[PATCH 1/1] ARM:dts:aspeed: Initial device tree for AMD EthanolX
Initial introduction of AMD EthanolX platform equipped with an Aspeed ast2500 BMC manufactured by AMD. AMD EthanolX platform is an AMD customer reference board with an Aspeed ast2500 BMC manufactured by AMD. This adds AMD EthanolX device tree file including the flash layout used by EthanolX BMC machines. This also adds an entry of AMD EthanolX device tree file in Makefile.
