I can tell you that these aree the physical addresses and size of the
SDRMA and flash memory, respective - but I *strongly* recommend  that
you  start reading the code. Using "grep" quickly reveals where these
definitions are used and what they do.

Learn to use the tools, or you will have to ask again and  again  and
again.

Read the code.
