[Bug 1978923] Re: SRU flash-kernel to add support for RISC-V boards

[Alexandre Ghiti]

** Description changed:

  [Impact]
  
  The image for the StarFive VisionFive and the Nezha boards will be
  available in 22.04.1: in order to be able to boot using UEFI, we need
  flash-kernel to install the DTBs to the right location for GRUB to load,
  so we need to add those boards to the flash-kernel database.
  
  [Test Plan]
  
  I tested the version that built here [1] on the VisionFive board, and
  flash-kernel worked correctly:
