Flashmagic requests transfers to ram address 0x10000200 so if 0x10000000 is set as the start of the ram there is a potential that program memory gets clobbered (most likely the stack since we don't use 0x200 bytes of variables).

So we put the ethernet ram into the second segment at 0x2007C000 and start the main ram at 0x1000 to avoid that problem.
