Do you mean "SPI flash"?

You don't have NAND or SD boot option with this patch yet. They were added
later. So you can update the README when you have those support.

You may want to try to use -M -C when generating the patch, to see if the patch
can be smaller. I have a feeling many files are copy-n-paste with some
modification.
