Add support for MikroTik RB5009UG

Interesting new home lab router from Mikrotik, the RB5009UG:

Would be nice if we can get OpenWrt support for that device.

Looking forward to this one.

The SoC and switch are maintained in Linux:

The Mikrotik promo video shows board shots which look like there are UART pads (top left) and an SPI-NOR chip (which usually holds the RouterBOOTs, hard & soft configs, and a DTB). The 7.1b6 arm64 firmware has a 70x0*fwf, but device will likely have no-uart set in the hard_config, so no RouterBOOT console without changing that bit on NOR.

Expecting to have to patch Linux to load our DTB from an ELF section, or use an additional bootloader.

I will not be able to get one of these for two months. When someone gets one, a dump of the SPI-NOR chip (mostly for DTB), and a dmesg (or supout) will get us started.

Also interested in. I will order it myself in a month. With a boot loader, I think we'll come up with something. Perhaps I am porting my ipq-aux-loader to it.

I wonder if this processor can do SQM at 1gbps.

RB5009 is just been delivered to me. It looks very cool. Unfortunately, I will have free time to work on it only a month later.

I decided to do some small research on RB5009. After six hours of digging, I managed to jailbreak the RouterOS and get the root console. Here is a ready to use jailbreak:

jailbreak

https://github.com/adron-s/mtik_initrd_hacks/blob/master/ready-kernels/kernel-new-7.1b4-arm64.elf and https://github.com/adron-s/mtik_initrd_hacks/tree/master/for_ftp_upload/pub)

extracted and decompiled DTS.

In total, we have the following:

/dev/mtdblock2  contains:
  Hard config at 0xaf000
  Soft config at 0xc0000
  DTS config at 0xd0000

GPIOs:
  gpio 60 as button
  gpio 91 as all-leds
  gpio 90 as user-led
  gpio 89 as sfp-led
  gpio 87 as usb-power-off

I am planning to get one as it uses fully upstream supported stuff, but they are out of stock eveywhere.

Similar device: https://linuxgizmos.com/marvell-7040-based-networking-sbc-features-10gbe-port-5g-and-wifi-6/

There are plenty of OEM DTS nodes which are not relevant for this device (pcie, spi-poe, which point to future Mikrotik devices using this platform). Given the placeholder macaddr, and the chosen stdout-path in DTS, I would not be surprised if RouterBoot updates these in memory before providing the DTB to linux.

I started to look at mapping the translated OEM DTS phandles to the linux 7040 dtsi, cp0 and ap806 DTS nodes, but expect it to be very wrong at the moment (the phys, ethernet and switch are guesses).

Support for the switch was added in Linux 5.13: de776d0d316f ("net: dsa: mv88e6xxx: add support for mv88e6393x family"), and there have been a few fixups since then.

There is now an example of this switch used in DTS:
https://lore.kernel.org/all/20211018011211.3836590-3-chris.packham@alliedtelesis.co.nz/ with https://github.com/torvalds/linux/blob/master/arch/arm64/boot/dts/marvell/cn9130-crb.dtsi

Would guess this is the switch serdes being configured for 10gbase-r for the CPU and SFP ports, and 2500base-x for the 2.5 WAN ethernet port. The 2.5G WAN ethernet needs a transceiver, and the RouterOS marvell_amethyst.ko includes the string "phy_qca8081_ops". The QCA8081 driver is in the process of being upstreamed now.

I still want one of these, but no ETA at my supplier, and the device using YAFFs complicates things.

I bought my RB5009 here.

I wonder why they needed YAFFS again? They have already begun to use UBI.

Also this device has 16 MB of SPI-NOR:

The only question is, can the RouterBOOT load the kernel from NOR?

I should have some of these soon at work.

Are they seriously using YAFFS again?
They finally moved to UBI on IPQ40xx devices

I'm should also have 1 soon

I will never understand the logic behind YAFFS even, so they wasted their time porting YAFFS to 5.6 kernel

Yes, but the presence of YAFFS adds to us problems when porting OpenWrt to this device. I would like to hope that RouterBoot will be able to boot the kernel from the NOR flash drive ... although this is hard to believe.

Yes, I know since it's not in the upstream kernel.
It brings back the same issues as the ath79 based NAND MikroTik devices.

Alternatively, I will try to implement in kernel2minor writing the kernel to a nand flash drive, taking into account possible bad blocks. At the same time, RB2011 will also benefit from this.
