New template defined to represent each family of controllers (identified by processor used). 5861341c939SSumant Patro The template will have defintions that will be initialised to appropritae values for a specific family of controllers. The template definition has four function pointers. During driver initialisation the function pointers will be set based on the controller family type. This change is done to support new controllers that has different processors and thus different register set. 5871341c939SSumant Patro 5881341c939SSumant Patro -Sumant Patro <Sumant.Patro@lsil.com> 5891341c939SSumant Patro 590cb59aa6aSSumant Patro1 Release Date : Mon Dec 19 14:36:26 PST 2005 - Sumant Patro <Sumant.Patro@lsil.com> 591cb59aa6aSSumant Patro2 Current Version : 00.00.02.00-rc4 592cb59aa6aSSumant Patro3 Older Version : 00.00.02.01 593cb59aa6aSSumant Patro 594cb59aa6aSSumant Patroi.
