128-MB NOR flash layout for QDS and RDB boards
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.
Booting from NAND
-------------------
Booting from NAND requires two images, RCW and u-boot-with-spl.bin.
The difference between NAND boot RCW image and NOR boot image is the PBI
command sequence. Below is one example for PBI commands for QDS which uses
NAND device with 2KB/page, block size 128KB.
1) CCSR 4-byte write to 0x00e00404, data=0x00000000
2) CCSR 4-byte write to 0x00e00400, data=0x1800a000
The above two commands set bootloc register to 0x00000000_1800a000 where
the u-boot code will be running in OCRAM.
3) Block Copy: SRC=0x0107, SRC_ADDR=0x00020000, DEST_ADDR=0x1800a000,
BLOCK_SIZE=0x00014000
This command copies u-boot image from NAND device into OCRAM. The values need
to adjust accordingly.
SRC should match the cfg_rcw_src, the reset config pins. It depends
on the NAND device. See reference manual for cfg_rcw_src.
SRC_ADDR is the offset of u-boot-with-spl.bin image in NAND device. In
the example above, 128KB. For easy maintenance, we put it at
the beginning of next block from RCW.
DEST_ADDR is fixed at 0x1800a000, matching bootloc set above.
BLOCK_SIZE is the size to be copied by PBI.
RCW image should be written to the beginning of NAND device. Example of using
u-boot command
nand write <rcw image in memory> 0 <size of rcw image>
To form the NAND image, build u-boot with NAND config, for example,
ls2085aqds_nand_defconfig. The image needed is u-boot-with-spl.bin.
The u-boot image should be written to match SRC_ADDR, in above example 0x20000.
nand write <u-boot image in memory> 200000 <size of u-boot image>
With these two images in NAND device, the board can boot from NAND.
Another example for RDB boards,
1) CCSR 4-byte write to 0x00e00404, data=0x00000000
2) CCSR 4-byte write to 0x00e00400, data=0x1800a000
3) Block Copy: SRC=0x0119, SRC_ADDR=0x00080000, DEST_ADDR=0x1800a000,
BLOCK_SIZE=0x00014000
nand write <rcw image in memory> 0 <size of rcw image>
nand write <u-boot image in memory> 80000 <size of u-boot image>
Notice the difference from QDS is SRC, SRC_ADDR and the offset of u-boot image
to match board NAND device with 4KB/page, block size 512KB.

Overview
--------
The LS2085A Reference Design (RDB) is a high-performance computing,
evaluation, and development platform that supports the QorIQ LS2085A
Layerscape Architecture processor.
LS2085A SoC Overview
------------------
The LS2085A integrated multicore processor combines eight ARM Cortex-A57
processor cores with high-performance data path acceleration logic and network
and peripheral bus interfaces required for networking, telecom/datacom,
wireless infrastructure, and mil/aerospace applications.
The LS2085A SoC includes the following function and features:
- Eight 64-bit ARM Cortex-A57 CPUs
- 1 MB platform cache with ECC
- Two 64-bit DDR4 SDRAM memory controllers with ECC and interleaving support
- One secondary 32-bit DDR4 SDRAM memory controller, intended for use by

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

* exposed. The following macro is used within the driver for converting *any*
* descriptor pointer to a usable array pointer. The use of a macro (instead of
* an inline) is necessary to work with different descriptor types and to work
