I will follow the proceeding of spec and finish this patch, but I don't think they have been ratified.
There are some changes about RV32E/RV64E <https://github.com/riscv/riscv-isa-manual/pull/860>, but I think they are still **proposal**.
And, there are still some issues we need to fix in the psabi:

- Add the LP64E ABI, to support RV64E <https://github.com/riscv-non-isa/riscv-elf-psabi-doc/pull/299>
- ilp32e issue <https://github.com/riscv-non-isa/riscv-elf-psabi-doc/issues/269>
