mtd: rawnand: stm32_fmc2: set available OOB bytes per page

2025-08-25T14:47:04Z

File system such as YAFFS2 need to know the number of available OOB bytes per page to be able to choose if they should locate their metadata in the data area or in the spare area. Signed-off-by: Christophe Kerello Reviewed-by: Patrice Chotard

mtd: nand: Do not dereference before NULL check

2025-08-23T14:37:26Z

In nanddev_init mtd and memorg are assigned values that dereference nand but this happens before a NULL check for nand. Move the assignments after the NULL check. This issue was found by Smatch. Signed-off-by: Andrew Goodbody Signed-off-by: Michael Trimarchi

mtd: nand: cadence: Fix device assignment to avoid warm reset issue

2025-08-23T14:37:05Z

The driver currently does: mtd->dev->parent = cadence->dev; This works in Linux because `struct mtd_info` embeds a `struct device`, so `mtd->dev` is always valid and its `.parent` can be set. In U-Boot, however, `mtd->dev` is only a pointer to a `struct udevice`. Dereferencing it before assignment is invalid, which breaks the device hierarchy. As a result, consumers relying on `mtd->dev` (e.g. partition parser, reset and re-init paths) operate on a dangling pointer. This leads to failures during warm reset when the NAND device is accessed again. Fix by assigning the device pointer directly: mtd->dev = cadence->dev; This matches U-Boot’s device model, preserves a valid hierarchy, and resolves the warm reset issue on Cadence NAND.

mtd: spi-nor: Fix return value of s25_s28_mdp_ready()

2025-08-07T17:14:35Z

s25_s28_mdp_ready() returns 1 when spansion_sr_ready() returns negative value (error code). Fix this problem by following Linux implementation.

mtd: rawnand: mxs_nand: Ensure err is set for error path

2025-08-03T08:22:04Z

In mxs_nand_init_ctrl there are a couple of error paths that do not set err which could lead to the errors being silently ignored despite the function not completing. Rather than just using if to detect these errors use err to collect the error return value from the called functions. This issue was found by Smatch.

In denali_wait_for_irq the code will either return from inside the while loop or exit with time_left being 0. The following test for time_left being 0 is guranteed to be true so remove the test and the following unreachable code. This issue was found by Smatch.
