[PATCH] arm: mvebu: support for the PlatHome OpenBlocks AX3 board

[Mio Watanabe]

Dear Jason and all,

Thank you for adding us to the email list.

Thomas is correct. The differences between AX3-2 and AX3-4 are only 3 as following.


                                                    AX3-2                   AX3-4  
No. of ethernet interface                2                           4
SO-DIMM slot                                none                       1                            
mini PCIe slot                                none                       1



I delite Mr. Matumoto from the list since he quit Plat'Home already and
I am his successor. Please just remain "eg@". It is a mailing list
including our development section. Thank you.

Kind regards,
Mio Watanabe
