The NFP normally requires the source operands to be difference addressing modes, but we should rule out the very special NN_REG_NONE type. There are instruction that ignores both A/B operands, for example: local_csr_rd For these instructions, we might pass the same operand type, NN_REG_NONE, for both A/B operands. NOTE: in current NFP ISA, it is only possible for instructions with unrestricted operands to take none operands, but in case there is new and similar instructoin in restricted form, they would follow similar rules, so swreg_to_restricted is updated as well.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
