7a21c85f70 ramips: improve support for Xiaomi Miwifi Nano
This patch does the following things:
1. mark u-boot-env writable
2. add bootcount support
   Currently, u-boot has a flag_boot_success env variable to reset.
   Also reset it in our firmware to follow the behavior in vendor's
   firmware.
3. disable usb support
   This router doesn't have usb port at all.
4. increase spi clock to 40MHz
5. fix pinmux groups

9d87a58d34 ramips: remove ralink_default_fw_size_xxx variables
There are frequent examples of the ralink_default_fw_size_xxx
variables being used to "roughly" set flash size without caring
about the actual size of the firmware partition.

To discourage this behavior, this patch removes the variables and
just sets IMAGE_SIZE by its numeric value for each target.

363197311b ramips: remove default IMAGE_SIZE for ramips target
Currently, ramips target defines 0x7b0000 as default IMAGE_SIZE
for all devices in ramips target, i.e. this will be set if a
device does not specify IMAGE_SIZE itself.

From 92 devices using that default due to a "missing" IMAGE_SIZE,
14 were incorrect by a small amount (i.e. still "8M" flash) and
12 were completely off ("16M", "4M", ...).

This patch thus removes the _default_ IMAGE_SIZE and defines
IMAGE_SIZE for each device individually. This should indicate to
people supporting new devices that this parameter has to be cared
about.

For the present code, this patch is cosmetical.

7392af7520 ramips: fix ralink_default_fw_size_16M
In ramips, there are the following predefined values for IMAGE_SIZE
ralink_default_fw_size_4M    3866624   3776k   0x3B0000
ralink_default_fw_size_8M    8060928   7872k   0x7B0000
ralink_default_fw_size_16M  16121856  15744k   0xF60000
ralink_default_fw_size_32M  33226752  32448k  0x1FB0000

Out of those, the "16M" value is obviously odd, as it provides more
room for the remaining partitions than the tree others.
Of the devices in all subtargets, there are actually > 50 that have
a firmware partition with 0xFB0000 size, while only 5 (!) have
0xF60000. From the former, many are set to
ralink_default_fw_size_16M anyway, although it is wrong at the
present point.

Consequently, it makes sense to change ralink_default_fw_size_16M
to 0xFB0000, and to update IMAGE_SIZE for the 5 devices with
0xF60000.

- 1x SIM slot

Flash instruction:
U-boot has a builtin web recovery page:
1. Hold the reset button while powering it up
2. Connect to the ethernet and set an IP in 192.168.1.0/24 range
3. Open your browser and upload firmware through http://192.168.1.1

Note about the LTE modem:
If your router comes with an EC25 module and it doesn't show up
as a QMI device, you should do the following to switch it to QMI
mode:
1. Install kmod-usb-serial-option and a terminal software
   (e.g. minicom or screen). All 4 serial ports of the modem
   should be available now.
2. Open /dev/ttyUSB3 with the terminal software and type this
   AT command: AT+QCFG="usbnet",0
3. Power-cycle the router. You should now get a QMI device
   recognized.

7c91144ae6 ramips: add CUDY WR1000 support
Cudy WR1200 is an AC1200 AP with 3-port FE and 2 non-detachable antennas

Specifications:

MT7628 (580 MHz)
64 MB of RAM (DDR2)
8 MB of FLASH
2T2R 2.4 GHz (MT7628)
2T2R 5 GHz (MT7612E)
3x 10/100 Mbps Ethernet (2 LAN + 1 WAN)
2x external, non-detachable antennas (5dbi)
UART header on PCB (57600 8n1)
7x LED, 2x button

Known issues:
The Power LED is always ON, probably because it is connected
directly to power.

Flash instructions
------------------
Load the ...-factory.bin image via the stock web interface.

Openwrt upgrade instructions
----------------------------
Use the ...-sysupgrade.bin image for future upgrades.

Revert to stock FW
------------------
Warning! This tutorial will work only with the following OEM FW:
  WR1000_EU_92.122.2.4987.201806261618.bin
  WR1000_US_92.122.2.4987.201806261609.bin
If in the future these firmwares will not be available anymore,
you have to find the new XOR key.

1) Download the original FW from the Cudy website.

   (For example WR1000_EU_92.122.2.4987.201806261618.bin)

2) Remove the header.

   dd if="WR1000_EU_92.122.2.4987.201806261618.bin" of="WR1000_EU_92.122.2.4987.201806261618.bin.mod" skip=8 bs=64

3) XOR the new file with the region key.

   FOR EU: 7B76741E67594351555042461D625F4545514B1B03050208000603020803000D
   FOR US: 7B76741E675943555D5442461D625F454555431F03050208000603060007010C

   You can use OpenWrt's tools/firmware-utils/src/xorimage.c tool for this:

   xorimage -i WR1000..bin.mod -o stock-firmware.bin -x -p 7B767..

   Or, you can use this tool (CHANGE THE XOR KEY ACCORDINGLY!):
   https://gchq.github.io/CyberChef/#recipe=XOR(%7B'option':'Hex','string':''%7D,'',false)

4) Check the resulting decrypted image.

   Check if bytes from 0x20 to 0x3f are:
   4C 69 6E 75 78 20 4B 65 72 6E 65 6C 20 49 6D 61 67 65 00 00 00 00 00 00 00 00 00 00 00 00 00 00

   Alternatively, you can use u-boot's tool dumpimage tool to check
   if the decryption was successful. It should look like:

   # dumpimage -l stock-firmware.bin
   Image Name:   Linux Kernel Image
   Created:      Tue Jun 26 10:24:54 2018
   Image Type:   MIPS Linux Kernel Image (lzma compressed)
   Data Size:    4406635 Bytes = 4303.35 KiB = 4.20 MiB
   Load Address: 80000000
   Entry Point:  8000c150

5) Flash it via forced firmware upgrade and don't "Keep Settings"

   CLI: sysupgrade -F -n stock-firmware.bin

   LuCI: make sure to click on the "Keep settings" checkbox
         to disable it. You'll need to do this !TWICE! because
         on the first try, LuCI will refuse the image and reset
	 the "Keep settings" to enable. However a new
         "Force upgrade" checkbox will appear as well.
         Make sure to do this very carefully!

Create Factory image
--------------------
As all installation methods require a U-Boot to be integrated into the
Image (and we do not ship one with the image) we are not able to create
an image in the OpenWRT build-process.

Download a TP-Link image from their Wesite and a OpenWRT sysupgrade
image for the device and build yourself a factory image like following:

TP-Link image:             tpl.bin
OpenWRT sysupgrade image:  owrt.bin

 > dd if=tpl.bin of=boot.bin bs=131584 count=1
 > cat owrt.bin >> boot.bin

Installing via Web-UI
---------------------
Upload the boot.bin via TP-Links firmware upgrade tool in the
web-interface.

Installing via Recovery
-----------------------
Activate Web-Recovery by beginning the upgrade Process with a
Firmware-Image from TP-Link. After starting the Firmware Upgrade,
wait ~3 seconds (When update status is switching to 0%), then
disconnect the power supply from the device. Upgrade flag (which
activates Web-Recovery) is written before the OS-image is touched and
removed after write is succesfull, so this procedure should be safe.

Plug the power back in. It will come up in Recovery-Mode on 192.168.0.1.
When active, all LEDs but the WPS LED are off.
Remeber to assign yourself a static IP-address as DHCP is not active in
this mode.

The boot.bin can now be uploaded and flashed using the web-recovery.

Installing via TFTP
-------------------
Prepare an image like following (Filenames from factory image steps
apply here)

 > dd if=/dev/zero of=tp_recovery.bin bs=196608 count=1
 > dd if=tpl.bin of=tmp.bin bs=131584 count=1
 > dd if=tmp.bin of=boot.bin bs=512 skip=1
 > cat boot.bin >> tp_recovery.bin
 > cat owrt.bin >> tp_recovery.bin

Place tp_recovery.bin in root directory of TFTP server and listen on
192.168.0.66/24.

Connect router LAN ports with your computer and power up the router
while pressing the reset button. The router will download the image via
tftp and after ~1 Minute reboot into OpenWRT.

U-Boot CLI
----------
U-Boot CLI can be activated by holding down '4' on bootup.

Dual U-Boot
-----------
This is the first TP-Link MediaTek device to feature a split-uboot
design. The first (factory-uboot) provides recovery via TFTP and HTTP,
jumping straight into the second (firmware-uboot) if no recovery needs
to be performed. The firmware-uboot unpacks and executed the kernel.

Web-Recovery
------------
TP-Link integrated a new Web-Recovery like the one on the Archer C7v4 /
TL-WR1043v5. Stock-firmware sets a flag in the "romfile" partition
before beginning to write and removes it afterwards. If the router boots
with this flag set, bootloader will automatically start Web-recovery and
listens on 192.168.0.1. This way, the vendor-firmware or an OpenWRT
factory image can be written.

By doing the same while performing sysupgrade, we can take advantage of
the Web-recovery in OpenWRT.

It is important to note that Web-Recovery is only based on this flag. It
can't detect e.g. a crashing kernel or other means. Once activated it
won't boot the OS before a recovery action (either via TFTP or HTTP) is
performed. This recovery-mode is indicated by an illuminated WPS-LED on
boot.

Change the code to append header and footer in two steps. Allow to use a

Use a fixed timestamp within the zip archive to make the images
reproducible.

Due to the changes we are now compatible to the gnu89 c standard used by
default on the buildbots and we don't need to force a more recent
standard anymore.

Beside all changes, the footer still looks wrong in compare to the

33321ebefa ramips: TP-Link TL-WR902AC v3: don't build factory image
The line that produces factory image was accidentally left by me while
testing before inital commit.

I came to the conclusion that flashing from OEM firmware does not work
(seems to share this behavior with other tplinks based on mt7628).

I have not done any further analysis, as I was unable to open the
case and attach a serial port (too much glue). Maybe i will try once
more.

So the way to do initial flashing (or un-bricking) is to use the
tftp-recover image. It is possible to revert to OEM firmware with tftp
recovery; in this case the first 512 bytes the image file need to be
cut off.
