Lpc2000

Hi,
I am trying to write a bootloader for a development kit based on 
LPC2210. I have read some documents, from which I got to know I had to 
initialize the Flash, ARM, the system clock and the also one UART. 
After that, the bootloader should pass some kernel parameters to boot 
the Linux kernel, and also the Machine Type. Can anyone tell me how to 
abtain the Machine type with a algorithm? Any other method to get it?
And what's the Machine Type of LPC2210?

Please recommend me some useful documents on bootloader, thank you very 
much!

Regards,

Kevin
