This patch enables the following features: a) Boots and shuts down the card via sysfs entries. b) Allocates and maps a device page for communication with the card driver and updates the device page address via scratchpad registers. c) Provides sysfs entries for shutdown status, kernel command line, ramdisk and log buffer information.
