Module Name:
	HalPwrSeqCmd.c

Abstract:
	Implement HW Power sequence configuration CMD handling routine for Realtek devices.

Major Change History:
	When       Who               What
	---------- ---------------   -------------------------------
	2011-10-26 Lucas            Modify to be compatible with SD4-CE driver.
	2011-07-07 Roger            Create.
