* mtd: nand: move raw NAND related code to the raw/ subdirBoris Brezillon2018-02-161-207/+0

| | | | | | | | | | | | | | | | | | | | | | | | We are planning to share more code between different NAND based devices (SPI NAND, OneNAND and raw NANDs), but before doing that we need to move the existing include/linux/mtd/nand.h file into include/linux/mtd/rawnand.h so we can later create a nand.h header containing all common structure and function prototypes.

* mtd: nand: Do not expose the NAND manufacturer table directlyBoris Brezillon2017-03-081-2/+20
| | | | | | | | | | | | | | | There is no reason to expose the NAND manufacturer table. Provide an helper function to find manufacturers by their id. We also turn the nand_manufacturers table into a const array, since its members are not modified after the initial assignment. Finally, we remove the sentinel manufacturer entry from the manufacturers table (we already have the array size information given by ARRAY_SIZE()), and add the nand_manufacturer_name() helper to handle the "Unknown" case properly.

* mtd: nand: Kill the MTD_NAND_IDS Kconfig optionBoris Brezillon2017-03-081-7/+0
| | | | | | | | | | | | | MTD_NAND_IDS is selected by MTD_NAND, which makes it useless. Remove the Kconfig option and link nand_ids.o into the nand.o object file. Doing that also prevents creating an extra nand_ids.ko module when MTD_NAND is activated as a module. Since nand_ids.c is no longer compiled as a standalone module and the nand_manuf_ids/nand_flash_ids symbols are only used in nand_base.c, we can get rid of the MODULE_XXX() and EXPORT_SYMBOL() definitions.

| | | | | | | | | | | | | | | We have only one AG-AND driver and it was not touched since 2005. It looks like AG-AND was not really make it to mass-production and can be considered a dead technology. Along with the AG-AND support, this patch removes the BBT_AUTO_REFRESH feature, because the only user of this feature is AG-AND. And even though it is implemented as a generic feature, I prefer to remove it because NAND flashes do not really need it in this form.

* mtd: decommission the NAND museumArtem Bityutskiy2013-04-051-17/+5
| | | | | | | | | | | | | | | | | | | | The MTD subsystem has its own small museum of ancient NANDs in a form of the CONFIG_MTD_NAND_MUSEUM_IDS configuration option. The museum contains stone age NANDs with 256 bytes pages, as well as iron age NANDs with 512 bytes per page and up to 8MiB page size. It is with great sorrow that I inform you that the museum is being decommissioned. The MTD subsystem is out of budget for Kconfig options and already has too many of them, and there is a general kernel trend to simplify the configuration menu. We remove the stone age exhibits along with closing the museum, but some of the iron age ones are transferred to the regular NAND depot. Namely, only those which have unique device IDs are transferred, and the ones which have conflicting device IDs are removed.

* mtd: nand: reintroduce NAND_NO_READRDY as NAND_NEED_READRDYBrian Norris2013-03-141-39/+41
| | | | | | | | | | | | | | | | | | | | | | | | | This partially reverts commit 1696e6bc2ae83734e64e206ac99766ea19e9a14e ("mtd: nand: kill NAND_NO_READRDY"). In that patch I overlooked a few things. The original documentation for NAND_NO_READRDY included "True for all large page devices, as they do not support autoincrement." I was conflating "not support autoincrement" with the NAND_NO_AUTOINCR option, which was in fact doing nothing. So, when I dropped NAND_NO_AUTOINCR, I concluded that I then could harmlessly drop NAND_NO_READRDY. But of course the fact the NAND_NO_AUTOINCR was doing nothing didn't mean NAND_NO_READRDY was doing nothing... So, NAND_NO_READRDY is re-introduced as NAND_NEED_READRDY and applied only to those few remaining small-page NAND which needed it in the first place.

| | | | | | | | | | | | | | | | | | | | | Toshiba does not use ONFI for their NAND flash. So we have to continue to add new IDs used by Toshiba devices as well as heuristic detection for scanning the 2nd page for a BBM. This is a relatively harmless start at supporting many of them. These chips mostly follow the same ID fields of previous generations, but there is a need for a tweak. These chips introduce a strange 576 byte OOB (that's 36 bytes per 512 bytes of page). In the preliminary data, Toshiba has not defined exactly how their ID strings should decode. In the future, a new tweak must be added.
