As the help message of CONFIG_BOOTDELAY says, CONFIG_BOOTDELAY=-2
means the autoboot with no delay, with no abort check even if
CONFIG_ZERO_BOOTDELAY_CHECK is defined.
To sum up, the autoboot behaves as follows:
[1] CONFIG_BOOTDELAY=0 && CONFIG_ZERO_BOOTDELAY_CHECK=y
autoboot with no delay, but you can abort it by key input
[2] CONFIG_BOOTDELAY=0 && CONFIG_ZERO_BOOTDELAY_CHECK=n
autoboot with no delay, with no check for abort
[3] CONFIG_BOOTDELAY=-1
disable autoboot
[4] CONFIG_BOOTDELAY=-2
autoboot with no delay, with no check for abort
As you notice, [2] and [4] come to the same result, which means we
do not need CONFIG_ZERO_BOOTDELAY_CHECK. We can control all the
cases only by CONFIG_BOOTDELAY, like this:
[1] CONFIG_BOOTDELAY=0
autoboot with no delay, but you can abort it by key input
[2] CONFIG_BOOTDELAY=-1
disable autoboot
[3] CONFIG_BOOTDELAY=-2
autoboot with no delay, with no check for abort
This commit converts the logic as follow:
CONFIG_BOOTDELAY=0 && CONFIG_ZERO_BOOTDELAY_CHECK=n
--> CONFIG_BOOTDELAY=-2
