[PATCH v1 3/3] ARM: dts: aspeed: Add IEISystems NF5280M7 BMC machine

[George Liu]

The IEISystems NF5280M7 is an x86 platform server with an
AST2600-based BMC.
This dts file provides a basic configuration for its OpenBMC
development.

[PATCH v1 3/3] ARM: dts: aspeed: Add IEISystems NF5280M7 BMC machine

[George Liu]

The IEISystems NF5280M7 is an x86 platform server with an
AST2600-based BMC.
This dts file provides a basic configuration for its OpenBMC
development.
