Two questions:

1. Can we rename the "embedded" directory to the device name? (e.g CV32-something-something-something)
2. Are there plans to incorporate these files into one or more of the index files such as docs/01_cva6_user/index.rst so that it is rendered to HTML by ReadTheDocs?

@MikeOpenHWGroup, based on the Cores TG feedback, we need to know if the this configuration will be single or dual issue before we know the part number: CV32E60X if it is single issue, CV32E6?X (e.g. CV32E62X, CV32E65X) if it is dual issue.

This question can be addressed during Tomorrow meeting. To my mind, this CSR specification is in a file which can be integrated in UM and/or design documentation. This question can be addressed during Tomorrow meeting.

Unfortunately the decision to use Dual issue will be taken when the PPA results will be known, probably January. Until this time, the definitive name will be unknown, that's why I am currently use "embedded" name.
