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 Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Stefan Roese <sr@denx.de> Acked-by: Igor Grinberg <grinberg@compulab.co.il> Reviewed-by: Simon Glass <sjg@chromium.org> Acked-by: Vladimir Zapolskiy <vz@mleia.com> Reviewed-by: Heiko Schocher <hs@denx.de> Acked-by: Christian Riesch <christian.riesch@omicronenergy.com> Acked-by: Hannes Schmelzer <hannes.schmelzer@br-automation.com>
