# If you intend to use 'outside' of 'global' variables from U-Boot, make sure that you do not change them!

# The boot logic will attempt a list of 'boot_targets' that all might rely on (environment) variables that
|
||||
# have been set by U-Boot, either compile-time or as part of U-Boot's default 'bootcmd'.
|

# Any variable that this bootscript uses needs to be set explicitly and not conflict with any pre-set variables.
|

# Variables that we might change will be saved in preset_x and variables we use will be copied into l_x.
