Explanations
- Device Code Name: product code name, from early prototype phases to production run device. Most commonly used internal reference.
- SoC Family Code Name: device family code name, seems to follow large generational changes in SoC. Mostly seen around hardware (init) code, eg. flash interface, diags, etc.
