e260efea80 mtd: rawnand: qcom: Early structure initialization
Instead of allocating a structure on the stack with random data and then
expect the callee to perform the initialization (which is, in general,
error prone), prefer zeroing the structure explicitly at allocation and
provide the already zeroed area, so no explicit memset operation is
needed. It is probably safer to do so, so we limit the timeframe when
dirty data could actually be accessed by mistake.

60177390fa mtd: rawnand: brcmnand: Fix mtd oobsize
brcmnand controller can only access the flash spare area up to certain
bytes based on the ECC level. It can be less than the actual flash spare
area size. For example, for many NAND chip supporting ECC BCH-8, it has
226 bytes spare area. But controller can only uses 218 bytes. So brcmand
driver overrides the mtd oobsize with the controller's accessible spare
area size. When the nand base driver utilizes the nand_device object, it
resets the oobsize back to the actual flash spare aprea size from
nand_memory_organization structure and controller may not able to access
all the oob area as mtd advises.

This change fixes the issue by overriding the oobsize in the
nand_memory_organization structure to the controller's accessible spare
area size.

c17a90a46a mtd: rawnand: meson: waiting w/o wired ready/busy pin
If there is no wired ready/busy pin, classic way to wait for command
completion is to use function 'nand_soft_waitrdy()'. Meson NAND has
special command which allows to wait for NAND_STATUS_READY bit without
reading status in a software loop (as 'nand_soft_waitrdy()' does). To
use it send this command along with NAND_CMD_STATUS, then wait for an
interrupt, and after interrupt send NAND_CMD_READ0. So this feature
allows to use interrupt driven waiting without wired ready/busy pin.

This reverts commit fc9e18f9e987ad46722dad53adab1c12148c213c.

This patch was a work around to fix timeout issue while operating in NVDDR
mode with software ECC engine. This patch prevents the Arasan NAND driver
from operating in NVDDR mode with software ECC engine resulting in a
significant performance degradation with SW-ECC.
'commit 7499bfeedb47 ("mtd: rawnand: arasan: Update NAND bus clock instead
of system clock")' and 'commit e16eceea863b ("mtd: rawnand: arasan: Fix
clock rate in NV-DDR")'
fixes the timeout issue in NVDDR mode with SW-ECC so, reverting the changes
as this work around is no longer required.

c4d28e30a8 mtd: rawnand: marvell: don't set the NAND frequency select
marvell_nfc_setup_interface() uses the frequency retrieved from the
clock associated with the nand interface to determine the timings that
will be used. By changing the NAND frequency select without reflecting
this in the clock configuration this means that the timings calculated
don't correctly meet the requirements of the NAND chip. This hasn't been
an issue up to now because of a different bug that was stopping the
timings being updated after they were initially set.
