[U-Boot] About Die ID When Booting u-boot

[huadong2008]

Hi,
I'm studying porting Android onto Beagleboard(OMAP3530 based).
When booting u-boot version 2009 11 from SD card, the terminal show "Die ID #7fa200030000000004013f7806011011 ".
Could you please tell me what is Die ID? Or where can I download relative document about it?

I'm sorry for my poor English, and hope it will not puzzle you.
