Flash instruction:
The U-boot is based on Ralink SDK so we can flash the firmware using UART:
1. Configure PC with a static IP address and setup an TFTP server.
2. Put the firmware into the tftp directory.
3. Connect the UART line as described on the PCB.
4. Power up the device and press 2, follow the instruction to
   set device and tftp server IP address and input the firmware
   file name. U-boot will then load the firmware and write it into
   the flash.

 - Installation via EVA bootloader
 - OpenWRT sysupgrade
 - Buttons
 - Most LEDs

Not working:
 - 2 RSSI LEDs
   AVM used for RSSI{0,1} two of the Ethernet PHYs LEDs which they
   control over MDIO. Our driver doesn't expose these LEDs as GPIOs.
   While it is possible to implement this feature, it would require an
   additional kernel patch for a minor functionality.

Installation via EVA:
In the first seconds after Power is connected, the bootloader will
listen for FTP connections on 192.168.178.1. Firmware can be uploaded
like following:

  ftp> quote USER adam2
  ftp> quote PASS adam2
  ftp> binary
  ftp> debug
  ftp> passive
  ftp> quote MEDIA FLSH
  ftp> put openwrt-sysupgrade.bin mtd1

Note that this procedure might take up to two minutes.
You need to powercycle the Device afterwards to boot OpenWRT.

Install via TFTP:

Connect to the devices serial. Hit Enter-Key in bootloader to stop
autobooting. Command `tftpboot` will pull an initramfs image named
`C0A86302.img` from a tftp server at `192.168.99.08/24`.
After successfull transfer, boot the image with `bootm`.

To persistently write the firmware, flash an openwrt sysupgrade image
from inside the initramfs, for example transfer
via `scp <sysupgrade> root@192.168.1.1:/tmp` and flash on the device
with `sysupgrade -n /tmp/<sysupgrade>`.

Tested and working:
 - Ethernet

 - 5 GHz WiFi
 - TFTP boot from ramdisk image
 - Installation via ramdisk image
 - OpenWRT sysupgrade
 - Buttons
 - LEDs

Installation seems to be possible only through booting an OpenWRT
ramdisk image.

Hold down the reset button while powering on the device. It will load a
ramdisk image named 'koala-uImage-initramfs-lzma.bin' from 192.168.100.8.

Note: depending on the present software, the device might also try to
pull a file called 'koala-uimage-factory'. Only the name differs, it
is still used as a ramdisk image.

Wait for the ramdisk image to boot. OpenWRT can be written to the flash
via sysupgrade or mtd.

Due to the flip-flop bootloader which we not (yet) support, you need to
set the partition the bootloader is selecting. It is possible from the
initramfs image with

 > fw_setenv bootcmd run bootcmd_1

Afterwards you can reboot the device.

This commit adds support for the Mikrotik RouterBOARD RBM33g.

=Hardware=

The RBM33g is a mt7621 based device featuring three gigabit ports, 2
miniPCIe slots with sim card sockets, 1 M.2 slot, 1 USB 3.0 port and a male
onboard RS-232 serial port. Additionally there are a lot of accessible
GPIO ports and additional buses like i2c, mdio, spi and uart.

==Switch==

The three Ethernet ports are all connected to the internal switch of the
mt7621 SoC:

port 0: Ethernet Port next to barrel jack with PoE printed on it
port 1: Innermost Ethernet Port on opposite side of RS-232 port
port 2: Outermost Ethernet Port on opposite side of RS-232 port
port 6: CPU

==Flash==

The device has two spi flash chips. The first flash chips is rather small
(512 kB), connected to CS0 by default and contains only the RouterBOOT
bootloader and some factory information (e.g. mac address).
The second chip has a size of 16 MB, is by default connected to CS1 and
contains the firmware image.

==PCIe==

The board features three PCIe-enabled slots. Two of them are miniPCIe
slots (PCIe0, PCIe1) and one is a M.2 (Key M) slot (PCIe2).
Each of the miniPCIe slots is connected to a dedicated mini SIM socket
on the back of the board.

Power to all three PCIe-enabled slots is controlled via GPIOs on the
mt7621 SoC:

PCIe0: GPIO9
PCIe1: GPIO10
PCIe2: GPIO11

==USB==

The board has one external USB 3.0 port at the rear. Additionally PCIe
port 0 has a permanently enabled USB interface. PCIe slot 1 shares its
USB interface with the rear USB port. Thus only either the rear USB port
or the USB interface of PCIe slot 1 can be active at the same time. The
jumper next to the rear USB port controls which one is active:

open: USB on PCIe 1 is active
closed: USB on rear USB port is active

==Power==

The board can accept both, passive PoE and external power via a 2.1 mm
barrel jack. The input voltage range is 11-32 V.

=Installation=

==Prerequisites==

A USB -> RS-232 Adapter and a null modem cable are required for
installation.

To install an OpenWRT image to the device two components must be built:

1. A openwrt initramfs image
2. A openwrt sysupgrade image

===initramfs & sysupgrade image===

Select target devices "Mikrotik RBM33G" in
openwrt menuconfig and build the images. This will create the images
"openwrt-ramips-mt7621-mikrotik_rbm33g-initramfs-kernel.bin" and
"openwrt-ramips-mt7621-mikrotik_rbm33g-squashfs-sysupgrade.bin" in the output
directory.

==Installing==

**Make sure to back up your RouterOS license in case you do ever want to
go back to RouterOS using "/system license output" and back up the created
license file.**

Serial settings: 115200 8N1

The installation is a two-step process. First the
"openwrt-ramips-mt7621-mikrotik_rbm33g-initramfs-kernel.bin" must be booted
via tftp:

1. Set up a dhcp server that points the bootfile to tftp server serving
   the "openwrt-ramips-mt7621-mikrotik_rbm33g-initramfs-kernel.bin"
   initramfs image
2. Connect to WAN port (left side, next to sys-LED and power indicator)
3. Connect to serial port of board
4. Power on board and enter RouterBOOT setup menu
5. Set boot device to "boot over ethernet"
6. Set boot protocol to "dhcp protocol" (can be omitted if DHCP server
   allows dynamic bootp)
6. Save config
7. Wait for board to boot via Ethernet

On the serial port you should now be presented with the OpenWRT boot log.
The next steps will install OpenWRT persistently.

1. Copy "openwrt-ramips-mt7621-mikrotik_rbm33g-squashfs-sysupgrade.bin" to the device
   using scp.
2. Write openwrt to flash using "sysupgrade
   openwrt-ramips-mt7621-mikrotik_rbm33g-squashfs-sysupgrade.bin"

Once the flashing completes reboot the router and let it boot from flash.
It should boot straight to OpenWRT.
