Hi,
This field is defined for example in this datasheed:

http://www.alldatasheet.com/datasheet-pdf/pdf/84872/SAMSUNG/S3C2410A.html

PDF page 282:

GENERAL STATUS REGISTER (GSTATUSn)
Register Address R/W Description Reset Value
GSTATUS0 0x560000AC R External pin status Undefined

>>>>>   GSTATUS1 0x560000B0 R Chip ID 0x32410000 <<<

GSTATUS2 0x560000B4 R/W Reset status 0x1
GSTATUS3 0x560000B8 R/W Infrom register 0x0
GSTATUS4 0x560000BC R/W Infrom register 0x0

This is "GSTATUS1" register initial value


I don't think that S3c25 are so similar to S3c25, so they provide
exactly the same method of chip identification.
