Pull MTD updates from Miquel Raynal:
"MTD core changes:
- mtdchar: Prevent unbounded allocation in MEMWRITE ioctl
- gen_probe: Use bitmap_zalloc() when applicable
- Introduce an expert mode for forensics and debugging purposes
- Clear out unregistered devices a bit more
- Provide unique name for nvmem device
- Remove unused header file <linux/mtd/latch-addr-flash.h>
- Fixed breaking list in __mtd_del_partition.
MTD device changes:
- Warn about failure to unregister mtd device in sst25l, mchp48l640,
mchp23k256, and dataflash drivers.
Raw NAND core changes:
- Export nand_read_page_hwecc_oob_first()
GPMC memory controller for OMAP2 NAND controller changes:
- Add support for AM64 SoC and allow build on K3 platforms
- Use a compatible match table when checking for NAND controller
- Use platform_get_irq() to get the interrupt
Raw NAND controller changes:
- OMAP2 NAND controller:
- Document the missing 'rb-gpios' DT property
- Drop unused variable
- Fix force_8bit flag behaviour for DMA mode
- Move to exec_op interface
- Use platform_get_irq() to get the interrupt
- Renesas:
- Add new NAND controller driver with its bindings and MAINTAINERS entry
- Onenand:
- Remove redundant variable ooblen
- MPC5121:
- Remove unused variable in ads5121_select_chip()
- GPMI:
- Add ERR007117 protection for nfc_apply_timings
- Remove explicit default gpmi clock setting for i.MX6
- Use platform_get_irq_byname() to get the interrupt
- Remove unneeded variable
- Ingenic:
- JZ4740 needs 'oob_first' read page function
- Davinci:
- Rewrite function description

- Don't calculate ECC when reading page
SPI NOR core changes:
- Add Pratyush as SPI NOR co-maintainer.
- Flash parameters initialization was done in a spaghetti way. Clean
flash parameters initialization.
- Rework the flash_info flags and clarify where one should be used.
- Initialize all flash parameters based on JESD216 SFDP where
possible. Flash parameters and settings that are SFDP discoverable
should not be duplicated via flash_info flags at flash declaration.
- Remove debugfs entries that duplicate sysfs entries.
SPI NOR manufacturer driver changes:
- Use late_init() hook in various drivers to make it clear that those
flash parameters are either not declared in the JESD216 SFDP
standard, or the SFDP tables which define those flash parameters
are not defined by the flash.
- Fix mtd size for s3an flashes.
- Write 2 bytes when disabling Octal DTR mode: 1 byte long
transactions are not allowed in 8D-8D-8D mode.
Hyperbus changes:
- Couple of fixes in Renesas hyperbus rpc-if driver to avoid crash on
module remove and for missing check for error value in probe"

The TI's AM64 SoC has the GPMC module. Add compatible for it.
Traditionally GPMC external addresses have always been mapped to first
1GB physical address. However newer platforms, can have it mapped
at different locations. Support this address provision via device tree.

In the code: larbostd = larb->larb_gen->ostd[larb->larbid],
if "larb->larb_gen->ostd" is null, the "larbostd" is the offset(e.g.
0x80 above), it's also a valid value, then accessing "larbostd[i]" in the
"for" loop will cause the KE above. To avoid this issue, initialize
"larbostd" to NULL when the SoC doesn't have ostd setting.

The error handling code of fsl_ifc_ctrl_probe is problematic. When
fsl_ifc_ctrl_init fails or request_irq of fsl_ifc_ctrl_dev->irq fails,
it forgets to free the irq and nand_irq. Meanwhile, if request_irq of
fsl_ifc_ctrl_dev->nand_irq fails, it will still free nand_irq even if
the request_irq is not successful.
Fix this by refactoring the error handling code.
