[U-Boot-Users] Image date output from imls/iminfo when no rtc chip is present

[U-Boot-Users] Image date output from imls/iminfo when no rtc chip is present

[Tolunay Orkun]

Creation date of the U-Boot Image is suppressed from output of 
imls/iminfo commands if CFG_CMD_DATE is not included in CONFIG_COMMANDS.

However, CFG_CMD_DATE cannot be included unless you have an RTC chip on 
board.

I think the date of U-Boot image is useful information that we would 
like to see even if CFG_CMD_DATE is not defined.

To such end, I thought of the following solution:

Define CONFIG_RTC_NONE so that CFG_CMD_DATE could be defined. Obviously, 
date/time commands will display error message when user attempts to use 
these commands with CONFIG_RTC_NONE. I might even exclude the definition 
of date/time commands altogether keeping only supporting date 
functionality needed for imls/iminfo.

What do you think? If there is agreement on CONFIG_RTC_NONE, I can 
submit a patch...

Best regards,
Tolunay

No. That's only half of the story.

Which seems logical to me, as "date" is the command to read  and  set
the RTC.

Indeed.

I disagree. Just RTFM...

Quoting the README:

- Timestamp Support:
    
                When CONFIG_TIMESTAMP is selected, the timestamp
                (date and time) of an image is printed by image
                commands like bootm or iminfo. This option is
                automatically enabled when you select CFG_CMD_DATE .



Best regards,

When I read this I kind of got the impression CFG_CMD_DATE was needed. Sorry for the noise on this issue.
