Title:
  Not boot with EFI

Status in linux-raspi2 package in Ubuntu:
  Incomplete
Status in linux-raspi2 source package in Bionic:
  In Progress
Status in linux-raspi2 source package in Cosmic:
  In Progress
Status in linux-raspi2 source package in Disco:
  In Progress

Bug description:
  Impact:

  The linux-raspi2 kernel doesn't have the necessary UEFI hooks to boot
  on a UEFI enabled system.

  Fix:

  Enable the relevant UEFI options (see the attached patch).

  How to test:

  On a patched kernel, UEFI presence will be check during boot:

  $ dmesg | grep -i eufi
  ...
  [    0.000000] efi: UEFI not found.
  ...

  Regression potential:

  Very low, some config option changes that have been enabled in generic
  for a long while.

  Hello. I can't boot with linux-raspi2 kernel, but linux-generic work fine. 
Please add support kernel option CONFIG_U(EFI)_STUB=y as default.
  Thanks.

  os: ubuntu 18.04 lts arm64
  hw: raspberry pi 3b (+ tiano core uefi)
