[PATCH linux dev-5.0] ARM: dts: aspeed: Initial git pull request for Microsoft Olympus BMC

[Hongwei Zhang]

Olympus is a Microsoft OCP platform equipped with Aspeed 2400 BMC
SoC.
Tested: meta-olympus has been tested on an ASPEED AST2400 EVB board
        and MT Olympus server.
        The U-boot and kernel start and run as expected.
