[RFC V1 4/4] SCSI: UFS: Added support of PCI/PLTFM for UFS

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


This patch modifies the Kconfig and the Makefile to
add support for PCI and Platform config options to the
UFS core driver. If the device is attached to the core
throught pci,then PCI option has to be selected in the
menuconfig. For more information read the help section
of Kconfig file.
