From 61b9cf7c6cf5077c40ad37480fa56f6574af3db5 Mon Sep 17 00:00:00 2001 From: Mark Maule Date: Fri, 23 Sep 2005 12:31:53 -0500 Subject: [IA64-SGI] fix sn_pci_legacy_read/fix sn_pci_legacy_write This patch adds a #define for SN_SAL_IOIF_PCI_SAFE and makes that the preferred method of implementing sn_pci_legacy_read() and sn_pci_legacy_write(). This SAL call has been present in SGI proms since version 4.10. If the SN_SAL_IOIF_PCI_SAFE call fails, revert to the previous code for compatability with older proms.
