I am setting up my device to autoboot, and I want to compile in a default boot command (a la CONFIG_BOOTCOMMAND) and only use the bootcmd variable if it is defined. I want to use the other environment for other things, though.
It appears to me, though, that in main.c autoboot will be prevented if getenv("bootcmd") returns 0, no matter what the CONFIG_BOOTCOMMAND value is set.
Am I mis-reading this? Is this an error in need of fixing?
Arg! It seems like *all* the autoboot related variables, including BOOTARGS and AUTOBOOT_PROMPT are ignored if there is *any* environment. This makes no sense to me. Surely people want to set per-board stuff in environment and keep common autoboot settings compiled in. My BOOTCOMMAND and BOOTARGS together are too large to fit into my 256byte EEPROM.
