mtd: rawnand: Use the NAND framework user_conf object for ECC flags

2020-09-30T14:44:15+00:00

Instead of storing the ECC flags in chip->ecc.options, use
nanddev->ecc.user_conf.flags.

There is currently only one to save: NAND_ECC_MAXIMIZE.

mtd: rawnand: Use the ECC framework user input parsing bits

2020-09-30T14:44:15+00:00

Many helpers are generic to all NAND chips, they should not be
raw-NAND specific, so use the generic ones.

To avoid moving all the raw NAND core "history" into the generic NAND
layer, we keep a part of this parsing in the raw NAND core to ensure
backward compatibility.

mtd: rawnand: Use the ECC framework OOB layouts

2020-09-30T14:43:52+00:00

No need to have our own in the raw NAND core.

mtd: rawnand: Use the new ECC engine type enumeration

2020-09-28T13:59:42+00:00

Mechanical switch from the legacy "mode" enumeration to the new
"engine type" enumeration in drivers and board files.

The device tree parsing is also updated to return the new enumeration
from the old strings.

mtd: rawnand: Separate the ECC engine type and the ECC byte placement

2020-09-28T13:56:34+00:00

The use of "syndrome" placement should not be encoded in the ECC
engine mode/type.

Create a "placement" field in NAND chip and change all occurrences of
the NAND_ECC_HW_SYNDROME enumeration to be just NAND_ECC_HW and
possibly a placement entry like NAND_ECC_PLACEMENT_INTERLEAVED.

mtd: rawnand: Move the nand_ecc_algo enum to the generic NAND layer

2020-08-27T08:56:00+00:00

This enumeration is generic and will be reused NAND-wide.

Before moving it to the generic raw NAND core, ensure the enumeration

mtd: rawnand: Allocate the interface configurations dynamically

2020-06-26T06:35:08+00:00

Instead of manipulating the statically allocated structure and copy
timings around, allocate one at identification time and save it in the
nand_chip structure once it has been initialized.

All NAND chips using the same interface configuration during reset and
startup, we define a helper to retrieve a single reset interface
configuration object, shared across all NAND chips.

We use a second pointer to always have a reference on the currently
applied interface configuration, which may either point to the "best
interface configuration" or to the "default reset interface
configuration".

mtd: rawnand: Get rid of the default ONFI timing mode

2020-06-26T06:35:08+00:00

The ->choose_interface() hook is here for manufacturer drivers to
provide a better timing interface than the default one, this field is
not needed anymore.
