+ Summary:
+ Add preliminary support for Windtunnel PowerMacs to ofpath
+ Revision:
+ yaboot--devel--1.3--patch-34
+
+ * CHANGES IN THIS COMMIT ARE PRELIMINARY **DO NOT DISTRIBUTE**
+
+ * ofpath: Add preliminary support for Windtunnel PowerMacs
+ - If /proc/ide/pmac (perhaps to be renamed) does not exist and
+ machine is a Windtunnel return ultra2: instead of hd: (this assumes
+ machines without /proc/ide/pmac are also without support for ATA-100,
+ ultra2: is the ATA-66 bus).
+ - Parse a modified version of /proc/ide/pmac to determine the
+ appropriate OpenFirmware device specifier, no kernel yet has the
+ correct version of this file.
+
+ modified files:
+ ChangeLog Makefile ybin/ofpath ybin/ybin
