[U-Boot] bootstopkey reason behind it

[Paavaanan_T_N at Dell.com]

Hi,

To stop autoboot we have 2 ifdef  (CONFIG_AUTOBOOT_STOP_ [STR2 || STR1] ). Which is very easy and straightforward to implement. Halting a boot with single "Keystroke" is having its own advantages to the user. But, why multiple key support is ignored say like [ctrl + anykey ] combination. Especially, BIOS vendors prefer at least simultaneous pressing of 2 or more keys to halt the boot. Any specific reasons to avoid this. Other than simplicity is there any specific reason to stick on this.

I mean why  simultaneous two key press support is avoided and implemented  a secondary bootstopkey to halt the boot say like CONFIG_AUTOBOOT_STOP_STR2.

Thanks,
Paavaanan.
