The `0xe100` and `0xe200` are "draft" values - the values in final spec are `0x244` and `0x411`. Here is the PR with related changes https://github.com/ARM-software/abi-aa/pull/227. Sorry for not being clear enough.

I've changed the values in this PR to "draft" ones in order not to mix changes. I'll submit an NFC patch changing them to "production" ones when this is merged.
