[U-Boot-Users] [PATCH] bootretry enviroment variable

27 Nov 2003

Hi,
paste from the doc/README.autoboot
CONFIG_BOOT_RETRY_TIME
   CONFIG_BOOT_RETRY_MIN
bootretry environment variable
These options determine what happens after autoboot is
         stopped and U-Boot is waiting for commands.
CONFIG_BOOT_RETRY_TIME must be defined to enable the boot
         retry feature. If the environment variable 'bootretry' is
         found then its value is used, otherwise the retry timeout is
         CONFIG_BOOT_RETRY_TIME. CONFIG_BOOT_RETRY_MIN is optional and
         defaults to CONFIG_BOOT_RETRY_TIME. All times are in seconds.
If the retry timeout is negative, the U-Boot command prompt
         never times out. Otherwise it is forced to be at least
         CONFIG_BOOT_RETRY_MIN seconds. If no valid U-Boot command is
         entered before the specified time the boot delay sequence is
         restarted. Each command that U-Boot executes restarts the
         timeout.
end of paste from the doc/README.autoboot
Currently is used function simple_strtoul() for parsing the bootretry 
enviroment variable. It fails if the bootretry is negative. The attached 
patch should fix it.
