No, I mean in the NAND driver for your specific hardware (fsl_elbc_nand.c, mxc_nand.c, ndfc_nand.c, etc).
You have been so helpful. I looked at the mtd/nand/Makefile and the only file that's included besides the nand* files is:
COBJS-y += fsl_upm.o
You've got an old/out-of-tree u-boot.
I think we are just using the base/generic mtd nand driver. Is that possible?
No, there must be a controller driver. It may be in a board or cpu directory, though. Search for board_nand_init().
Its in board/atmel/at91sam9rlek/nand.c
It doesn't do much but set up the various GPIO connections. Here's the function:
int board_nand_init(struct nand_chip *nand) { nand->ecc.mode = NAND_ECC_SOFT; #ifdef CFG_NAND_DBW_16 nand->options = NAND_BUSWIDTH_16; #endif nand->cmd_ctrl = at91sam9rlek_nand_hwcontrol; nand->dev_ready = at91sam9rlek_nand_ready; nand->chip_delay = 20;
return 0; }
