The openbmc flash layouts are currently only used by aspeed devicetrees,
but they don't really depend on any aspeed details. It would be possible
to reuse them in Nuvoton BMC devicetrees in the future, for example.

In that sense, I think putting them in a separate "openbmc" directory
would be slightly better.
