hostboot-feature-attributes.md

Below is a list of feature attributes from src/import/chips/p9/procedures/xml/attribute_info/chip_ec_attributes.xml in Hostboot which are not identical across DD2.*.

Grouping is rather approximate as descriptions are non-existent or short and cryptic. With some effort grouping can probably be improved a bit.

Most of the attributes are not mentioned in the code, those which appear in code or init-files are marked in the corresponding column.
