Boot through NAND and not through SD Card

Kaushik Kale
I am using a tiny6410 board. Is it required to run the linux or other OS
through SD Card or is it also possible to do that from the internal storage
memory.

I just want to know if I am required to always use a SD Card or I have an
option of transferring the boot process to the Nand memory or any other
internal memory.
