Guidance on naming conventions

• Spelling should be BeagleV not Beagle-V
  • BeagleV is BeagleBoard.org Foundation's name for RISC-V boards
• The board name is BeagleV Starlight for this board.
  • The board that limited number of developers have thus far received is beta version of the BeagleV Starlight
  • This FAQ describes difference between beta and production.
• Board vendor is BeagleBoard.org Foundation
  • BeagleV Starlight is manufactured by Seeed Studio for BeagleBoard.org Foundation
  • Refer to"^beagle,.*" in vendor-prefixes.yaml
• StarFive SoC: VIC renamed to JH
  • The beta BeagleV Starlight board has StarFive JH7100 SoC
  • StarFive had referred it internally as VIC7100 but the public name is JH7100
  • StarFive has renamed datasheet to JH7100
  • There are still many references to VIC and VIC7100 instead of JH7100 which will be cleaned up
• StarFive JH7100 versus JH7110
  • The beta BeagleV Starlight board has the StarFive JH7100
  • StarFive JH7110 is mass production chip which will be used in future BeagleV Starlight boards
    • JH7110 upgrade from 2x to 4x U74 cores and adds PCIe and GPU
  • Recommendation is to use beagle,beaglev-starlight-jh7100 and beagle,beaglev-starlight-jh7110 to differientate between the board versions
• SiFive cores in the StarFive SoC:
  • StarFive JH7100 SoC has 2x SiFive U74-MC
  • StarFive JH7110 SoC will have 4x SiFive U74-MC
