From 24f073d4009e4a35091c676aff83c03dac5c1a6b Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 16 Dec 2021 20:59:37 -0700 Subject: fdt: Makefile: Ensure that OF_BOARD is used when needed Boards which define OF_HAS_PRIOR_STAGE must define OF_BOARD at present, since a custom function is the only way to obtain the devicetree at runtime. Add a build error when this requirement is not met, to avoid accepting any patches which break this requirement. Add an allowlist for boards which use it, currently none. This allowlist can be updated for local development, if needed.
