armv8/ls2085aqds: NAND boot support

Browse Source 
This adds NAND boot support for LS2085AQDS, using SPL framework.
Details of forming NAND image can be found in README.

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.
