Recommendations: Configure and link your PLC with OEM firmware
BEFORE you flash the device. PLC configuration/link should
remain in different memory and should work straight forward
after flashing.
Restrictions: PLC link detection to trigger plc red led is not
available. PLC G.hn chip is not compatible with open-plc-tools,
it uses LCMP protocol with AES-128 and requires different
software.
Notes: Pairing should be possible with gpio switch. Default
configuration will trigger wifi led with 2.4Ghz wifi traffic
and plc white led with wan traffic.
Flash instruction (TFTP):
1. Set PC to fixed ip address 192.168.0.100
2. Download the sysupgrade image and rename it to uploadfile
3. Start a tftp server with the image file in its root directory
4. Turn off the router
5. Press and hold Reset button
6. Turn on router with the reset button pressed and wait ~15 seconds
7. Release the reset button and after a short time
the firmware should be transferred from the tftp server

Currently bootloader always stays on the same version as when first
written to boot medium (not true if partition layout changed, which will
trigger sysupgrade process to write full disk image). That creates
inconveniences as it always stays with same features or/and bugs. Users
wishing to add support to additional modules or new version, would need
to write the whole image, potentially destroying previous system
configuration. To fix these, this commit adds additional routine to
sysupgrade which upgrades unconditionally the bootloader to the latest
state provided by OpenWrt.

Important Notes
===============
0. NOR Flash (2 MiB) is not touched by OpenWrt installation.
1. NAND Flash (128 MiB) layout under OpenWrt is changed as follows:
all space is split between 4 MiB kernel and 124 MiB UBI areas;
vendor partitions (language and mtdoops) are removed; kernel space
size can be further expanded if needed; maximum image size is set
to 25600k for compatibility reasons and can also be increased.
2. CPU clock is 775 MHz, not 750 MHz.
3. 5 GHz wireless radio chip is Atheros AR9580-AR1A with bogus PCI
device ID 0xabcd. For ath9k driver to load successfully, this is
overriden in DTS with correct value for this chip, 0x0033.
4. RFKILL button is wired to AR9580 pin 9 which is normally disabled
by chip definition in ath9k code (0x0000F4FF gpio mask). Therefore
'qca,gpio-mask=<0xf6ff>' hack must be used for button to work
properly.
5. USB port is always on, no GPIO for 5V power control has been
identified.

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.

The GL.iNet GL-AR300M series of devices includes variants without NAND
and only the 16 MB NOR flash. These include the GL-AR300M16 and the
GL-AR300M-Lite (already with its own board name).
This board-name addition provides disambiguation from the NAND-bearing
GL-AR300M devices, both for OpenWrt code and for end users.
Kernel and firmware support for NAND and UBI will add ~320 kB to the
overall firmware size at this time. This NOR-only option continues to
provide more compact firmware for both the GL-AR300M16 as well as
those who wish to use it as an alternate or primary, NOR-resident
firmware on the GL-AR300M.
The ar71xx targets are unmodified.
Installation
------------
Install through OEM U-Boot (HTTP-based) or `sysupgrade --force` when
booted from NOR and running OEM or OpenWrt, NOR-based firmware.
As one of the intentions is disambiguation from NAND-bearing units,
users who have flashed this firmware onto a device with NAND would
need to use U-Boot or `sysupgrade --force` to flash firmware that
again supports NAND.
There are no additional SUPPORTED_DEVICES as it is not possible to
determine if a device does or does not have NAND based on
either the OEM's or OpenWrt's board names prior to this patch.

1. Grab the uboot for the Device from the 'u-boot-fritz1200'
subdirectory. Place it in the same directory as the 'eva_ramboot.py'
script. It is located in the 'scripts/flashing' subdirectory of the
OpenWRT tree.
2. Assign yourself the IP address 192.168.178.10/24. Connect your
Computer to one of the boxes LAN ports.
3. Connect Power to the Box. As soon as the LAN port of your computer
shows link, load the U-Boot to the box using following command.
> ./eva_ramboot.py --offset 0x85000000 192.168.178.1 uboot-fritz1200.bin
4. The U-Boot will now start. Now assign yourself the IP address
192.168.1.70/24. Copy the OpenWRT initramfs (!) image to a TFTP
server root directory and rename it to 'FRITZ1200.bin'.
5. The Box will now boot OpenWRT from RAM. This can take up to two
minutes.
6. Copy the U-Boot and the OpenWRT sysupgrade (!) image to the Box using
scp. SSH into the Box and first write the Bootloader to both previous
kernel partitions.
> mtd write /path/to/uboot-fritz1200.bin uboot0
> mtd write /path/to/uboot-fritz1200.bin uboot1
7. Remove the AVM filesystem partitions to make room for our kernel +
rootfs + overlayfs.
