Reads from NAND devices usually trigger bitflips, this is an expected
behavior. While bitflips are under a given threshold, the MTD core
returns 0. However, when the number of corrected bitflips is above this
same threshold, -EUCLEAN is returned to inform the upper layer that this
block is slightly dying and soon the ECC engine will be overtaken so
actions should be taken to move the data out of it.
This particular condition should not be treated like an error and the
test should continue.

Introduce a new interface to instruct NAND controllers to send specific
NAND operations. The new interface takes the form of a single method
called ->exec_op(). This method is designed to replace ->cmd_ctrl(),
->cmdfunc() and ->read/write_byte/word/buf() hooks.
->exec_op() is passed a set of instructions describing the operation
to execute. Each instruction has a type (ADDR, CMD, DATA, WAITRDY)
and delay. The delay is here to help simple controllers wait enough
time between each instruction, advanced controllers with integrated
timings control can ignore these delays.
Controllers that natively support complex operations (operations
formed of several instructions) can use the NAND op parser
infrastructure. This infrastructure allows controller drivers to
describe the sequence of instructions they support (called
nand_op_pattern) and a hook for each of these supported sequences. The
core then tries to find the best match for a given NAND operation, and
calls the associated hook.
Various other helpers are also added to ease NAND controller drivers
writing.
This new interface should ease support of vendor specific operations
in that NAND manufacturer drivers now have a way to check if the
controller they are connected to supports a specific operation, and
complain or refuse to probe the NAND chip when that's not the case.

some register's offset and definition also been changed in the NAND
flash controller, this patch is the preparation to support MT7622

MT7622 NFC and ECC engine are similar to MT2701's, except below
differences:
(1)MT7622 NFC's max sector size(ECC data size) is 512 bytes, and
MT2701's is 1024, and MT7622's max sector number is 8.
(2)The parity bit of MT7622 is 13, MT2701 is 14.
(3)MT7622 ECC supports less ECC strength, max to 16 bit ecc strength.
(4)MT7622 supports less spare size per sector, max spare size per
sector is 28 bytes.
(5)Some register's offset are different, include ECC_ENCIRQ_EN,
ECC_ENCIRQ_STA, ECC_DECDONE, ECC_DECIRQ_EN and ECC_DECIRQ_STA.
(6)ENC_MODE of ECC_ENCCNFG register is moved from bit 5-6 to bit 4-5.

This driver is the last/only user of NAND_OWN_BUFFERS. Boris suggested
to remove this flag.
Taking a closer look at this driver, it calls dma_alloc_coherent() for
the concatenated area for the DMA bounce buffer + struct nand_buffers,
but the latter does not need to be DMA-coherent; cafe_{write,read}_buf
simply do memcpy() between buffers when usedma==1.
Let's do dma_alloc_coherent() for the DMA bounce buffer in the front,
and leave the nand_buffers allocation to nand_scan_tail(), then rip off
NAND_OWN_BUFFERS.
The magic number, 2112, is still mysterious (hard-coded writesize +
oobsize ?), but this is not our main interest. I am keeping it.

Right now, the chip->data_interface field is populated in
nand_scan_tail(), so after the whole NAND detection has taken place.
This is fine because these timings are not yet used by the core so
early in the probe process, but the situation is about to change with
the introduction of ->exec_op().
Also, by convention, nand_scan_ident() is not supposed to allocate
resources, only nand_scan_tail() can, so this prevent us from
allocating and initializing the data_interface object in
nand_scan_ident().
In order to solve this problem, directly embed a data_interface object
in nand_chip so that we don't have to allocate it, and initialize it to
ONFI SDR mode 0 at the very beginning of nand_scan_ident().

The core currently send the READ0 and SEQIN+PAGEPROG commands in
nand_do_read/write_ops(). This is inconsistent with
->read/write_oob[_raw]() hooks behavior which are expected to send
these commands.
There's already a flag (NAND_ECC_CUSTOM_PAGE_ACCESS) to inform the core
that a specific controller wants to send the READ/SEQIN+PAGEPROG
commands on its own, but it's an opt-in flag, and existing drivers are
unlikely to be updated to pass it.
Moreover, some controllers cannot dissociate the READ/PAGEPROG commands
from the associated data transfer and ECC engine activation, and
developers have to hack things in their ->cmdfunc() implementation to
handle such complex cases, or have to accept the perf penalty of sending
twice the same command.
To address this problem we are planning on adding a new interface which
is passed all information about a NAND operation (including the amount
of data to transfer) and replacing all calls to ->cmdfunc() to calls to
this new ->exec_op() hook. But, in order to do that, we need to have all
->cmdfunc() calls placed near their associated ->read/write_buf/byte()
calls.
Modify the core and relevant drivers to make NAND_ECC_CUSTOM_PAGE_ACCESS
the default case, and remove this flag.

Some drivers (like nand_hynix.c) call ->cmdfunc() with NAND_CMD_NONE
and a column address and expect the controller to only send address
cycles. Right now, the default ->cmdfunc() implementations provided by
the core do not filter out the command cycle in this case and forwards
the request to the controller driver through the ->cmd_ctrl() method.
The thing is, NAND controller drivers can get this wrong and send a
command cycle with a NAND_CMD_NONE opcode and since NAND_CMD_NONE is
-1, and the command field is usually casted to an u8, we end up sending
the 0xFF command which is actually a RESET operation.
Add conditions in nand_command[_lp]() functions to sending the initial
command cycle when command == NAND_CMD_NONE.
