From 8e882ba111bb52fbb42c34a265afb97ddd4fcea1 Mon Sep 17 00:00:00 2001 From: Sergei Shtylyov Date: Mon, 11 Feb 2008 00:32:14 +0100 Subject: [PATCH] ide: introduce CONFIG_BLK_DEV_IDEDMA_SFF option Introduce new option CONFIG_BLK_DEV_IDEDMA_SFF for non-PCI SFF-8038i compatible bus mastering IDE controllers (which there are a few known), thus fixing a hack made for Palmchip BK3710 controller...
