From 36785d7b59726beca320a0b99cfa0a903782c6f3 Mon Sep 17 00:00:00 2001 From: Mark Cave-Ayland Date: Sun, 17 Apr 2016 14:41:50 +0000 Subject: escc.c: add empty ranges property to escc and escc-legacy nodes This fixes an intermittent panic in the AppleSCCSerial module for MacOS 10.2 and the g3beige machine during initialisation as the module tries to write to the on-chip registers at 0x130XX rather than calculating the correct address derived from the parent PCI node. As described in the IEEE-1275 specification: if a "ranges" property exists but has a zero-length property value, the child address space is identical to the parent address space.
