2020-05-18arm: Don't include common.h in header filesSimon Glass
It is bad practice to include common.h in other header files since it can bring in any number of superfluous definitions. It implies that some C files don't include it and thus may be missing CONFIG options that are set up by that file. The C files should include these themselves. Update some header files in arch/arm to drop this. Signed-off-by: Simon Glass <[email protected]>
2019-04-22mtd: nand: provide several helpers to do common NAND operationsBoris Brezillon
Linux commit 97d90da8a88 ("mtd: nand: provide several helpers to do common NAND operations") This is part of the process of removing direct calls to ->cmdfunc() outside of the core in order to introduce a better interface to execute NAND operations. Here we provide several helpers and make use of them to remove all direct calls to ->cmdfunc(). This way, we can easily modify those helpers to make use of the new ->exec_op() interface when available.

Linux commit d45bc58dd3b ("mtd: nand: import nand_hw_control_init()") The code to initialize a struct nand_hw_control is duplicated across several drivers. Factorize it using an inline function.

2019-04-22mtd: add get/set of_node/flash_node helpersBrian Norris
Linux commit 28b8b26b308 ("mtd: add get/set of_node/flash_node helpers") We are going to begin using the mtd->dev.of_node field for MTD device nodes, so let's add helpers for it. Also, we'll be making some conversions on spi_nor (and nand_chip eventually) too, so get that ready with their own helpers.

2018-07-23mtd: nand: add new enum for storing ECC algorithmRafał Miłecki
Our nand_ecc_modes_t is already a bit abused by value NAND_ECC_SOFT_BCH. This enum should store ECC mode only and putting algorithm details there is a bad idea. It would result in too many values impossible to support in a sane way. To solve this problem let's add a new enum. We'll have to modify all drivers to set it properly but once it's done it'll be possible to drop NAND_ECC_SOFT_BCH. That will result in a cleaner design and more possibilities like setting ECC algorithm for hardware ECC mode.

2018-06-27mtd: nand: export nand_get_flash_type functionJörg Krause
`nand_get_flash_type()` allows identification of supported NAND flashs. The function is useful in SPL (like mxs_nand_spl.c) to lookup for a NAND flash (which does not support ONFi) instead of using nand_simple.c and hard-coding all required NAND parameters.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <[email protected]>

2017-12-04mtd: nand: Rename nand.h into rawnand.hMasahiro Yamada
This header was renamed to rawnand.h in Linux. The following is the corresponding commit in Linux. commit d4092d76a4a4e57b65910899948a83cc8646c5a5 Author: Boris Brezillon <[email protected]> Date: Fri Aug 4 17:29:10 2017 +0200 mtd: nand: Rename nand.h into rawnand.h 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.
