Bug description:
  [Impact]

  For the upcoming 20.04.2 point release, we want the raspberry pi
  images to have the latest firmware bits available. So this update
  falls under the HWE criterium.

  This bumps the boot firmware to 20210108, the wifi firmware to +rpt10,
  and the bluez firmware to +rpt7.

  The focal backport contains an additional Breaks: flash-kernel
  (<<3.103) entry in d/control as the firmware package changed during
  the groovy cycle to rely on flash-kernel for copying the boot firmware
  to the boot partition rather than using a postinst. Thus the focal
  backport depends on LP: #1904890.

  [Test Case]

  Build a new raspi image for each affected series and do a sanity smoke
  test if it boots, has wifi and bluetooth works.

  Take an existing old raspi image and try to upgrade linux-firmware-
  raspi2, reboot, make sure everything still works.

  [Where problems could occur]

  Basically the only regression-prone parts are wireless, bluetooth and
  possibly bootability. Another place where things could go wrong is
  with package dependencies and the introduced 'Breaks' not doing what
  it should.

  [Original Description]

  Test packages (with backports for groovy and focal) available from the
  following PPA:
