[Bug 1934791] Re: SRU u-boot to focal to enable HiFive Unmatched booting

[Brian Murray]

Hello William, or anyone else affected,

Accepted u-boot into focal-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/u-boot/2021.01+dfsg-3ubuntu0~20.04.1
in a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
focal to verification-done-focal. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-focal. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

** Changed in: u-boot (Ubuntu Focal)
       Status: New => Fix Committed

** Tags added: verification-needed verification-needed-focal

Title:
  SRU u-boot to focal to enable HiFive Unmatched booting

Status in u-boot package in Ubuntu:
  New
Status in u-boot source package in Focal:
  Fix Committed

Bug description:
  In order to boot Ubuntu 20.04 on the Unmatched, the version of u-boot
  currently in hirsute will need to be SRU'd to focal.

  Raspberry pi core and classic images will need to be tested with this
  new version of u-boot as well to ensure nothing was broken by the SRU.

  [Impact]

   * Without the hirsute version of u-boot, the HiFive Unmatched
     will not boot focal

  [Test Case]

  For RISC-V "unmatched" boards:
   * Attempt to boot the Unmatched with current focal image containing u-boot 2020.10+dfsg-1ubuntu0~20.04.2
   * Note that it fails to boot
   * Build image with u-boot from proposed
   * Attempt to boot the Unmatched with the new version of u-boot
   * Verify that u-boot is able to load the kernel

  For Raspberry Pi boards (2, 3, 3+, 4 (inc. 8GB variant), 400, CM4):
   * Flash focal image to an SD card and boot it on the relevant Pi
   * Ensure card is fully up to date (sudo apt update && sudo apt upgrade)
   * Enable proposed (https://wiki.ubuntu.com/Testing/EnableProposed)
   * Update u-boot (sudo apt install u-boot-rpi)
   * Check reboot still boots successfully (sudo reboot)

  [Regression Potential]

  There are multiple changes being SRU'd, but since we know they all
  work in hirsute on these models the risk is fairly low. Attempts to
  boot all the supported Raspberry pi models should still be made to
  ensure no regression.
