Hi Guenter,

Things have changed. The BeagleBoard.org foundation is no longer
planning to make any further boards using the JH7100 or upcoming
JH7110 SoCs from StarFive. I still think support for the JH7100 will
make it upstream eventually, but I'm no longer confident enough to
recommend merging this before there are more concrete plans for the
SoC. So thanks for the reviews. I'll repost it when I think it's time
to consider it for upstream again.
