2024-08-28mtd: rawnand: nand_base: support for 'NAND_IS_BOOT_MEDIUM' flagArseniy Krasnov
Based on Linux kernel: commit f922bd798bb9 ("mtd: rawnand: add an option to specify NAND chip as a boot device") Allow to define a NAND chip as a boot device. This can be helpful for the selection of the ECC algorithm and strength in case the boot ROM supports only a subset of controller provided options.

2024-04-14mtd: nand: raw: Port another option flag from LinuxAlexander Dahl
Introduced in upstream Linux with commit 7a08dbaedd365 for release v5.0. When the new atmel nand driver was backported to U-Boot with commit 6a8dfd57220d ("nand: atmel: Add DM based NAND driver") that definition was added to the driver instead of the header file. Move it over to the other definitions with the same help text it has in Linux. Code actually using this has not been ported over to raw nand base yet.

2021-09-28mtd: nand: raw: convert nand_dt_init() to ofnode_xx() interfacePatrice Chotard
nand_dt_init() is still using fdtdec_xx() interface. If OF_LIVE flag is enabled, dt property can't be get anymore. Updating all fdtdec_xx() interface to ofnode_xx() to solve this issue. For doing this, node parameter type must be ofnode. First idea was to convert "node" parameter to ofnode type inside nand_dt_init() using offset_to_ofnode(node). But offset_to_ofnode() is not bijective, in case OF_LIVE flag is enabled, it performs an assert(). So, this leads to update nand_chip struct flash_node field from int to ofnode and to update all nand_dt_init() callers. Signed-off-by: Patrice Chotard <patrice.chotard@foss.st.com>
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 <sjg@chromium.org>
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.

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 <trini@konsulko.com>
