[U-Boot] One basic U-boot question

[Martin Peevski]

     Hello, I have the following question. It is about the adresses 
where the U-boot and  Linux Kernel are copyed in the SDRAM from NAND.

     In my board config file I have:
     #define CONFIG_SYS_LOAD_ADDR        0x22000000    /* load address */
     Is that the load address of the U-boot?

     Also where is defined the load address of the Kernel because may be 
I need to leave more free space about the Kernel and RootFS?

     Thanks in advance!
