** Description changed:

  Impact:
  
  The dtb for the Raspberry CM3 board is not shipped in the Bionic -raspi2
  kernel arm64 variant.
  
  Fix:
  
- The dtb for the cm3 board was not compiled at all, in the arm64 arch:
- apply the attached patch and recompile
+ The dtb for the cm3 board was not compiled at all, in the arm64 arch -
+ apply the attached patch and recompile.
  
  How to test:
  
  The linux-modules-*-raspi2_arm64.deb should contain the bcm2710-rpi-cm3
  dtb now:
  
  $ dpkg -x linux-modules-4.15.0-1031-raspi2_4.15.0-1031.33_arm64.deb foobar
  ...
  $ ls -l foobar/lib/firmware/4.15.0-1031-raspi2/device-tree/broadcom/
  total 92

  -rw-r--r-- 1 ppisati ppisati 24303 Jan 23 12:59 bcm2710-rpi-3-b.dtb

  -rw-r--r-- 1 ppisati ppisati 17451 Jan 23 12:59 bcm2837-rpi-3-b.dtb
  
  Regression potential:
  
  The patch is trivial - it just builds the cm3 dtb if arch==arm64, and
- doesn't modify any existing code, so there's no regression potential at
- all.
+ doesn't modify any code, so the regression potential is zero.
