treewide: Kconfig: use bool instead of tristate

2026-07-10T21:45:57Z

U-Boot does not support modules, so having tristate options is useless. Therefore this patch does a blind replace of all tristate options to bool tree-wide.

mtd: nand: raw: rockchip_nfc: fix oobfree length calculation

2026-07-09T17:49:22Z

The oobfree[0].length calculation depends on the rknand->metadata_size value, but this is calculated after the function rk_nfc_ecc_init is called. Move this calculation to a location before it's value is required.

mtd: nand: raw: sunxi: #undef field_{get, prep}() before definition

2026-07-08T19:29:18Z

Prepare for the advent of globally available common field_get() and field_prep() macros by undefining the symbols before defining local variants. This prevents redefinition warnings from the C preprocessor when introducing the common macros later. Signed-off-by: Mikhail Kshevetskiy

mtd: nand: pxa3xx: Pass valid dev to dev_err()

2026-06-10T09:23:26Z

info->controller.active is not initialised so the dev_err() call ends up dereferencing a null pointer causing a crash instead of outputting the error. Add a dev member to struct pxa3xx_nand_info and use that instead of info->controller.active->mtd.dev.

mtd: nand: raw: sunxi_spl: remove user data length reset

No need to reset user data length registers in SPL. In SPL, only the first user data length register is used, so we don't need to reset all of them. Signed-off-by: Richard Genoud Acked-by: Andre Przywara

mtd: rawnand: sunxi: introduce variable user data length

2026-05-01T12:49:44Z

In Allwinner SoCs, user data can be added in OOB before each ECC data. For older SoCs like A10, the user data size was the size of a register (4 bytes) and was mandatory before each ECC step. So, the A10 OOB Layout is: [4Bytes USER_DATA_STEP0] [ECC_STEP0 bytes] [4bytes USER_DATA_STEP1] [ECC_STEP1 bytes] ... NB: the BBM is stored at the beginning of the USER_DATA_STEP0. Now, for H6/H616 NAND flash controller, this user data can have a different size for each step. So, we are maximizing the user data length to use as many OOB bytes as possible.
