[U-Boot] Uboot_Header_Modification_by_CVS

[Arun K. Varghese]

Hi,

Issue.
-------

1) Downloaded u-boot-2010.09 source code. (u-boot-2010.09.tar.bz2<http://ftp.denx.de/pub/u-boot/u-boot-2010.09.tar.bz2>)
2) Some files, have version & header information along with the source code.

Ex:
1)      In  u-boot-2010.09/arch/arm/cpu/ixp/npe/include/IxI2cDrv.h

 * @version $Revision: 0.1 $

2)      In u-boot-2010.09/arch/i386/cpu/sc520/sc520_asm.S

 * $Revision: 1.2 $
 * $Date: 1999/09/22 12:49:33 $
 * $Author: chipf $

3) When I do a check in for these files, using CVS, these header information is changed.
CVS is  automatically modifying these headers.

Eg :

In u-boot-2010.09/arch/i386/cpu/sc520/sc520_asm.S

 * $Revision: 1.2 $
 * $Date: 1999/09/22 12:49:33 $
 * $Author: chipf $

If I do a check in, it will be changed to

 * $Revision: 1.1.1.2 $
 * $Date: 2013/12/16 12:49:33 $
 * $Author: Arun $

Doubts
---------

1. Why only few files have these kind of header information in Uboot repository ?

2. If I do a check in via CVS, the headers will be modified,
   So will it be a violation to GPL ?

3.  If it is a Violation , please help me with a solution .

Thanks & Regards,
Arun
