Subject: [U-Boot] [PATCH] Seperate mtdpart command from jffs2

Hi Kyungmin,

I tried to rephrase this description a little bit:

"
Currently the mtdparts commands are included in the jffs2 command support. 
This doesn't make sense anymore since other commands (e.g. UBI) use this 
infrastructure as well now. This patch separates the mtdparts commands from 
the jffs2 commands making it possible to only select mtdparts when no JFFS2 
support is needed.
"

If you don't have any objections I suggest to use this description in your 
next patch version.

Please find some more comments below.

Shouldn't we change this define (CONFIG_JFFS2_CMDLINE) to something else now, 
since it's not really JFFS2 specific anymore? I suggest to change it to 
CONFIG_CMD_MTDPARTS. This seems more logical to me.

What do you think? 

This patch also breaks (at least some) boards with JFFS2 support:

[stefan at kubuntu u-boot (master)]$ ./MAKEALL fx12mm
Configuring for fx12mm board...
cmd_jffs2.c:164: warning: 'device_validate' defined but not used

I didn't try to solve this problem (yet). Perhaps you have an idea?

Thanks.

Best regards,
Stefan
