marius 62ac140238 - Don't set CAS_PCS_DATAPATH to anything except CAS_PCS_DATAPATH_SERDES ... on Cassini using the external PCS SERDES otherwise unaligned access traps and other strange effects happen with some machines. Don't touch the MIF which is unused in that case either. These changes require the PHY type to use to be determined via the OFW device tree or from the VPD in machines without the former. - Disable the SERDES pins of Saturn when not used in order to save power and ensure they are enabled otherwise. - In cas_attach() use the correct register offset for CAS_PCS_CONF_EN. - Add some bus space barriers missing in the PCS code path. These changes make the Sun GigaSwift Ethernet 1.0 MMF cards as well as the on-board interfaces found in Sun Fire B100s Blade Server work. PR: 144867		2010-05-03 20:57:16 +00:00
