[Bug 1870981] [NEW] u-boot environment modification does not work raspberry 4 with eoan

[Michael Johnson]

Public bug reported:

Description:    Ubuntu 19.10
Release:        19.10
Package: u-boot-rpi (2019.07+dfsg-1ubuntu3)

On a Raspberry Pi 3 model B, I can interrupt the u-boot process and use
the following two commands to disable the boot delay. I do this as I
have a GPS device attached to the serial port and the NMEA messages will
halt the u-boot boot process.

Commands:
setenv bootdelay -2
saveenv

This saves a u-boot environment file into the /boot filesystem such that
this setting persists across power cycles.

However, with eoan on a Raspberry Pi 4, this environment file is not
written out properly and on subsequent reboots u-boot will say that the
file is corrupt. This will cause u-boot to revert to the built in
defaults which causes the u-boot process to halt.

** Affects: u-boot (Ubuntu)
     Importance: Undecided
         Status: New
