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
| MC DPL Blob |
------------------------- ----> 0x0020_0000
| BootLoader + Env|

| PBI |
------------------------- ----> 0x0000_0080
| RCW |
------------------------- ----> 0x0000_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.
