Freescale LayerScape with Chassis Generation 3

This architecture supports Freescale ARMv8 SoCs with Chassis generation 3,
for example LS2085A.

Flash Layout
============

(1) A typical layout of various images (including Linux and other firmware images)
   is shown below considering a 32MB NOR flash device present on most
   pre-silicon platforms (simulator and emulator):

	-------------------------
	| 	FIT Image	|
	| (linux + DTB + RFS)	|
	------------------------- ----> 0x0120_0000
	| 	Debug Server FW |
	------------------------- ----> 0x00C0_0000
	|	AIOP FW 	|
	------------------------- ----> 0x0070_0000
	|	MC FW 		|
	------------------------- ----> 0x006C_0000

Environment Variables
=====================
mcboottimeout:	MC boot timeout in milliseconds. If this variable is not defined
		the value CONFIG_SYS_LS_MC_BOOT_TIMEOUT_MS will be assumed.

mcmemsize:	MC DRAM block size. If this variable is not defined, the value
		CONFIG_SYS_LS_MC_DRAM_BLOCK_MIN_SIZE will be assumed.
