[PATCH 09/16] ide: remove SATA_*_REG macros

Bartlomiej Zolnierkiewicz
2008-01-21T23:21:50Z

* 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().
