We already have NAND boot explained in other document. Stick with the 
procedure you are trying to explain. Keep it simple and we can expand it 
when necessary.

I'm not be familiar with SD/NAND boot. So should I rename as README.qspi?
Or just keep it but waiting for some others to add SD/NAND boot in another 
patch?

+Booting from QSPI
+---
+Booting from QSPI requires two images, RCW and u-boot-dtb.bin.
+The difference between QSPI boot RCW image and NOR boot image is the PBI
+command sequence for setting the boot location pointer. It's should point
+to the address for u-boot in QSPI flash.
+
+RCW image should be written to the beginning of QSPI flash device.
+Example of using u-boot command
+
+=> sf probe 0:0
+SF: Detected S25FL256S_64K with page size 256 Bytes, erase size 64 KiB, total 
32 MiB
+=> sf erase 0 +
+SF: 65536 bytes @ 0x0 Erased: OK
+=> sf write  0 
+SF: 164 bytes @ 0x0 Written: OK
+
+To get the QSPI image, build u-boot with QSPI config, for example,
+_qspi_defconfig. The image needed is u-boot-dtb.bin.
+The u-boot image should be written to 0x1(but 0x1000 for LS1043A, LS2080A).
+

+=> sf write  1 
+SF: 580966 bytes @ 0x1 Written: OK
+
+With these two images in QSPI flash device, the board can boot from QSPI.

If you plan to add all SD/NAND/QSPI into this document, it is OK to call 
it README.deploy. Otherwise it may be better to name as README.qspi.
