2021-06-18mtd: rawnand: omap: Check return valuesMiquel Raynal1-9/+21
Check the return value of many helpers which might return error codes. Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com> Link: https://lore.kernel.org/linux-mtd/20210610134906.3503303-4-miquel.raynal@bootlin.com
2021-06-18mtd: rawnand: omap: Rename a macroMiquel Raynal1-8/+8
The macro BADBLOCK_MARKER_LENGTH is pretty long and could be reduced to BBM_LEN which is more handy to use in the code. This is a purely cosmetic change and is only done to avoid further change to contain 100+ char lines just because of this definition.

2021-06-18mtd: rawnand: omap: Aggregate the HW configuration of the ELMMiquel Raynal1-19/+11
Instead of calling elm_config() for each possible BCH configuration, just save the BCH configuration that must be applied and use it in a single call at the bottom.

2021-06-18mtd: rawnand: pl353: Add support for the ARM PL353 SMC NAND controllerMiquel Raynal3-0/+1203
This hardware controller is embedded in XilinX Zynq-7000 SoCs and has partial support for Hamming ECC correction. This work is inspired from the original contributions of Punnaiah Choudary Kalluri and Naga Sureshkumar Relli.
