[PATCH v3] ARM: dts: aspeed: Adding Facebook TiogaPass BMC

[Vijay Khemka]

    Initial introduction of Facebook TiogaPass family equipped with
    Aspeed 2500 BMC SoC. TiogaPass is a x86 server development kit
    with a ASPEED ast2500 BMC manufactured by Facebook.
    Specifically, This adds the tiogapass platform device tree file
    including the flash layout used by the tiogapass BMC machines.
    
    This also adds an entry of tiogapass device tree file in Makefile
