Hi,

I am using a very old version  of uboot the following is the modification I
made to disable command line access in uboot

1) disable all autoboot options like AUTOBOOT_KEYED, AUTOBOOT_PROMPT,
AUTOBOOT_DELAY_STR, AUTOBOOT_STOP_STR, AUTOBOOT_KEYED_CTRLC

2) In common/autoboot.c file I am unconditionally calling disable_ctrlc(1)
before the call to run_command_list(s, -1, 0) in the function
autoboot_command()

Can someone confirm directly calling disable_ctrlc(1) is OK and that no
other key combination  will stop the execution? I just don't want users to
modify any thing on the bootloader prompt and so disabling the access
completely to cmd prompt.

Regards
Fariya
