Date: Thu, 30 Aug 2018 14:05:22 -0500 From: Rob Herring <robh@...nel.org> To: Frank Rowand <frowand.list@...il.com>, devicetree@...r.kernel.org Cc: linux-kernel@...r.kernel.org Subject: [PATCH 2/3] of/fdt: avoid re-parsing '#{address,size}-cells' in of_fdt_limit_memory Now that we initialize dt_root_addr_cells and dt_root_size_cells earlier, use them and simplify of_fdt_limit_memory.
