From 0d5ff566779f894ca9937231a181eb31e4adff0e Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Thu, 1 Feb 2007 15:06:36 +0900 Subject: libata: convert to iomap Convert libata core layer and LLDs to use iomap. * managed iomap is used. Pointer to pcim_iomap_table() is cached at host->iomap and used through out LLDs. This basically replaces host->mmio_base. * if possible, pcim_iomap_regions() is used Most iomap operation conversions are taken from Jeff Garzik 's iomap branch.
