Subject: [U-Boot-Users] Question about CFG_ENV_ADDR during RAMBOOT

On a lot of boards, if CFG_RAMBOOT is defined, the following code is compiled:

   #define CFG_ENV_ADDR		(CFG_MONITOR_BASE - 0x1000)
   #define CFG_ENV_SIZE		0x2000

This means that the environment is stored 0x1000 bytes before the start of u-boot.bin. 
Doesn't that mean that if the environment is larger than 0x1000 bytes, that it will 
overwrite the beginning of u-boot.bin whenever someone does a saveenv?
