# Modification History
#
# Ver   Who  Date     Changes
# ----- ---- -------- -----------------------------------------------
# 3.03a sdm  08/11/10 Added C_SPI_MODE parameter to config structure
# 3.04a bss  03/21/12 Added C_TYPE_OF_AXI4_INTERFACE, C_AXI4_BASEADDR and
#	              C_XIP_MODE to config structure.
# 		      Modified such that based on C_XIP_MODE and 
#		      C_TYPE_OF_AXI4_INTERFACE parameters C_BASEADDR will 
#		      be updated with the value of C_AXI4_BASEADDR.
#		      Modified such that C_FIFO_EXIST will be updated based
#		      on C_FIFO_DEPTH for compatability of driver
# 3.06a adk 07/08/13 Added C_USE_STARTUP parameter to the config structure
# 4.0   adk 12/10/13 Updated as per the New Tcl API's
