[U-Boot] [Patch v9 5/5] ARMv8/ls2085a_emu: Add LS2085A emulator and simulator board support

York Sun yorksun at freescale.com
Tue Jun 24 00:15:56 CEST 2014


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)

Change log
 v9: no change
 v8: Rename ls2100a to ls2085a according to latest SoC name.
     Add "support for GIC 500" in commit message.
 v7: no change
 v6: no change
 v5: no change
 v4: no change
 v3: Add support for DDR4 target and simulator target
     Squash Manage complex patch (previous 5/5) into this
     Reserve last 512MB memory for MC use
     Change MC firmware location in NOR flash
     Fix UART clock source speed
     Update IFC address mux
     Use generic board
     Disable DDR memory beyound 39 physical address space due to Linux limitation
