Implementation Status

[emoose]

TODO:

• [x] update list below with implemented functions
• [ ] add XeKeys functions to list
• [ ] check bootloaders/HV for any other functions that are used outside of XeCrypt-internal stuff
• [ ] add test vectors for each function
• [ ] ensure all _STATE structs are byteswapped before/after accesses to them

Extra: 2/8

These are mentioned in a header file available on pastebin, doesn't seem like kernel has them included though, need to see if any bootloaders or other OS files might include them (otherwise there's not really any way to tell how they're implemented...)

If nothing uses them I guess they aren't that important, but still worth mentioning for completeness sake.
