Revision number in /proc/cpuinfo query

Hi,
I am using last 2.6.30 kernel in a custom i.MX27 base platform.

mx27# cat /proc/cpuinfo
Processor       : ARM926EJ-S rev 4 (v5l)
BogoMIPS        : 199.88
Features        : swp half thumb fastmult edsp java
CPU implementer : 0x41
CPU architecture: 5TEJ
CPU variant     : 0x0
CPU part        : 0x926
CPU revision    : 4

Hardware        : Vista Silicon Visstrim_M10
Revision        : 0000
Serial          : 0000000000000000

As i found in the code, Revision is the value of the global variable
"system_rev", but I have noticed that only the pxa boards, magician
and viper use this code.

Is it legal to add my own desired Revision code in my board file or
should I respect some standard numbers for ARM?

Thank you.
