	#Author: Dave Gerlach <d-gerlach@ti.com>
	#Date:   Tue Sep 6 14:33:11 2016 -0500
	#
	#    CM3: Firmware release 0x192
	#    
	#    This version, 0x192, includes the following changes:
	#         - Fix DDR IO CTRL handling during suspend so both am335x and am437x
	#           use optimal low power state and restore the exact previous
	#           configuration.
	#        - Explicitly configure PER state in standby, even though it is
	#           configured to ON state to ensure proper state.
	#         - Add new 'halt' flag in IPC_REG4 bit 11 to allow HLOS to configure
	#           the suspend path to wait immediately before suspending the system
	#           entirely to allow JTAG visiblity for debug.
	#         - Fix board voltage scaling binaries i2c speed configuration in
	#           order to properly configure 100khz operation.
	#    
	#    Signed-off-by: Dave Gerlach <d-gerlach@ti.com>
