Freescale LayerScape with Chassis Generation 3 is a set of SoCs with ARMv8 cores and 3rd generation of Chassis. We use different MMU setup to support memory map and cache attribute for these SoCs. MMU and cache are enabled very early to bootst performance, especially for early development on emulators. After u-boot relocates to DDR, a new MMU table with QBMan cache access is created in DDR. SMMU pagesize is set in SMMU_sACR register. Both DDR3 and DDR4 are supported.

Signed-off-by: York Sun yorksun@freescale.com Signed-off-by: Varun Sethi Varun.Sethi@freescale.com Signed-off-by: Arnab Basu arnab.basu@freescale.com --- v8: Fix a comment in lowlevel.S v7: Move "dsb sy" and "isb" out of each EL level. Move flusing final MMU table before setting TTBR. v6: Add "dsb sy" before setting TTBR and add "isb" after. v5: Revise the 2nd MMU table code to use the same macros Only change TTBR to point to new MMU table without rewriting MAIR, TCR

v4: Slit ARMv8 MMU change to another patch, v4 2/5 Add more comment for final MMU table setup Remove mmu.h added in v3 and v2 Remove GICv2 macro testing in lowlevel.S Rename function init_type() to initiator_type() Use ARMv8 generic timer code

v3: Remove blank lines at the of files Fix cluster PLL GSR register for accessing beyond array size Update final MMU table to support QBMan memory with cache Set SMMU pagesize in SMMU_sACR register in lowlevel init. Add DDR4 support Remove forcing L3 cache flusing Update GICv3 redistributor base address Some of these changes are caused by model change.

LS2085A is an ARMv8 implementation. This adds board support for emulator and simulator: Two DDR controllers UART2 is used as the console IFC timing is tightened for speedy booting Support DDR3 and DDR4 as separated targets Management Complex (MC) is enabled Support for GIC 500 (based on GICv3 arch)
