Greetings,
I've been working with a tagging system so that multiple payloads in firmware can be selected from serial at boot time. The scheme adds a 16 byte tag block in front of each payload containing a $TAG$ signature, additional block count, a payload length (optional, may be 0), and a name string. The idea is to search for tags in the ROM, present the name strings in a list and allow selection of a particular target. The stream is then positioned just past the tag and passed to elfboot. changes: elfboot no longer calls stream->init(), it presumes that has been done already. add stream methods: searchtags gettags loadtag search tags performs the search and specifies the neded buffer size to hold the result. gettags loads the tags into a provided buffer for presentation loadtag positions the stream just after the selected tag index (0 based) for backwards compatability: Where no tags are found, the stream is positioned at the beginning where the stream->searchtags == NULL, presume the stream object doesn't support tags. Just call init and pass it to elfboot. Yes, No, Comments?
