Subject: [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.

Looks good. One question about the licence.

Can you have a read of the licence rules and add a preferred licence.
The rules are here:

https://www.kernel.org/doc/html/latest/process/license-rules.html

This very hacky one liner will give you an idea of common licences
used by device trees:
