AM3356 -custom board with NAND flash memory only

Other Parts Discussed in Thread: AM3356

Hi,

AM3356 -custom board .

What are the changes required for a custom board with NAND flash memory only ? I am going to modify uboot and spl shipped along with SK7.0 .
My boot configuration is 

SYSBOOT[15:14]  - 01b -- 24Mhz
SYSBOOT[13:12]  - 00b -- reserved
SYSBOOT[11:10]  - 00b -- nand boot
SYSBOOT[9]         - 0b --ECC handled bu ROM
SYSBOOT[8]         -        dont care by rom - NC
SYSBOOT[7:6]      -       dont care by rom - NC
SYSBOOT[5]         - 0b        clock out disabled
SYSBOOT[4:0]     - 10010b    boot sequence  NAND,NANDI2C,USB0,UART0

So ROM code will initially check for SPL [MLO binary] @0x00000000 NAND flash and execute.

I know that I have to make changes in SPL so that spl will check for uboot @0x00080000 of nand flash .
What are changes I have to do ? can anyone point out specific files in which I have to make changes ?

Thanks and regards
