[PATCH 0/4] ARM: dts: aspeed: add dtsi for Facebook AST2500 Network BMCs

[Tao Ren]

The patch series adds "facebook-netbmc-ast2500-common.dtsi" which defines
devices that are common cross all Facebook AST2500 Network BMC platforms.
The major purpose is to minimize duplicated device entries among Facebook
Network BMC dts files.

Patch #1 (of 4) adds "facebook-netbmc-ast2500-common.dtsi" file, and the
remaining 3 patches update CMM, Minipack and Yamp device tree to consume
the new dtsi file.

Was this included to work around the IPv6 issue that Benh recently fixed?

If you can test your platform with
88824e3bf29a2fcacfd9ebbfe03063649f0f3254 applied and the
no-hw-checksum property removed, please send a follow up to remove
this property.

It's not doing any harm, but by cleaning it up there's less chance
others blindly copy the same thing.

Thanks,

Joel

Yes. I'm planning to try the patch. Will send out a followup patch to
remove the line if everything goes fine.

[PATCH 2/4] ARM: dts: aspeed: cmm: include dtsi for common network BMC devices

[Tao Ren]

The patch simplifies CMM device tree by including dtsi to define devices
which are common to Facebook AST2500 Network BMC platforms.

Below is the summary of changes comparing with previous dts version:
  - enabling the second firmware flash.
  - enabling the emmc device in slot #0.

[PATCH 3/4] ARM: dts: aspeed: minipack: include dtsi for common network BMC devices

[Tao Ren]

The patch simplifies Minipack device tree by including dtsi to define
devices which are common to Facebook AST2500 Network BMC platforms.

Below is the summary of changes comparing with previous dts version:
  - enabling the second firmware flash.
  - updating firmware flashes' size from 32MB to 64MB.
  - enabling the emmc device in slot #1.

The patches look okay to me. I modified the file name to match the
convention used by other device trees in the arm directory, where it
includes the SOC name first.

I also reworded the commit messages a little.

They have been merged into the aspeed tree for submission to 5.5.

Thanks!
