mtd: nand: raw: convert nand_dt_init() to ofnode_xx() interface

2021-09-28T16:03:21+00:00

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

arm: Remove spear600 boards and the rest of SPEAr support

2021-07-08T02:22:42+00:00

These boards have not been converted to CONFIG_DM_USB by the deadline and is also missing conversion to CONFIG_DM. Remove them. As this is the last of the SPEAr platforms, so remove the rest of the remaining support as well. Cc: Vipin Kumar Signed-off-by: Tom Rini

mtd: nand: NFC drivers for RK3308, RK2928 and others

2021-06-18T06:37:20+00:00

This driver supports Rockchip NFC (NAND Flash Controller) found on RK3308, RK2928, RKPX30, RV1108 and other SOCs. The driver has been tested using 8-bit NAND interface on the ARM based RK3308 platform. Support Rockchip SoCs and NFC versions: - PX30 and RK3326(NFCv900). ECC: 16/40/60/70 bits/1KB. CLOCK: ahb and nfc. - RK3308 and RV1108(NFCv800). ECC: 16 bits/1KB. CLOCK: ahb and nfc. - RK3036 and RK3128(NFCv622). ECC: 16/24/40/60 bits/1KB. CLOCK: ahb and nfc. - RK3066, RK3188 and RK2928(NFCv600). ECC: 16/24/40/60 bits/1KB. CLOCK: ahb. Supported features: - Read full page data by DMA. - Support HW ECC(one step is 1KB). - Support 2 - 32K page size. - Support 8 CS(depend on SoCs) Limitations: - No support for the ecc step size is 512. - Untested on some SoCs. - No support for subpages. - No support for the builtin randomizer. - The original bad block mask is not supported. It is recommended to use the BBT(bad block table). Signed-off-by: Yifeng Zhao Reviewed-by: Kever Yang

Merge tag 'u-boot-atmel-2021.10-a' of https://source.denx.de/u-boot/custodians/u-boot-atmel into next

2021-06-17T15:46:44+00:00

First set of u-boot-atmel features for the 2021.10 cycle: This feature set converts the boards pm9261 and pm9263 Ethernet support to DM; enables hash command for all SAM boards; fixes the NAND pmecc bit-flips correction; adds Falcon boot for sama5d3_xplained board; and other minor adjustments.

nand: atmel: Correct bitflips in erased pages

2021-06-07T08:01:40+00:00

Not correcting anything in case of empty ECC data area is not an appropriate strategy, because an uncorrected bit-flip in an empty sector may cause upper layers (namely UBI) fail to work properly. Therefore the approach chosen in Linux kernel and other u-boot mtd drivers has been adopted, where a heuristic implemented by nand_check_erased_ecc_chunk() is used in order to detect and correct empty sectors. Tested with sama5d3_xplained and sam9x60-ek.

mtd: Update fail_addr when erase fails due to bad blocks

2021-04-12T21:17:11+00:00

For all other erase failures, the fail_addr is updated with the failing address. Only in the case of erase failure due to bad block detection, the fail_addr is not updated. This change simply updates the fail_addr for this specific scenario so that it is consistent with the rest of the code. Signed-off-by: Farhan Ali

spl: fit: nand: allow for non-page-aligned elements

2021-04-08T18:29:53+00:00

Add a weak nand_get_mtd function for nand drivers to provide mtd info and use this to set pagesize such that reading of non page-aligned elements can succeed. The spl_load_simple_fit already handles block block access so all we need to do is provide the nand writesize as the block length. Further cleanup of the drivers which use nand_spl_loaders.c such as am335x_spl_bch.c, atmel_nand.c, and nand_spl_simple.c could be done using info from mtd_info instead of statically defined details.
