Jane Wan a75bbe71a2 mtd: rawnand: fsl_ifc: fix FSL NAND driver to read all ONFI parameter pages
Per ONFI specification (Rev. 4.0), if the CRC of the first parameter page
read is not valid, the host should read redundant parameter page copies.
Fix FSL NAND driver to read the two redundant copies which are mandatory
in the specification.

Miquel Raynal acfc33091f mtd: rawnand: fsl_ifc: fix probe function error path
An error after nand_scan_tail() should trigger a nand_cleanup().
The helper mtd_device_parse_register() returns an error code that should
be checked and nand_cleanup() called accordingly.

However, in this driver, fsl_ifc_chip_remove() which is called upon
error already triggers a nand_release() which is wrong, because a
nand_release() should be triggered only if an mtd_register() succeeded.

Move the nand_release() call out of the fsl_ifc_chip_remove() and put it
back in the *_remove() hook.

Linus Torvalds 3fd14cdcc0 MTD changes:
Core:
     * Remove support for asynchronous erase (not implemented by any of
       the existing drivers anyway)
     * Remove Cyrille from the list of SPI NOR and MTD maintainers
     * Fix kernel doc headers
     * Allow users to define the partitions parsers they want to test
       through a DT property (compatible of the partitions subnode)
     * Remove the bfin-async-flash driver (the only architecture using
       it has been removed)
     * Fix pagetest test
     * Add extra checks in mtd_erase()
     * Simplify the MTD partition creation logic and get rid of
       mtd_add_device_partitions()
 
    Drivers:
     * Add endianness information to the physmap DT binding
     * Add Eon EN29LV400A IDs to JEDEC probe logic
     * Use %*ph where appropriate
 
 SPI NOR changes:
   Drivers:
     * Make fsl-quaspi assign different names to MTD devices connected
       to the same QSPI controller
     * Remove an unneeded driver.bus assigned in the fsl-qspi driver
 
 NAND changes:
   Core:
     * Prepare arrival of the SPI NAND subsystem by implementing a
       generic (interface-agnostic) layer to ease manipulation of NAND
       devices
     * Move onenand code base to the drivers/mtd/nand/ dir
     * Rework timing mode selection
     * Provide a generic way for NAND chip drivers to flag a specific
       GET/SET FEATURE operation as supported/unsupported
     * Stop embedding ONFI/JEDEC param page in nand_chip
 
   Drivers:
     * Rework/cleanup of the mxc driver
     * Various cleanups in the vf610 driver
     * Migrate the fsmc and vf610 to ->exec_op()
     * Get rid of the pxa driver (replaced by marvell_nand)
     * Support ->setup_data_interface() in the GPMI driver
     * Fix probe error path in several drivers
     * Remove support for unused hw_syndrome mode in sunxi_nand

Miquel Raynal b958758e68 mtd: rawnand: rename SET/GET FEATURES related functions
SET/GET FEATURES are flagged ONFI-compliant because of their name. This
is not accurate as non-ONFI NAND chips support it and use it.

Rename the hooks and helpers to remove the "onfi" prefix.

Shreeya Patel 63fa37f0c5 mtd: rawnand: Replace printk() with appropriate pr_*() macro
Using pr_<loglevel>() is more concise than printk(KERN_<LOGLEVEL>).
Replace printks having a log level with the appropriate pr_*() macros.
Define pr_fmt() and remove other additional macros from the replaced
printks.
