Bug description:
  [Impact]

  Version 2019.10 (which is post-focal) includes a fix for LP: #1900693
  which is critical for Core 18, and important for anyone relying on the
  "saveenv" function in u-boot. Version 2020.04 (also post-focal),
  introduced support for the Pi 4 ethernet controller. The intention is
  to SRU the hirsute version (2020.10) to bionic, focal, and groovy.

  [Test Case]

  * On a fresh copy of Ubuntu Bionic, Focal, and Groovy:
  * Enable -proposed and do `apt update`
  * Update u-boot packages
  * sudo reboot
  * Ensure the OS boots successfully

  Additionally:

  * Perform validation as per the bug LP: #1900693.

  [Regression Potential]

  Provided the new version successfully boots on all intended targets,
  minimal since the bootloader plays no role at runtime beyond getting
  the Linux kernel running. However, given this potentially affects many
  platforms (not just the Pi), it should be given a boot test on all
  platforms we support via U-Boot.

  [Original Description]

  Please merge u-boot 2020.10+dfsg-1 from Debian unstable.

  Updated changelog and diff against Debian unstable is attached below.
