Specification:
- MT7629 CPU
- MT7531 switch
- MT7761N and MT7762N wifi
- 256 MB RAM
- 128 MB NAND flash with dual-boot partitions
- 2 buttons: WPS and reset
- 1 WAN port (1G)
- 4 LAN ports (1G)
- 1 USB port
Limitations (same as other MT7629/MT7761N/MT7762N devices):
- Wifi is not working
- Second core is not working (kernel error message "CPU1: failed to come online")
Disassembly:
- There are two screws under the front rubber feet and two under the label on the bottom (in the corners towards the back, you should be able to feel them).
Serial Interface:
- UART pin header is already soldered on the board. Pinning from front to back:
1 - VCC
2 - TX
3 - RX
4 - n/a
5 - GND
GPIO:
- 1 white LED, connected to GPIO 52
- 1 reset button, connected to GPIO 60
- 1 WPS button, connected to GPIO 58
MAC Adresses:
- The MAC address printed on the device label is used for LAN and WAN
- The MAC address is stored in the devinfo partition in ASCII format (hw_mac_addr=aa:bb:cc:dd:ee)
- 2.4 GHz wifi uses MAC of the device label + 1
- 5 GHz wifi uses MAC of the device label + 2
Flashing:
- OpenWrt is only runnig in the first partition of dual boot
- To ensure to be able to go back to the factory image, flash the last OEM firmware via OEM web interface. This will ensure that the OEM firmware is present on both partitions
- Because of dual boot partitions, flashing via OEM interface is not supported

- Router IP: 192.168.1.1
- TFTP server IP: 192.168.1.100
- TFTP file name: 7531.bin
- Open the device, connect UART and select " 1. System Load Linux to SDRAM via TFTP." during startup
- Adapt the settings to your environment, if required
- After initramfs is booted, flash the sysupgrade image
Return to OEM firmware:
- Run the following commands in OpenWrt to switch to the second partition
fw_setenv boot_part 2
fw_setenv bootimage 2
- Reboot the device. OEM firmware will start up again

This reduces open coding and allows to easily add a knob to enable
it treewide, where chosen packages can still opt-out via "no-lto".
Some packages used LTO, but not the linker plugin. This unifies 'em
all to attempt to produce better code.
Quoting man gcc(1):
"This improves the quality of optimization by exposing more code to the
link-time optimizer."
Also use -flto=auto instead of -flto=jobserver, as it's not guaranteed

This adds support for the Buffalo WSR-2533DHP2.
The device uses the Broadcom TRX image format with a special magic. To
be able to boot the images or load them they have to be wrapped with
different headers depending how it is loaded.
There are multiple ways to install OpenWrt on this device.
Boot ramdisk from U-Boot
----------------------------
This will load the image and not write it into the flash.
1. Stop boot menu with "space" key
2. Select "System Load Linux to SDRAM via TFTP."
3. Load this image:
openwrt-mediatek-mt7622-buffalo_wsr-2533dhp2-initramfs-kernel.bin
4. The system boots the image
Write to flash from U-Boot
-----------------------------
This will load the image over tftp and directly write it into the flash.
1. Stop boot menu with "space" key
2. Select "System Load Linux Kernel then write to Flash via TFTP."
3. Load this image:
openwrt-mediatek-mt7622-buffalo_wsr-2533dhp2-squashfs-factory-uboot.bin
4. The system writes this image into the flash and boots into it.
Write to flash from Web UI
-----------------------------
This will load the image over over the Web UI and write it into the flash
1. Open the Web UI
2. Go to "管理" -> "ファームウェア更新"
3. Select "ローカルファイル指定" and click "更新実行"
4. Load this image:
openwrt-mediatek-mt7622-buffalo_wsr-2533dhp2-squashfs-factory.bin
5. The system writes this image into the flash and boots into it.

Using the same method as the D-Link DAP-2695 A1 we use
the "mtd" tool to augment the firmware checkum in flash
on first boot of a new firmware on the D-Link DIR-685.
We need to augment the Makefile for "mtd" to build in
the special WRGG fixup support for Gemini as well.
This works around the problem of the machine not booting
after factory install unless the sysupgrade is applied
immediately.
Based on commit e3875350f3
"ar71xx: add support for D-Link DAP-2695 rev. A1"
Cc: Stijn Tintel <stijn@linux-ipv6.be>
Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
The D-Link DIR-685 has the same problem as the
D-Link DAP-2695: when flashing the factory image, the
checksum includes the whole flashed image, even the
rootfs_data part with the end of filesystem mark.
Also the whole flashed image is stored in the flash,
so on the first boot, the whole rootfs image is loaded
into memory with the kernel.
This is fixed using the fixwrgg command to mtd, but
for this to work we need to make fixwrgg work with
the Little-Endian ARM DIR-685.
The code tries to be endian agnostic but this fails
because the WRGG image loader doesn't. On ARM, the
file size is stored in little endian format, and on
big-endian systems it is stored in big endian format,
so we can just drop all the friendly htonl() that
will make the shdr->size big endian: this will
actually break the little endian systems, and on
the big endian systems the native endianness will
still be correct.
The magic number is always stored in little endian
format however, so make sure this is always read
in LE32 format. I chose to create a straight-forward
le32_to_cpu() static inline that IMO is simple and
easy to read.

Consistently handle boot-count reset and upgrade across
ipq40xx, ipq806x, kirkwood, mvebu
Dual-firmware devices often utilize a specific MTD partition
to record the number of times the boot loader has initiated boot.
Most of these devices are NAND, typically with a 2k erase size.
When this code was ported to the ipq40xx platform, the device in hand
used NOR for this partition, with a 16-byte "record" size. As the
implementation of `mtd resetbc` is by-platform, the hard-coded nature
of this change prevented proper operation of a NAND-based device.
* Unified the "NOR" variant with the rest of the Linksys variants
* Added logging to indicate success and failure
* Provided a meaningful return value for scripting
* "Protected" the use of `mtd resetbc` in start-up scripts so that
failure does not end the boot sequence
* Moved Linksys-specific actions into common `/etc/init.d/bootcount`
For upgrade, these devices need to determine which partition to flash,
as well as set certain U-Boot envirnment variables to change the next
boot to the newly flashed version.
* Moved upgrade-related environment changes out of bootcount
* Combined multiple flashes of environment into single one
* Current-partition detection now handles absence of `boot_part`

[checkpatch.pl fixes, traded split strings for 80+ chars per line]
This adds an option to set the recovery flag of newer TP-Link MediaTek
boards and remove it after a successful write.
To make use of this feature, add the '-t' option to mtd-write.
The '-t' option takes the mtd partition containing the recovery flag
(usually 'romfile') as an argument. Make sure this partition is not
flagged as read-only!
Example:
> mtd -t romfile write owrt.bin firmware
This command writes the recovery-flag before it begins writing the image
to the firmware partition. After the image-write has been successful,
the recovery flag is removed.
This way, the TP-Link web-recovery is automatically enabled on an
unsucessful flash (e.g. power loss).
This option is only available if the mtd package is compiled for the
ramips target.

First of all lengths should be compared after checking all blocks for

Reading MTD data with (p)read doesn't return any error when accessing
bad block. As the result, with current code, CRC32 covers "data" stored
in bad blocks.
That behavior doesn't match CFE's one (bootloader simply skips bad
blocks) and may result in:
1) Invalid CRC32
2) CFE refusing to boot firmware with a following error:
Boot program checksum is invalid
Fix that problem by checking every block before reading its content.

So far fixtrx was calculating checksum over amount of data matching
partition erase size. It was mostly a workaround of checksum problem
after changing anything in initial TRX content (e.g. formatting JFFS2).
Its main purpose was to make bootloader accept modified TRX. This didn't
provide much protection of flash data against corruption.
This new option lets caller request calculating checksum over a bigger
amount of data. It may be used e.g. to include whole kernel data for
checksum and hopefully make bootloader go info failsafe mode if
something goes wrong.
