This patchset enables the EthernetAVB on the Salvator-X board.
With it and its dependencies in place I have have successfully
booted to an nfsroot user-space (arm64 Debian Jessie).
In order to achieve that I used the following command line set from u-boot.
As per "[PATCH v11 0/8] arm64: renesas: Add Renesas R8A7795 SoC support":
This series has undergone a number of rounds of development and
review on the linux-sh mailing list. This is the first posting to a
wider audience from which we are now seeking review.
It is anticipated that the CPG bindings used this patchset will be
changed before they hit mainline and thus this patchset will need
to be updated accordingly. Reviewers are advised to skip over that
portion of this patchset unless they have a particular interest in
that discussion.

Changes:
* See changelog of individual patches
* Only change since v4 is rebase
Base:
This is based on:
* "[PATCH v11 0/8] arm64: renesas: Add Renesas R8A7795 SoC support"
- topic/arm64-rcar-gen3-v11 branch of my renesas tree
Runtime Dependencies:
* The base (above)
* "[PATCH/RFC v3 net-next 0/4] ravb: Add support for r8a7795 SoC"
and its dependencies

In general all seems good to me, but this I came across the contents of this patch when I was browsing the SoC DTSI file. What is the reason to put this node in between dmac0 and dmac1? I don't know where is the best location, but it would be good to keep the dmac nodes together I think. Cheers, / magnus ^ permalink raw reply [flat|nested] 11+ messages in thread

On slightly closer inspection it seems to be there due to sorting by base address. But it seems rather silly the way it is so I have it in mind to shuffle it down below the dmac nodes. ^ permalink raw reply [flat|nested] 11+ messages in thread
