-Bloody hell... +Internal registers base address is set in register offset 0x20080 (arch-kirkwood/kirkwood.h): i.e. 0xF1020080 = 0xF1000000

-= Trying to find ENV in NAND = 
- 
-  I think it uses /* Use the new NAND code. */ in mv_kw.h 
-  And it also #undef CFG_ENV_IS_IN_FLASH which is interesting... 
-  Think only need ENV_SIZE and ENV_OFFSET when in NAND 
- 
-  #define CFG_ENV_OFFSET 0xA0000 (640 << 10) /* environment starts here  */ 
-  #define CFG_ENV_SECT_SIZE 0x20000 (128 << 10) /* environment take 1 block */
