Documentation/boards/riscv.rst: can't rebuild image for BeagleV

[Antony Pavlov]

Hi Ahmad!

I have tried to rebuild barebox for BeagleV.
Alas I was unable to reproduce the steps from Documentation/boards/riscv.rst
because of changes in opensbi repo.

I have successfully rebuild U-Boot from the https://github.com/andreiw/uboot_jh7100 repo
and used it for running sbi-less BeagleV barebox image.

I planned to use BeagleV for picotcp demonstration but BeagleV ethernet adapter
does not works neither under U-Boot nor under barebox. My dhcp server can't even
receive any request from BeagleV.

Have we any chance to make BeagleV ethernet adapter works under barebox?

I've been meaning to sync barebox with the kernel, now that there's upstream
support for the JH7100. Ethernet on this SoC was a bit peculiar, because
previous RISC-V SoCs were fully cache-coherent, but the MAC on this SoC wasn't.

I got Ethernet to work though, so if it's broken now, it is a regression.

I will try building an image when I have time.

Cheers,
Ahmad

I just Cc'd[1] you on a documentation patch that describes how it needs
to be built now.

Thanks to your report, I found a bug in my DMA coherency patches that made it
into v2024.02.0. I Cc'd[2] you on the fix. Ethernet works again now.
