Alexander Shiyan (Cc'ed) reads the information from an nvmem cell:

The idea is to fixup the device tree in the bootloader depending on the
SoC revision, so that the CAN driver uses only the needed workarounds.

Thanks, it is not easy to correlate this because I am currently not using
barebox. I'll try this later.

The most important information in this code is where the SoC revision is
located: there is a separate nvmem cell for this. You can read out the
information once manually and change your device tree accordingly.

Marc
