According to the schematics, the only difference is the presence of four DRAM chips ("4D") instead of two. The rest LGTM. Gr{oetje,eeting}s, Geert

Hi Geert,
> Ebisu-4D has a different part number: RTP0RC77990SEB0020S.
Oh, then the elinux wiki entry is at least vague [1]. I checked against
it and it says "This is the Wiki for the Renesas Ebisu (Ebisu-4D,
RTP0RC77990SEB0010S) board," which I read that the the 4D is 10S.
But I'll fix according to your information.
Thanks!

Document properly that Ebisu-support includes the Ebisu-4D variant, so there won't be confusion what happened with support for this board.
