The denali->blksperchip is set, but not referenced any more. The denali->totalblks is used only for calculating denali->blksperchip. Both of them are unneeded. Signed-off-by:

As far as I understood from the Kconfig menu deleted by commit be7f39c5 ("Staging: delete spectra driver"), the "Spectra" is specific to Intel Moorestown Platform. The Denali NAND controller IP is used for various SoCs such as Altera SOCFPGA, Socionext UniPhier, etc. The platform specific strings are not preferred in this driver. Signed-off-by:

The denali->fwblks is set by detect_partition_feature(), but it is not referenced from anywhere. That means the struct member fwblks and the whole of detect_partition_feature() are unneeded. The comment block implies this function is only for Intel platforms. I found drivers/staging/spectra used to exist, but it was deleted by commit be7f39c5 ("Staging: delete spectra driver") 5 years ago. So, I guess nobody would need this function any more.

The interrupt handler is setup in denali_init(), not in denali_drv_init(). This comment is false. Such a comment adds no value, so just delete it instead of move. Signed-off-by:

The struct member "idx" was used as an index for debug_array long ago, but the DEBUG_DENALI feature was removed by commit 7cfffac0 ("nand/denali: use dev_xx debug function to replace nand_dbg_print and some printk"). Since then, this has been only initialized, but never referenced. Signed-off-by:

The driver calls devm_kzalloc()/devm_kfree() to allocate/free memory. They are declared in <linux/device.h>, not in <linux/slab.h>. Signed-off-by:

For this driver, there is nothing between nand_scan_ident() and nand_scan_tail(). They can be merged into nand_scan(). Also, nand_scan() returns an appropriate error value when it fails. Use it instead of the fixed error code -ENXIO. Signed-off-by:

The nand_scan_ident() returns an appropriate error value when it fails. Use it instead of the fixed error code -ENODEV. (This driver is already doing so for nand_scan_tail().) Signed-off-by:

Since commit d1e1f4e4 ("mtd: nand: add support for reading ONFI parameters from NAND device"), the returned "type" is never used in nand_scan_ident(). Make nand_get_flash_type() simply return an integer value in order to avoid unnecessary ERR_PTR/PTR_ERR dance. Signed-off-by:

Drivers implementing ->cmd_ctrl() and relying on the default ->cmdfunc() implementation usually don't wait tCCS when a column change (RNDIN or RNDOUT) is requested. Add an option flag to ask the core to do so (note that we keep this as an opt-in to avoid breaking existing implementations), and make use of the ->data_interface information is available (otherwise, wait 500ns).

Removing CONFIG_MTD_NAND_S3C2410_HWECC option and adding a ecc_mode field in the drivers's platform data structure so it can be selectable via platform data. Also setting this field to NAND_ECC_SOFT in all boards using this driver since none of them had CONFIG_MTD_NAND_S3C2410_HWECC enabled. Signed-off-by:
