From f51cdaf19141151ce2b40d562a468605340f2315 Mon Sep 17 00:00:00 2001 From: Becky Bruce Date: Thu, 17 Jun 2010 11:37:20 -0500 Subject: 83xx/85xx/86xx: LBC register cleanup Currently, 83xx, 86xx, and 85xx have a lot of duplicated code dedicated to defining and manipulating the LBC registers. Merge this into a single spot. To do this, we have to decide on a common name for the data structure that holds the lbc registers - it will now be known as fsl_lbc_t, and we adopt a common name for the immap layouts that include the lbc - this was previously known as either im_lbc or lbus; use the former. In addition, create accessors for the BR/OR regs that use in/out_be32 and use those instead of the mismash of access methods currently in play. I have done a successful ppc build all and tested a board or two from each processor family.
