9cd69c45c5 firmware-utils: tplink-safeloader: add TP-Link Archer C25 v1
This adds the necessary firmware layout definitions for the Archer C25.
It has an addtional partition containing some static data ("extra-para")
without which no factory flash is possible, therefore put_data() has been
added.

b7cc661615 ar71xx: add support for TP-Link TL-WR942N v1
TP-Link TL-WR942N v1 is a 2.4 GHz single-band N450 router, based on
Qualcomm/Atheros QCA9561.

Specification:

- 775/650/258 MHz (CPU/DDR/AHB)
- 128 MB of RAM (DDR2)
- 16 MB of FLASH (SPI NOR)
- 3T3R 2.4 GHz
- 5x 10/100 Mbps Ethernet
- 2x USB 2.0
- 11x LED (most are controlled by 74HC595)
- 2x button
- UART header on PCB*

* Serial console is disabled in OEM non-beta firmwares and corresponding
  GPIO pins 14 and 15 are assigned to control USB1 and USB2 LEDs by
  production (non-beta) U-Boot and firmware.

Currently not working:

1. USB1 and USB2 LEDs if UART RX and TX pins are assigned to their GPIOs
   by some U-Boot versions.

Flash instruction under vendor GUI:

1. Download "lede-ar71xx-generic-tl-wr942n-v1-squashfs-factory.bin".
2. Go to WEB interface and perform usual firmware upgrade.

FLash instruction under U-Boot recovery mode (doesn't work in beta
firmware):

1. Setup PC with static IP "192.168.0.66/24" and tftp server.
2. Change "*-factory" image filename to "WR942v1_recovery.bin" and make
   it available to download from your tftp server.
3. Press "reset" button and power up the router, wait till "WPS" LED
   turns on.

Flash instruction under U-Boot, using UART (can be done only with
preinstalled UART-enabled U-Boot version!):

1. Use "tpl" to stop autobooting and obtain U-Boot CLI access.
2. Setup ip addresses for U-Boot and your tftp server.
3. Issue below commands:
   tftp 0x81000000 lede-ar71xx-generic-tl-wr942n-v1-sysupgrade.bin
   erase 0x9f020000 +$filesize
   cp.b 0x81000000 0x9f020000 $filesize
   reset

c4022243d8 firmware-utils: tplink-safeloader: support strings as soft_version
Some TP-Link routers (C25, C59, C60) contain a version string instead
of a binary structure in the soft_version partition.

Flashing LEDE from the original firmware's GUI, this version string
taken from the soft_ver partition of the firmware image is written to
the router's config partition.

When using tftp recovery to go back to the original Archer C25 firmware,
a version check compares that version to the version of the firmware to
be flashed.

Without proper contents in the config partition, reverting to the
original firmware fails.

Therefore, write the string "soft_ver:1.0.0\n" to that soft_ver
partition.

56561b9f51 ar71xx: add support for TP-Link TL-WA850RE v2
TP-Link TL-WA850RE v2 is a wall-plug N300 Wi-Fi range extender,
based on Qualcomm/Atheros QCA9533 v2.

Short specification:

- 550/391/195 MHz (CPU/DDR/AHB)
- 1x 10/100 Mbps Ethernet
- 32 MB of RAM (DDR1)
- 4 MB of FLASH
- 2T2R 2.4 GHz
- 2x internal antennas (embedded on PCB)
- 9x LED (all can be turned off with GPIO15), 2x button
- UART (J3) header on PCB

Flash instruction: use "factory" image directly in vendor GUI.

Warning: this device does not include any kind of recovery mechanism
in the bootloader and disassembling process is not trivial.

You can access vendor firmware over serial line using:
- login: root
- password: sohoadmin

Image was tested only in US version of the device, but should work
also with the same device version sold in other countries.

Available FLASH space, with LEDE trunk, is only 240 KB.

0d9d980ecd firmware-utils: kernel image generator for TP-Link RE450
The firmware image that is used in TP-Link RE450 (and some more devices from
the RE series) is tplink-safeloader.
In the kernel partition, the kernel is compressed in a regular tp-link
firmware that is just used for booting. Since it is only used for compressing
and booting, only four fields are filled in the header:
Vendor, version, kernel load address and kernel entry point.
mktplinkfw-kernel is a simpler version of mktpolinkfw that generate such
images. It also specifies the hardware id (as it is in the product info
section), so when doing a sysupgrade - the existing code will check for
hardware compatibility.

cb7ab730c7 firmware-utils: replace md5 code with Alexander Peslyak's implementation
Our current implementation is pretty old and uses some pre-standard/old
ANSI C style that triggers warnings like:
warning: call to function 'MD5_Init' without a real prototype [-Wunprototyped-calls]

This is caused by declarations specified in a following way:
src/md5.h:60:6: note: 'MD5_Init' was declared here
 void MD5_Init ();

Having these warnings makes it harded to notice real problems. We could
try hiding them but it makes more sense to just use a cleaner code.
Another tiny gain from this switch is slightly reduced binary size, on
x86_64 tplink-safeloader's size 48104 became 48003.

The new code is public domain, uses "heavily cut-down BSD license".

This patch adds header support for the Cisco Meraki MX60/MX60W, which

due to the fact this device uses U-Boot (unlike other devices in

offsets for the image.

A thanks to Christian for helping implement this properly.

0d3be662ce firmware-utils: tplink-safeloader: keep per-device info on trailing char
Recent refactoring introduced a regression. It ignored second argument
of make_support_list function which was originally true for C2600. The
new generic build_image function always passes false.

This patch allows specifying trailing char in a device specific info. It
also switches Archer C9 to the \0 char to make it compliant with vendor
images.

I verified generated images to be binary identical to the ones that
were created before whole refactoring.

00d1e6c75e firmware-utils: fix compilation on MacOS X
Looking into /usr/include/stdlib.h, there's a `devname()` function defined
under some #ifdef's which conflicts with the `static char *devname` definition
in `src/mkwrggimg.c`.

Defining `_ANSI_SOURCE` in the `src/mkwrggimg.c` file, omits that part of the
header.

Another more intrusive approach is to rename `devname` to something like
`g_devname` in `src/mkwrggimg.c`. But I think the `_ANSI_SOURCE` define should
be enough.

Compilation error is:

    src/mkwrggimg.c:64:14: error: redefinition of 'devname' as different kind of symbol

076d58d344 firmware-utils: mkfwimage: fix firmware_max_length for XM layout
The new u-boot version bundled with the 5.6.x firmwares from Ubiquiti gets
confused by the smaller rootfs partition size; this can lead to various
issues:

1. We've gotten reports that flashing from the 5.6.x stock firmware to
   OpenWrt will brick devices; I wasn't able to reproduce this myself
2. Flashing from 5.5.x stock firmware to OpenWrt and back to stock (via
   TFTP recovery), following by an update to 5.6.x via web interface can
   yield a bricked device with the following properties:
   - It can't be booted without entering commands over a serial console, as
     u-boot supplies the wrong MTD layout
   - The web interface won't accept any image with the original flash
     layout, so stock firmware upgrades are impossible
   - As the TFTP recovery doesn't update u-boot, returning to the old
     u-boot from firmware 5.5.x is impossible

To recover from 2., creating an OpenWrt image which doesn't set u-boot as
read-only and flashing a backup of the old u-boot from there is the only
way known to me. (Fixing the mtdparts variable in u-boot-env from OpenWrt
might also work; settings this from u-boot over serial didn't have
any permanent effect.)

Fix all of this by setting the correct flash layout also used by the stock
firmware. Flashing has been tested from both firmware 5.5.x and 5.6.x. The
fixed layout also matches the mtdparts defined by OpenWrt.
