From cb8250fe4b3c4ed549b270e8a20bc22060e7e1d2 Mon Sep 17 00:00:00 2001 From: Ed Swarthout Date: Fri, 19 Oct 2007 17:51:40 -0500 Subject: [PATCH] fsl_pci_init enable COMMAND_MEMORY if inbound window Patch 16e23c3f removed PCSRBAR allocation. But passing zero windows to pciauto_setup_device has the side effect of not getting COMMAND_MEMORY set.
