From 16e23c3f5dab6937f5109365416808c7f15c122b Mon Sep 17 00:00:00 2001 From: Ed Swarthout Date: Mon, 20 Aug 2007 23:55:33 -0500 Subject: [PATCH] fsl_pci_init - Remove self PCSRBAR allocation CPU physical address space was being wasted by allocating a PCSRBAR PCI inbound region to it's memory space. As a rule, PCSRBAR should be left alone since it does not affect transactions from self and other masters may have changed it.
