[PATCH] remove PCI dependence from libata

[Jeff Garzik <jgarzik@pobox.com>]

[-- Attachment #1: Type: text/plain, Size: 94 bytes --]


Here's what I just checked in, to libata-2.6, libata-2.4, and 
libata-upstream-2.4 queues.



[-- Attachment #2: patch --]

#
# ChangeSet
#   2004/11/12 19:01:32-05:00 jgarzik@pobox.com 
#   [libata] remove dependence on PCI
#   
#   Most of this work was done by "Mat Loikkanen" <Mat.Loikkanen@synopsys.com>.
#   
#   * use struct device rather than struct pci_dev
#   * use generic DMA routines (dma_xxx) and generic struct device
#     routines (dev_xxx)
#   * isolate PCI-specific helpers inside CONFIG_PCI
