From 190de005384204ba4dc339c3d05f8d40f6b16643 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Fri, 21 Dec 2007 15:39:33 +1100 Subject: [POWERPC] 4xx: Rework clock probing in boot wrapper This reworks the boot wrapper library function that probes the chip clocks. Better separate the base function that is used on 440GX,SPe,EP,... from the uart fixups as those need different device-tree path on different processors. Also, rework the function itself based on the arch/ppc code from Eugene Surovegin which I find more readable, and which handles one more bypass case. Also handle the subtle difference between 440EP/EPx and 440SPe/GX, on the former, PerClk is derived from the PLB clock while on the later, it's derived from the OPB.
