From 16a6d8a674fb9ebc86dec77b50dbe74dabd9beeb Mon Sep 17 00:00:00 2001 From: Enrico Jorns Date: Mon, 21 Sep 2015 16:04:43 +0200 Subject: mtd denali: pass col argument to READID operation A read id operation followed by 0x00 reads the device ID while a read id operation followed by 0x20 reads the possible ONFI identifier. As the READID function did not propagate the second id parameter but had a hard-coded call for 0x90 0x00, reading the ONFI identifier was not possible and thus chips werde not detected (tested with MT29F8G08ABABAWP) Signed-off-by: Enrico Jorns Signed-off-by: Sascha Hauer --- drivers/mtd/nand/nand_denali.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/mtd/nand/nand_denali.c') diff --git a/drivers/mtd/nand/nand_denali.c b/drivers/mtd/nand/nand_denali.c index a334dfb42e..d2e51e2568 100644 --- a/drivers/mtd/nand/nand_denali.c +++ b/drivers/mtd/nand/nand_denali.c @@ -1251,7 +1251,7 @@ static void denali_cmdfunc(struct mtd_info *mtd, unsigned int cmd, int col, */ addr = MODE_11 | BANK(denali->flash_bank); index_addr(denali, addr | 0, 0x90); - index_addr(denali, addr | 1, 0); + index_addr(denali, addr | 1, col); for (i = 0; i < 8; i++) { index_addr_read_data(denali, addr | 2, &id); write_byte_to_buf(denali, id); -- cgit v1.2.3
