[U-Boot-Users] board_nand_init

Hi,all
	I am trying to run u-boot-1.1.5 on my s3c2410_board,which has 32M SDRAM
and 64M NAND flash.i have enabled the CFG_CMD_NAND flag.when i make the
src the compiler report this 
"drivers/nand/libnand.a(nand.o): In function `nand_init':
/home/code/arm/u-boot-1.1.5/drivers/nand/nand.c:50: undefined reference
to `board_nand_init'
"
my problem is if i should init all functions and variables in the
nand_chip struct? if not what's my job in the board_nand_init?

You need to implement a board (or cpu) specific init function 
called "board_nand_init()" to init all functions and variables in the 
nand_chip struct. Take a look at cpu/ppc4xx/ndfc.c or 
board/prodrive/pdnb3/nand.c how this can be done.
