Overview
--------
The LS2080A Reference Design (RDB) is a high-performance computing,
evaluation, and development platform that supports the QorIQ LS2080A, LS2088A
Layerscape Architecture processor.

LS2080A, LS2088A SoC Overview
--------------------
Please refer arch/arm/cpu/armv8/fsl-layerscape/doc/README.soc for LS2080A,
LS2088A SoC overview.

 LS2080ARDB board Overview
 -----------------------
 - SERDES Connections, 16 lanes supporting:
      - PCI Express - 3.0

Memory map from core's view
----------------------------
0x00_0000_0000 .. 0x00_000F_FFFF	Boot Rom
0x00_0100_0000 .. 0x00_0FFF_FFFF	CCSR
0x00_1800_0000 .. 0x00_181F_FFFF	OCRAM
0x00_3000_0000 .. 0x00_3FFF_FFFF	IFC region #1
0x00_8000_0000 .. 0x00_FFFF_FFFF	DDR region #1
0x05_1000_0000 .. 0x05_FFFF_FFFF	IFC region #2
0x80_8000_0000 .. 0xFF_FFFF_FFFF	DDR region #2

Other addresses are either reserved, or not used directly by U-Boot.
This list should be updated when more addresses are used.

IFC region map from core's view
-------------------------------
During boot i.e. IFC Region #1:-
  0x30000000 - 0x37ffffff : 128MB : NOR flash
  0x3C000000 - 0x40000000 : 64MB  : CPLD

After relocate to DDR i.e. IFC Region #2:-
  0x5_1000_0000..0x5_1fff_ffff	Memory Hole
  0x5_2000_0000..0x5_3fff_ffff	IFC CSx (CPLD, NAND and others 512MB)
  0x5_4000_0000..0x5_7fff_ffff	ASIC or others 1GB
  0x5_8000_0000..0x5_bfff_ffff	IFC CS0 1GB (NOR/Promjet)
  0x5_C000_0000..0x5_ffff_ffff	IFC CS1 1GB (NOR/Promjet)

Booting Options
---------------
a) NOR boot
b) NAND boot

Booting Linux flavors which do not support 48-bit VA (< Linux 3.18)
-------------------------------------------------------------------
One needs to use appropriate bootargs to boot Linux flavors which do
not support 48-bit VA (for e.g. < Linux 3.18) by appending mem=2048M, as shown
below:

=> setenv bootargs 'console=ttyS1,115200 root=/dev/ram
   earlycon=uart8250,mmio,0x21c0600,115200 default_hugepagesz=2m hugepagesz=2m
   hugepages=16 mem=2048M'
