[Bug 2036406] Re: [SRU] backport mkeficapsule to jammy

[Aristo Chen]

Hi Heinrich,

Thanks for replying so fast! sorry that I haven't put all the required
info in this bug yet. I am still building the debian package in PPA, but
I would need to put the bug number in changelog, so I open the bug first
without having all info ready

I am planning to backport some patches from higher U-Boot versions for
mkeficapsule, will update the bug once everything is ready, thanks!

Title:
  [SRU] backport mkeficapsule to jammy

Status in u-boot package in Ubuntu:
  New

Bug description:
  Subject: backport mkeficapsule to jammy

  [Impact]

  * mkeficapsule command is used to generate capsule file for updating
  firmware in u-boot

  [Test case]

  Test case 1:
  1. use mkeficapsule command to generate test_new.cap and test_old.cap, both contain U-Boot built at different time 
  2. try to update the capsule file(both test_new.cap and test_old.cap)
  3. check if the U-Boot build stamp is different from previous

  Test case 2:
  1. Follow the command(https://u-boot.readthedocs.io/en/latest/develop/testing.html#pytest-suite) here to test with U-Boot sandbox, and the test_efi_capsule related files were skipped by default before or ater the code changes, the test result can be found in comment

  [Where problems could occur]

  * There is no mkeficapsule command in Jammy yet, so the regression
  risk should be low

  [Other Info]
  N/A
