[PATCH v8 0/4] mtd: devices: elm: add checks ELM H/W constrains, driver code cleanup

[Pekon Gupta]

*changes v7 -> v8*
Incorporated feedbacks from Brian Norris <computersforpeace at gmail.com>
 - renamed ecc_step_bytes -> ecc_syndrome_size


*changes v6 -> v7*
Incorporated feedbacks from Ezequiel Garcia <ezequiel.garcia at free-electrons.com>
 - using dev_err() instead of pr_err()
 - moved un-related addition of info->ecc_steps, info->ecc_step_bytes,
   info->ecc_step_size from [PATCH v6 1/4] into subsequent patches
 - dropped pr_fmt() change


*changes v5 -> v6*
[PATCH 02/04] minor cleanup

*changes v4 -> v5*
This patch series is split version from earlier series [1].
This series refactors and cleans ELM driver which is used by Hardware
based BCHx ecc-schemes.
 - Undo: introduction of 'struct mtd_info' and 'struct nand_chip'. Instead
         keep ELM driver independent of mtd_info and nand_chip structs and
         pass only required ECC configurations as elm_config() arguments
         elm_config(..., int ecc_steps, int ecc_step_size, int ecc_step_bytes)
 - Undo: re-writing of elm_load_syndrome() ECC register configurations.

*changes v3 -> v4 [1]*
 - in-corporated feedbacks from Brian Norris <computersforpeace at gmail.com>
 - updated: use 'pr_fmt(fmt)' to suffix DRIVER_NAME
 - removed: local 'eccsteps' in ELM driver, instead using nand_chip->ecc.steps
 - undo: irrelavant white-space changes
