mtd: spi-nor: Get rid of nor->page_size

2022-01-27T11:01:42Z

[ Upstream commit 5854d4a6cc356ba3e16d8593ac1c089a32d1759c ] nor->page_size duplicated what nor->params->page_size indicates for no good reason. page_size is a flash parameter of fixed value and it is better suited to be found in nor->params->page_size.

mtd: rawnand: Export nand_read_page_hwecc_oob_first()

2022-01-27T11:01:18Z

commit d8466f73010faf71effb21228ae1cbf577dab130 upstream. Move the function nand_read_page_hwecc_oob_first() (previously nand_davinci_read_page_hwecc_oob_first()) to nand_base.c, and export it as a GPL symbol, so that it can be used by more modules.

mtd: Remove obsolete macros only used by the old nand_ecclayout struct

2021-09-14T17:34:28Z

All uses of MTD_MAX_{OOBFREE,ECCPOS}_ENTRIES_LARGE have been removed as commit ef5eeea6e911 ("mtd: nand: brcm: switch to mtd_ooblayout_ops") and commit aab616e31d1c ("mtd: kill the nand_ecclayout struct") replaced struct nand_ecclayout by the new mtd_ooblayout_ops interface. Remove these two macros therefore. Reported-by: Yi Yang Signed-off-by: GONG, Ruiqi Signed-off-by: Miquel Raynal Link: https://lore.kernel.org/linux-mtd/20210830083356.31702-1-gongruiqi1@huawei.com

Due to possible mode switching to 8D-8D-8D, it might not be possible to read the SFDP after the initial probe. To be able to dump the SFDP via sysfs afterwards, make a complete copy of it.

mtd: spinand: use the spi-mem poll status APIs

Make use of spi-mem poll status APIs to let advanced controllers optimize wait operations. This should also fix the high CPU usage for system that don't have a dedicated STATUS poll block logic.

mtd: rawnand: Add a helper to parse the gpio-cs DT property

2021-05-26T14:26:32Z

New chips may feature a lot of CS because of their extended length. As many controllers have been designed a decade ago, they usually only feature just a couple. This does not mean that the entire range of these chips cannot be accessed: it is just a matter of adding more GPIO CS in the hardware design. A DT property has been added to describe the CS array: cs-gpios. Here is the code parsing it this new property, allocating what needs to be, requesting the GPIOs and returning an array with the additional available CS. The first entries of this array are left empty and are reserved for native CS. Signed-off-by: Miquel Raynal Link: https://lore.kernel.org/linux-mtd/20210526093242.183847-3-miquel.raynal@bootlin.com

Before adding a new function and to make it clear: move the declaration to the top of the file.
