From: Wolfgang Grandegger wg@grandegger.com
The 'N' type Spansion flashes (S29GLxxxN series) have bigger sectors, than the formerly used 'M' types (S29GLxxxM series), so the flash layout needs to be changed -> new start address of the environment. The macro definition CONFIG_TQM_FLASH_N_TYPE is undefined by default and must be defined for boards with 'N' type flashes.
