Subject: common/main: support bootdelay=0 for CONFIG_AUTOBOOT_KEYED
X-Git-Tag: v2009.03-rc1~182
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=c3284b030b1cd492b4f46c576aea01bef258599d;p=oweals%2Fu-boot.git

common/main: support bootdelay=0 for CONFIG_AUTOBOOT_KEYED

Support bootdelay=0 in abortboot for the CONFIG_AUTOBOOT_KEYED case
similar to the CONFIG_ZERO_BOOTDELAY_CHECK support for the
!CONFIG_AUTOBOOT_KEYED case.

Do this by reversing the loop so we do at least one iteration before
checking for timeout.
