Masahiro Yamada b08c8c4870 libfdt: move headers to <linux/libfdt.h> and <linux/libfdt_env.h> 
Thomas reported U-Boot failed to build host tools if libfdt-devel
package is installed because tools include libfdt headers from
/usr/include/ instead of using internal ones.

This commit moves the header code:
  include/libfdt.h         -> include/linux/libfdt.h
  include/libfdt_env.h     -> include/linux/libfdt_env.h

and replaces include directives:
  #include <libfdt.h>      -> #include <linux/libfdt.h>
  #include <libfdt_env.h>  -> #include <linux/libfdt_env.h>

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

The LS2081A Reference Design (RDB) is a high-performance computing,
evaluation, and development platform that supports the QorIQ LS2081A
Layerscape Architecture processor.More details in below sections

LS2080A, LS2088A, LS2081A SoC Overview
--------------------------------------
Please refer arch/arm/cpu/armv8/fsl-layerscape/doc/README.soc for LS2080A,
LS2081A, LS2088A SoC overview.

 LS2081ARDB board Overview
 -------------------------
 LS2081ARDB board is similar to LS2080ARDB board
 with few differences like
  - Hosts LS2081A SoC
  - Default boot source is QSPI-boot
  - Does not have IFC interface
  - RTC and QSPI flash devices are different
  - Provides QIXIS access via I2C

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_2000_0000 .. 0x00_2FFF_FFFF	QSPI region #1
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
---------------

cfg_rcw_src switches needs to be changed for booting from different option.
Refer to board documentation for correct switch setting.

QSPI boot details
===================
Supported only for
 LS2088ARDB RevF board with LS2088A SoC.

Images needs to be copied to QSPI flash
as per memory map given below.

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'
