hard coded value for idcode field in struct cpu_table

Dear All, I do not understand the value of idcode field in the struct cpu_table i.e. the value is hard coded. I did not find that value in the user manuals, also. The code is available at linux/arch/arm/plat-s3c24xx/cpu.c file. Currently, I am trying to implement the code for Samsung S3C2510A processor which is not available in the current sources. Where can I find the idcode value for Samsung S3C2510A processor? Any ideas will be appreciated. Thanks and Regards, Madhavi M.
