Dear Denk,
	Thanks for your help, and I do not make any progress till now.
Because during my test, my flash error!
	Because Atmel suggest with AT49BV322 or AT49BV642 to replace
AT49BV6416,
I modified the "flash.c" "flash.h" to support it. And my board with
AT49BV322DT,
This is top boot flash, and it work after modify the flash driver of uboot.
But it failed today, it looks like the Sector failed, but the second Sector
Can work still.
	Or should I use Bottom boot FLASH?
