From f5903ede0015db5b53458092b6ae2af074fa49d4 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Tue, 5 Feb 2008 23:01:50 +1100 Subject: [PATCH] [POWERPC] Fix legacy serial search for opb bus ports The patch to legacy_serial.c (1a7507c7da2df6856e085e0fbb0c9ea8c12ac4e, Reduce code duplication in legacy_serial, add UART parent types) changed the semantics for opb ports from type = "opb" || compatible = "ibm,opb" to type = "opb" && compatible = "ibm,opb". The result is serial ports on our QS21s (Cell blades) don't get found, and for some reason the machine doesn't boot at all - possibly it's panicking due to lack of a console? The fix is to add two entries to the of_device_id table, one that looks for type = "opb" and the other compatible = "ibm,opb".
