mtd: nand: don't use read_buf for 8-bit ONFI transfers
Use a repeated read_byte() instead of read_buf(), since for x16 buswidth devices, we need to avoid the upper I/O[16:9] bits. See the following commit for reference: commit 05f7835975dad6b3b517f9e23415985e648fb875 Author: Uwe Kleine-König <[email protected]> Date: Thu Dec 5 22:22:04 2013 +0100 mtd: nand: don't use {read,write}_buf for 8-bit transfers Now, I think that all barriers to probing ONFI on x16 devices are removed, so remove the check from nand_flash_detect_onfi(). Tested on 8-bit ONFI NAND (Micron MT29F32G08CBADAWP). Signed-off-by: Brian Norris <[email protected]> Tested-by: Ezequiel Garcia <[email protected]> Tested-By: Pekon Gupta <[email protected]>
