From a0dc552951dcbb2b28a8a2ffb5fa966613e8c025 Mon Sep 17 00:00:00 2001 From: Brian Norris Date: Tue, 31 May 2011 16:31:20 -0700 Subject: mtd: nand: remove NAND_BBT_SCANBYTE1AND6 option This patch reverts most of: commit 58373ff0afff4cc8ac40608872995f4d87eb72ec mtd: nand: more BB Detection refactoring and dynamic scan options According to the discussion at: http://lists.infradead.org/pipermail/linux-mtd/2011-May/035696.html the NAND_BBT_SCANBYTE1AND6 flag, although technically valid, can break some existing ECC layouts that use the 6th byte in the OOB for ECC data. Furthermore, we apparently do not need to scan both bytes 1 and 6 in the OOB region of the devices under consideration; instead, we only need to scan one or the other. Thus, the NAND_BBT_SCANBYTE1AND6 flag is at best unnecessary and at worst a regression.

We should try to separate these two spaces a little more clearly, and so I have added a bbt_options field to nand_chip. Important notes about nand_chip fields: * bbt_options field should contain ONLY flags from bbm.h. They should be able to pass safely to a nand_bbt_descr data structure. - BBT option flags start with the "NAND_BBT_" prefix. * options field should contian ONLY flags from nand.h. Ideally, they should not be involved in any BBT related options. - NAND chip option flags start with the "NAND_" prefix. * Every flag should have a nice comment explaining what the flag is. While this is not yet the case on all existing flags, please be sure to write one for new flags. Even better, you can help document the code better yourself! Please try to follow these conventions to make everyone's lives easier. Among the flags that are being moved to the new bbt_options field throughout various drivers, etc. are: * NAND_BBT_SCANLASTPAGE * NAND_BBT_SCAN2NDPAGE and there will be more to come.

Flag (2) is simply the combination of (1) and (3) and can be eliminated. This patch accomplishes the following: * eliminate NAND_USE_FLASH_BBT_NO_OOB (i.e., flag (2)) * move NAND_USE_FLASH_BBT (i.e., flag (1)) to bbm.h It's important to note that because (1) and (3) are now both found in bbm.h, they should NOT be used in the "nand_chip.options" field. I removed a small section from the mtdnand DocBook because it referes to NAND_USE_FLASH_BBT in nand.h, which has been moved to bbm.h.

Particularly, MTD_OOB_RAW affected operations on in-band page data as well. To clarify these options and to emphasize that their effect is applied per-operation, we change the primary prefix to MTD_OPS_.

First, mtd->read_oob is being called in raw mode, so there should be no error correction in the first place. Second, if we change this such that there *is* error correction in this function, then we will want to pass the error message upward. In fact, the code I introduced to "ignore ECC errors" would have been better if it had just placed this test down in `scan_block_full()' in the first place. We would like to ignore ECC errors when we are simply checking for bad block markers (e.g., factory marked), but we may not want to ignore ECC errors when scanning OOB for a flash-based BBT pattern (in `scan_read_raw()'; note that the return codes from `scan_read_raw()' are not actually handled yet).

The NAND_BBT_NO_OOB option should not be set while scanning for bad blocks, but we've been passing all BBT options from nand_chip.bbt_options to the bad block scan. This causes us to hit the: BUG_ON(bd->options & NAND_BBT_NO_OOB); in create_bbt() when we scan the flash for bad blocks. Thus, while it can be legal to set NAND_BBT_NO_OOB in a custom badblock pattern descriptor (presumably with NAND_BBT_CREATE disabled?), we should not pass it through in our default function. Also, to help clarify and emphasize that the function creates bad block patterns only (not, for example, table descriptors for locating flash-based BBT), I renamed `nand_create_default_bbt_descr' to `nand_create_badblock_pattern'.

Since it's possible for `memcmp()' to be optimized for a particular architecture, we should use it instead.
