Subject: Revert "boot cmds: convert to getenv_yesno() with autostart"
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=3e5ab1af245da25633954c5b51c85cc8da0a5036;p=project%2Fbcm63xx%2Fu-boot.git

Revert "boot cmds: convert to getenv_yesno() with autostart"

This reverts commit 5a442c0addc69d0c4b58e98e5aec1cf07576debb.

This commit changed the behaviour of getenv_yesno() (both the default
behaviour and the documented behaviour for abbreviated arguments)
which resulted in problems in several areas.
