[U-Boot] [v2 PATCH 0/4] Switch odroid to use distro_bootcmd.

[U-Boot] [v2 PATCH 0/4] Switch odroid to use distro_bootcmd.

[Vagrant Cascadian]

Using distro_bootcmd standardizes board behavior across many
platforms. This is particularly useful for distributions supporting
multiple boards without requiring custom configuration for each board.

There are a few changes needed to support distro_bootcmd, such as
fixing the default value for the console setting, increasing the
environment size, and allowing distro bootcmd to set the default
bootdelay.

These patches have been used in Debian's u-boot packaging since May of
2016.


Vagrant Cascadian (4):
  Fix default console on odroid to only specify the device, as
    "console=" is redundant with the boot environment.
  Increase the default environment size on odroid, as
    config_distro_bootcmd requires a more space for the environment.
  Switch odroid to use config_distro_bootcmd.
  Inherit default value for bootdelay from distro_bootcmd on odroid.

[U-Boot] [v2 PATCH 4/4] Inherit default value for bootdelay from distro_bootcmd on odroid.

[Vagrant Cascadian]

The default value with distro_bootcmd is 2 seconds, which is
reasonably fast, and provides a consistent experience across platforms
supporting distro_bootcmd.

The current bootdelay value of 0 seconds is a bit challenging to
interrupt when desired.
