Hi Nate

Thanks for the response.

For the std implementation, I do have some idea how to go about
implementing it now. The most important thing I realized is that most of
the std isn't actually std. For example, std::collection, Vector, Box, Rc,
etc are all actually part of alloc and not std. The things that really are
part of std include threads, i/o, etc.

I have taken a look at some other people's projects who have tried
implementing libstd for other targets and it seems it is possible to write
an implementation without libc. It's just very difficult since in most OS
besides Linux, the syscall ABI is not stable enough and using libc is just
easier and recommended.

As for my earlier patches, Jiewen told me that edkii-rust branch is no
longer maintained and that they are now using a different uefi rust
implementation for their work.

I did also find that it will be possible to make the std with stable Rust
even though if internals use nightly, so that's cool. Some useful projects
about writing libstd for new platform that I found are below:
- https://github.com/betrusted-io/rust/tree/1.54.0.5
- https://github.com/japaric/steed
