Detailed Description

Keeps track of the relevant data for the physical drive and manages communication with hardware memory module, with it's vector table that point to correct function for particular physical drive implementation. It's intended usage is, as a base structure of a derived structures, eg. sdspi_logical_drive_t. It is not intended to be used independently.
