Add support for the layout used by 2kiB page NAND chips requesting at least 8-bit of correction per 512 bytes. This layout requires a bit of handling as: 1/ It can only fit if the NAND chip has at least 128 OOB bytes. 2/ The Bad Block Markers are located in the middle of the data bytes and shall not be used. 3/ It has been experimentally observed that, for certain layouts, the ECC engine tries to correct data while it should not because the errors are uncorrectable. While this is harmless for truly bad pages, it creates bitflips in empty pages. To avoid such scenario that augments artificially the number of bitflips we re-read in raw mode the entire page instead of just the ECC bytes. This is done only for this layout to avoid an unneeded penalty with other setups. Signed-off-by: NMiquel Raynal <miquel.raynal@bootlin.com> Reviewed-by: NBoris Brezillon <boris.brezillon@bootlin.com>

We are about to support a new layout that triggers a faulty mechanism in BCH engine that creates bitflips in erased pages. Before adding the quirk that will workaround this issue, this patch just reworks a bit the section that handles ECC failures in BCH read path.

One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; void *entry[]; }; instance = devm_kzalloc(dev, sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = devm_kzalloc(dev, struct_size(instance, entry, count), GFP_KERNEL); This issue was detected with the help of Coccinelle.

Use SPDX-License-Identifier instead of the license boilerplates. This conversion makes it easier for us to scan the license, then I notice license mismatch problems. The license blocks in denali* indicate GPL-2.0 "only", while the MODULE_LICENSE in denali.c and denali_dt.c is GPL-2.0 "or later" as explained in include/linux/module.h as follows: "GPL" [GNU Public License v2 or later] "GPL v2" [GNU Public License v2] I fixed the MODULE_LICENSE tags, assuming the license blocks are the authors' intention. Also, add missing MODULE_DESCRIPTION/AUTHOR to denali.c While I am touching the license things, I added my credit to denali.c because this driver was largely re-written by me in 2017.

This patch is a patch to support TOSHIBA MEMORY CORPORATION BENAND memory devices. Check the status of the built-in ECC with the Read Status command without using the vendor specific command.

The marvell_nfc_init() function fiddles with some bits of a system controller on Armada 7K/8K. However, it does a read/modify/write sequence on GENCONF_CLK_GATING_CTRL and GENCONF_ND_CLK_CTRL, which isn't safe from a concurrency point of view, as the regmap lock isn't taken accross the read/modify/write sequence. To solve this issue, use regmap_update_bits(). While at it, since the "reg" variable is no longer needed for the read/modify/write sequences, get rid of it for the regmap_write() to GENCONF_SOC_DEVICE_MUX, and directly pass the value to be written as argument.
