The DWR-921-C3 Wireless Routers with LTE embedded modem is based on the
MT7620N SoC.
Specification:
* MediaTek MT7620N (580 Mhz)
* 64 MB of RAM
* 16 MB of FLASH
* 802.11bgn radio
* 5x 10/100 Mbps Ethernet (1 WAN and 4 LAN)

* 1x bi-color Signal Strength LED (GPIO-controlled)
* 2x button
* JBOOT bootloader
Installation:
Apply factory image via d-link http web-gui.
How to revert to OEM firmware:
1.) Push the reset button and turn on the power. Wait until LED start
blinking (~10sec.)
2.) Upload original factory image via JBOOT http (IP: 192.168.123.254)
3.) If http doesn't work, it can be done with curl command:
curl -F FN=@XXXXX.binhttp://192.168.123.254/upg

msdc_6575_host[] is unused, just remove it. Also, it
was the source of memory corruption up until the
previous fix to this driver.
Signed-off-by: André Draszik <git@andred.net>
pdev->id is -1 when only one device exists, and is used:
* as an index into drv_mode[] to determine whether to use
PIO or DMA mode (via host->id)
* as an index into msdc_6575_host[], to store the
mmc_priv() data.
Obviously, -1 is not a valid index in either case, causing
us to read invalid memory, and memory corruption,
respectively.
The invalid memory read is causing non-deterministic
behaviour, in particular in the v4.4 kernel it still
picked DMA mode, but in the v4.9 it now always picks
PIO mode.
Also, PIO mode doesn't work, causing the following:
/ # echo 3 > /proc/sys/vm/drop_caches

Usage: /root/usr/lib/libc.so [options] [--] pathname [args]
(i.e. initial page-in of any binary causes a segfault,
subsequent access works.)
While this change doesn't fix PIO mode, it at least makes
us deterministically use DMA (which works), and it also
stops us from corrupting memory.

TP-Link TL-WR902AC v3 is a pocket-size dual-band (AC750) router
based on MediaTek MT7628N + MT7650E.
Specification:
- MediaTek MT7628N/N (580 Mhz)
- 64 MB of RAM
- 8 MB of FLASH
- 2T2R 2.4 GHz and 1T1R 5 GHz
- 1x 10/100 Mbps Ethernet
* MT7650 ac chip isn't not supported by LEDE/OpenWrt at the moment.
Therefore 5Ghz won' work.
Flash instruction:
The only way to flash LEDE image in TL-WR902AC v3 is to use
tftp recovery mode in U-Boot:
1. Configure PC with static IP 192.168.0.66/24 and tftp server.
2. Rename "openwrt-ramips-mt76x8-tplink_tl-wr902ac-v3-squashfs-tftp-recovery.bin"

3. Connect PC with the LAN port, press the reset button, power up
the router and keep button pressed for around 6-7 seconds, until
device starts downloading the file.
4. Router will download file from server, write it to flash and reboot.

Flash instructions:
The GnuBee Personal Cloud Two ships with libreCMC installed.
libreCMC is a Free Software Foundation approved fork of LEDE/OpenWrt.
As such one can upgrade using the webinterface or sysupgrade.
Das U-Boot has multiple options for recovery or updates including :
- USB
- http
- tftp
Errata:
- While there are three ethernet ports, the third requires support for
the second GMAC. This will come in kernel 4.14.
- The first hard drive slot has a clearance issue with the two fan
headers. Workaround is to pull the headers out and connect the pins to
jumper wires.
- Using this device as a NAS is problematic with the 4.9 kernel as many
/dev/sdX reads throw silent errors. The current theory behind this is
some kind of unhandled DMA mapping error in the kernel. This is not an
issue with kernel 4.4.
