Tomáš Macholda ea6ee93060 mvebu: add support for Turris MOX
Adds support for Turris MOX, a modular router extendable by board modules (MOX B-G).

You can explore the idea behind the modules at: https://mox-configurator.turris.cz/

More information about Turris MOX can be found here: https://docs.turris.cz/hw/mox/intro/

Also works with Turris Shield (Turris MOX A and C with a simplified OS UI).

Specifications:
-----------------------

MOX A
- SoC: Marvell Armada 3720
- RAM: 512/1024 MB, DDR3
- Memory:
    - 8 MB SPI NOR Flash for U-Boot and rescue system
    - SD card slot
- 1x RJ-45, 1Gbps
- 1x USB 3.0
- 1x activity LED
- 1x reset button
- SDIO header
- misc pin header (UART, GPIO, JTAG, ...)

MOX B, G
- 1x mPCIe slot
- 1x SIM slot

MOX C
- 4x RJ-45, 1Gbps

MOX D
- SFP, 2.5Gbps

MOX E
- 8x RJ-45, 1Gbps

MOX F
- 4x USB 3.0

Module support:
-----------------------

Additional packages are needed for some modules.

MOX A (core)
- works as is

MOX B, G (mPCIe, mPCIe passthrough)
- works as is

MOX C, E (4x, 8x RJ-45)
- kmod-dsa
- kmod-dsa-mv88e6xxx

MOX D (SFP)
- kmod-sfp
- kmod-phy-marvell-10g

MOX F (4x USB 3.0)
- works as is

Wi-Fi 5, 3x3 card (WLE900VX)
- kmod-ath10k
- ath10k-board-qca988x
- ath10k-firmware-qca988x

Wi-Fi 6, DBDC, 2x2 card (MT7915DAN)
- kmod-mt7915e
- kmod-mt7915-firmware

Interface naming:
-----------------------

- MOX A's RJ-45 is assigned to `eth0`.
- MOX C, E (4x, 8x RJ-45) are assigned to `lan<number>@eth1`
- If MOX D (SFP) is connected directly to MOX A, the resulting interface
  is `eth1`. If it's connected through MOX E (8x RJ-45), the resulting
  interface is `sfp@eth1`.

Quirks:
-----------------------

- MOX is sensitive to the order of connected modules. Verify that the
  confguration is valid at: https://mox-configurator.turris.cz/
- `CONFIG_MOXTET` and `CONFIG_GPIO_MOXTET` need to be enabled in kernel
  config. Moxtet is a bus protocol needed to discover and configure MOX
  modules. It must be compiled into the kernel for the modules to work.
  Though it's very small so it won't bloat up the kernel image.

Flashing instructions:
-----------------------

1. Download `openwrt-*-ext4-sdcard.img.gz` and `gunzip` it.
2. Insert an SD card and flash the image to it using dd:
   dd if=openwrt-*-ext4-sdcard.img.gz of=/dev/mmcblk0 bs=4096 conv=fsync
3. Plug the SD card into MOX.

OpenWrt logo

OpenWrt Project is a Linux operating system targeting embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. For developers, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned.

Sunshine!

Download

Built firmware images are available for many architectures and come with a package selection to be used as WiFi home router. To quickly find a factory image usable to migrate from a vendor stock firmware to OpenWrt, try the Firmware Selector.

If your device is supported, please follow the Info link to see install instructions or consult the support resources listed below.

An advanced user may require additional or specific package. (Toolchain, SDK, ...) For everything else than simple firmware download, try the wiki download page:

Development

To build your own firmware you need a GNU/Linux, BSD or macOS system (case sensitive filesystem required). Cygwin is unsupported because of the lack of a case sensitive file system.

Requirements

You need the following tools to compile OpenWrt, the package names vary between distributions. A complete list with distribution specific packages is found in the Build System Setup documentation.

binutils bzip2 diff find flex gawk gcc-6+ getopt grep install libc-dev libz-dev
make4.1+ perl python3.7+ rsync subversion unzip which

Quickstart

  1. Run ./scripts/feeds update -a to obtain all the latest package definitions defined in feeds.conf / feeds.conf.default

  2. Run ./scripts/feeds install -a to install symlinks for all obtained packages into package/feeds/

  3. Run make menuconfig to select your preferred configuration for the toolchain, target system & firmware packages.

  4. Run make to build your firmware. This will download all sources, build the cross-compile toolchain and then cross-compile the GNU/Linux kernel & all chosen applications for your target system.

The main repository uses multiple sub-repositories to manage packages of different categories. All packages are installed via the OpenWrt package manager called opkg. If you're looking to develop the web interface or port packages to OpenWrt, please find the fitting repository below.

  • LuCI Web Interface: Modern and modular interface to control the device via a web browser.

  • OpenWrt Packages: Community repository of ported packages.

  • OpenWrt Routing: Packages specifically focused on (mesh) routing.

  • OpenWrt Video: Packages specifically focused on display servers and clients (Xorg and Wayland).
