I've successfully tested eMMC  on the V3H Starter Kit board. R8A77970 SoC
has a single SDHI core anyway, so can't be  a subject to the known RX DMA
errata...

Nit: some strange double spaces and '...' in the commit message:

Reviewed-by: Wolfram Sang <wsa+renesas@sang-engineering.com>

And out of interest: was this an HS400 eMMC memory?

Thanks!

   Why are you so hostile to ...? :-)

   I ndon';t have the datasheet handy but I don't think it matters -- the board
only supplies 3.3V on both chip's voltage inputs...

To me, it has a meaning: either something is to be continued or the
sentence is intentionaly left open end, so the reader needs to complete
it. I see neither fit here and I don't see any extra value over '.'

Congrats, you got me bike-shedding.

Okay. Pity, would have liked another test report for HS400.

   Should I repost? Or you'd squash the fouble spaces and ellipsis while applying?

   BTW, will this patch go into the next or fixes branch? (I remember Ulf wanted to
stick the analogous R8A77980 patch into fixes.)

I'll leave all these questions to Ulf.

   Sorry, I forgot you don't have a separate repo.

No need to repost, I have amended the change.

Don't recall, but decided to queue this for v4.20. Please tell if you
want me to do otherwise.

Kind regards
