script for the ZyXEL NBG6617
has portability issues with bash. Because of this, factory images are
currently not built correctly by the OpenWRT buildbots.
This commit replaces the make-ras.sh by C-written mkrasimage.
The new mkrasimage is also compatible with other ZyXEL devices using
the ras image-format.
This is not tested with the NBG6616 but it correctly builds the
header for ZyXEL factory image.

The upgrade led is only used if a running led is defined. If no running
led is defined, the upgrade led is ignored and upgrade isn't indicated
at all.
Instead, turn off the running led prior to turning the upgrade led on.
In most cases there isn't any visual change, but it allows to use an

The original device support patch configured the amber wlan LEDs (which
are meant as error indicator by the OEM) controlled by the SOC's GPIO
as wlan traffic indicators, as the correct white wlan LEDs are
connected to GPIOs controlled by the QCA9984/ ath10k wlan cards were
not accessible. The recent addition of GPIO/ LED support to ath10k now
makes it possible to use the correct white LEDs instead - and
"mac80211: ath10k: use tpt LED trigger by default" also enables them by
default. While both LEDs are independent of each other (two separate
LEDs sharing one light tunnel), triggering both on wlan traffic is not
the intended behaviour (bright yellow light).

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"

[ 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.

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

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.

The default image does not fit 2 MB anymore, expand kernel partition

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

- SIM Card Slot: 2 x Slot

- LEDs: 18x, 8x GPIO controllable

The correct amount of RAM will be passed by the bootloader.
In contrast to the documentation provided by Compex, the third PCIe
doesn't use GPIO16 for PERST. Instead, GPIO3 is shared and used as PERST
for PCIe0 and PCIe2.
So far, no one was able to get USB 3.0 working with the 1GB RAM version,
while it works fine for my 512MB version. Since USB 3.0 doesn't work with
the Compex firmware for the 1G variant either, it could be a hardware
issue with these boards.
OpenWrt will be installed to the NAND flash. Make sure to have a full
working image on the NOR flash. It will be the backup in case anything
goes wrong.
It has been observed that an image loaded via tftpboot might have
bitflips. Hence the extra step to create a crc32 checksum to allow to
compare the checksum with the one from the source file prior to flashing.
In all cases it is necessary to set the following u-boot parameter to an
empty (whitespace) value, to ensure that the chosen bootargs of the dts
isn't overwritten or set to bogus - not working - values:
(IPQ) # set bootargs " "
(IPQ) # set fsbootargs " "
(IPQ) # saveenv
The sysupgrade image can be installed directly on flash using u-boot (put
jumper in JP13 (leave JP9 open) to boot from nand):
(IPQ) # set serverip 192.168.1.20
(IPQ) # set ipaddr 192.168.1.1
(IPQ) # tftpboot 0x42000000 openwrt-ipq806x-compex_wpq864-squashfs-nand-factory.bin

Instead of writing to the currently booted partition set, this
implements full dual-boot support for sysupgrade by always writing to
the other, currently inactive, partition set and toggling the dualflag
after a successful flash.
The currently active/ booted partition set is determined by parsing
/proc/cmdline for its rootfs parameter (supplied by the DTS), instead
of reading from the 0:DUAL_FLAG mtd, in order to prevent (potentially)
bricking both partition sets.

Instead of hardcoding /dev/loop0, it's safer to query for the first
free loop device and assign that dynamically. While /dev/loop0 is a
reasonable assumption immediately following "losetup --detach-all",
detaching the mounted overlay is no longer strictly necessary once
dual-boot support has been added for the nbg6817.
