@Béla,
+1 for OrangePi (RiscV and ARM both!)
I purchased a couple of the OrangePi RiscV boards but haven't had the time to really get my hands dirty with them yet as much as I would like. (I did design/build an mITX adapter and case and have tested 6x SATA SSD drives with MDADM but other projects tore me away before much else was accomplished.)

I bought this one:

They are audio IC experts, and I suppose this is first "general industrial use" -SOC. Phone codecs are very real time performance critical applications, so they know how to handle linux real time problems.
I think RISC-V MMU is unnecessary complicated, but simplifications need support from linux kernel and RISC-V development groups. I think kernel development and RISC-V groups like tc professional minimalistic approach and efficient code, so I suppose, that support is possible if tc-port is considered...
...and with MMU-development linux problematic device driver mechanism updates automatically, too.

I received yesterday VLSI Solutions RISC-V32 CAT Board (VSRVE01). Very fast delivery, it ready for tc port right now.
At first glance this stuff is very pro, it is targeted for mobile phone android coders, and documentation is very minimal and good. I suppose, linux kernel is installed in "raw format" and single core.
There is another operating system on board for codec, but I think linux side can be operated stand alone.
There is discussion forum:
https://www.vsdsp-forum.com/phpbb/index.php
..and product pages
https://www.vlsi.fi/en/products/vsrves01.html
Unfortunatelly there might be some privilegies set for these pages.
I can recommend this board for tc port, is is very minimalistic and very professionally documented.

Kernel ver. 6.12 has some very interesting RT-features:
https://kernelnewbies.org/Linux_6.12
Interrupt handlers are in kernel thread etc.:

That VLSI Solutions board uses currently 6.1, but natural goal is 6,12 with RT.
