User-Level ISA document, available from
https://riscv.org/specifications/
+ Due to revisions of the ISA specification, some deviations
+ have arisen over time.
+ Notably, riscv,isa was defined prior to the creation of the
+ Zicsr and Zifencei extensions and thus "i" implies
+ "zicsr_zifencei".
+
While the isa strings in ISA specification are case
insensitive, letters in the riscv,isa string must be all
lowercase to simplify parsing.
