From 835457def90c86fe84d7729c0531fd551fb14eda Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Sat, 2 Feb 2008 19:56:45 +0100 Subject: ide: remove SATA_*_REG macros * siimage.c: use hwif->sata_scr[SATA_{ERROR,STATUS}_OFFSET] instead of SATA_{ERROR,STATUS}_REG macros. * Remove no longer needed SATA_*_REG macros. While at it: * Remove needless SATA Status register read from sil_sata_reset_poll().
