93be5926a2 ramips: mt7621: create DTSI for Xiaomi NAND devices
This creates a DTSI for Xiaomi devices with 128M NAND.

This allows to consolidate the partitions and a few other nodes for
AC2100 family and Mi Router 3G.

Note that the Mi Router 3 Pro has 256M NAND and differently sized
partitions.

1de9cac2f9 ramips: move redundant console setup to mt7621 SoC DTSI
For mt7621, console is set up via DTS bootargs individually in
device DTS/DTSI files. However, 44 of 74 statements use the
following setting:

	chosen {
		bootargs = "console=ttyS0,57600";
	};

Therefore, don't repeat ourselves and move that definition to the SoC
DTSI file to serve as a default value.

This patch is cosmetic.

53a1fede1f ramips: Add support for Xiaomi Mi Router(Black,R2100)
The Xiaomi Mi Router AC2100 is a *black* cylindrical router that shares many
characteristics (apart from its looks and the GPIO ports) with the 6-antenna
*white* "Xiaomi Redmi Router AC2100"

See the visual comparison of the two routers here:
https://github.com/emirefek/openwrt-R2100/raw/imgcdn/rm2100-r2100.jpg

Specification of R2100:
- CPU: MediaTek MT7621A
- RAM: 128 MB DDR3
- FLASH: 128 MB ESMT NAND
- WIFI: 2x2 802.11bgn (MT7603)
- WIFI: 4x4 802.11ac (MT7615)
- ETH: 3xLAN+1xWAN 1000base-T
- LED: Power, WAN in Yellow and Blue
- UART: On board (Don't know where is should be confirmed by anybody else)
- Modified u-boot

Hacking of official firmware process is same at both RM2100 and R2100.
Thanks to @namidairo

Here is the detailed guide Hack: https://github.com/impulse/ac2100-openwrt-guide
Guide is written for MacOS but it will work at linux.
needed packages: python3(with scapy), netcat, http server, telnet client

1. Run PPPoE&exploit to get nc and wget busybox, get telnet and wget firmware
2. mtd write openwrt-ramips-mt7621-xiaomi_mi-router-ac2100-kernel1.bin kernel1
3. nvram set uart_en=1
4. nvram set bootdelay=5
5. nvram set flag_try_sys1_failed=1
6. nvram commit
7. mtd -r write openwrt-ramips-mt7621-xiaomi_mi-router-ac2100-rootfs0.bin rootfs0

other than these I specified in here. Everything is same with:
f3792690c4
Thanks for all community and especially for this device:
