Hello,

I have seen that the new trunk code has some substantial changes to 
Netgear WNDR3700/4300 memory map configuration.

The Makefile used to hold the memory maps and that now has disappeared 
thus the following patch that I created to get the whole flash for the 
filesystem no longer applies:

Please could you let me know how do I remap the flash memory now?

Thank you in advance.
