From 00b7d1cf46676ad5e6338e80dc6230e1b6e71b86 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Wed, 29 Aug 2018 17:21:45 -0500 Subject: [PATCH] of: make default address and size cells sizes private Only some old OpenFirmware implementations rely on default sizes. Any FDT and modern implementation should have explicit properties. Make the OF_ROOT_NODE_*_CELLS_DEFAULT defines private so we don't get any outside users. This also gets us one step closer to removing the asm/prom.h dependency on Sparc. Cc: "David S.
