QCOM NAND controller layout protects available OOB data bytes with

Following is the flow in the HW if controller tries to read erased
page:
1. First ECC uncorrectable error will be generated from ECC engine
since ECC engine first calculates the ECC with all 0xff and match
the calculated ECC with ECC code in OOB (which is again all 0xff).
2. After getting ECC error, erased CW detection logic will be
applied which is different for BCH and RS ECC
a. For BCH, HW checks if all the bytes in page are 0xff and then
it updates the status in separate register
NAND_ERASED_CW_DETECT_STATUS.
b. For RS ECC, the HW reports the same error when reading an
erased CW, but it notifies that it is an erased CW by
placing special characters at certain offsets in the
buffer.
So the erased CW detect status should be checked only if ECC engine
generated the uncorrectable error.
Currently for all other operational errors also (like TIMEOUT, MPU
errors, etc.), the erased CW detect logic is being applied so fix this
and return EIO for other operational errors.

The BAM has 3 channels - tx, rx and command. command channel
is used for register read/writes, tx channel for data writes
and rx channel for data reads. Currently, the driver assumes the
transfer completion once it gets all the command descriptors
completed. Sometimes, there is race condition between data channel
(tx/rx) and command channel completion. In these cases,
the data present in buffer is not valid during small window
between command descriptor completion and data descriptor
completion.
This patch generates NAND transfer completion when both
(Data and Command) DMA channels have completed all its DMA
descriptors. It assigns completion callback in last
DMA descriptors of that channel and wait for completion.

commit 2c8f8afa7f ("mtd: nand: add generic helpers to check,
match, maximize ECC settings") provides generic helpers which
drivers can use for setting up ECC parameters.
Since same board can have different ECC strength nand chips so
following is the logic for setting up ECC strength and ECC step
size, which can be used by most of the drivers.
1. If both ECC step size and ECC strength are already set
(usually by DT) then just check whether this setting
is supported by NAND controller.
2. If NAND_ECC_MAXIMIZE is set, then select maximum ECC strength
supported by NAND controller.
3. Otherwise, try to match the ECC step size and ECC strength closest
to the chip's requirement. If available OOB size can't fit the chip
requirement then select maximum ECC strength which can be fit with
available OOB size.
This patch introduces nand_ecc_choose_conf function which calls the
required helper functions for the above logic. The drivers can use
this single function instead of calling the 3 helper functions
individually.

The datasheet of the H27UCG8T2BTR states that this chip has a page size
of "16,384 + 1,280(Spare) bytes". The description of the "4th Byte of
Device Identifier Description" indicates that bits 6, 3 and 2 are
encoding the "Redundant Area Size / 8KB", where 640 bytes is a value of
0x6 (110 in binary notation).
hynix_nand_extract_oobsize decodes an OOB size of 640 bytes for this
chip. Kernel boot log extract before this patch:
nand: Could not find valid ONFI parameter page; aborting
nand: device found, Manufacturer ID: 0xad, Chip ID: 0xde
nand: Hynix NAND 8GiB 3,3V 8-bit
nand: 8192 MiB, MLC, erase size: 4096 KiB, page size: 16384,
OOB size: 640
However, based on the description in the datasheet we need to multiply
the OOB size with 2, because it's "640 spare bytes per 8192 bytes page
size" and this NAND chip has a page size of 16384 (= 2 * 8192). After
this patch the kernel boot log reports:

"A smaller batch for the end of the week (let's see if I can keep the
weekly cadence going for once).
All medium-grade fixes here, nothing worrisome:
- Fixes for some fairly old bugs around SD card write-protect
detection and GPIO interrupt assignments on Davinci.
- Wifi module suspend fix for Hikey.
- Minor DT tweaks to fix inaccuracies for Amlogic platforms, one
of which solves booting with third-party u-boot"

Merge tag 'for-linus-20180629' of git://git.kernel.dk/linux-block
Pull block fixes from Jens Axboe:
"Small set of fixes for this series. Mostly just minor fixes, the only
oddball in here is the sg change.
The sg change came out of the stall fix for NVMe, where we added a
mempool and limited us to a single page allocation. CONFIG_SG_DEBUG
sort-of ruins that, since we'd need to account for that. That's
actually a generic problem, since lots of drivers need to allocate SG
lists. So this just removes support for CONFIG_SG_DEBUG, which I added
back in 2007 and to my knowledge it was never useful.
Anyway, outside of that, this pull contains:
- clone of request with special payload fix (Bart)
- drbd discard handling fix (Bart)
- SATA blk-mq stall fix (me)
- chunk size fix (Keith)
- double free nvme rdma fix (Sagi)"
* tag 'for-linus-20180629' of git://git.kernel.dk/linux-block:
sg: remove ->sg_magic member
drbd: Fix drbd_request_prepare() discard handling
blk-mq: don't queue more if we get a busy return
block: Fix cloning of requests with a special payload
nvme-rdma: fix possible double free of controller async event buffer
block: Fix transfer when chunk sectors exceeds max
Two regression fixes, and a new syscall wire-up.
A fix for the recent conversion to time64_t in the powermac RTC routines, which
caused time to go backward.
Another fix for fallout from the split PMD PTL conversion.
Wire up the new io_pgetevents() syscall.
