Linux commit a75bbe71a27 ("mtd: rawnand: fsl_ifc: fix FSL NAND driver to
 read all ONFI parameter pages")

Per ONFI specification (Rev. 4.0), if the CRC of the first parameter page
read is not valid, the host should read redundant parameter page copies.
Fix FSL NAND driver to read the two redundant copies which are mandatory
in the specification.

In case of big area read/write on spi nand, watchdog timeout may occurs.
To fix that, add WATCHDOG_RESET() in spinand_mtd_read() and
spinand_mtd_write() to ensure that watchdog is reset.

The relevant changes to the already existing GD5F1GQ4UExxG support has
been determined by consulting the GigaDevice product change notice
AN-0392-10, version 1.0 from November 30, 2020.

As the overlaps are huge, variable names have been generalized
accordingly.

Apart form the lowered ECC strength (4 instead of 8 bits per 512 bytes),
the new device ID, and the extra quad IO dummy byte, no changes had to
be taken into account.

New hardware features are not supported, namely:
 - Power on reset
 - Unique ID
 - Double transfer rate (DTR)
 - Parameter page
 - Random data quad IO

The inverted semantic of the "driver strength" register bits, defaulting
to 100% instead of 50% for the Q5 devices, got ignored as the driver has
never touched them anyway.

The no longer supported "read from cache during block erase"
functionality is not reflected as the current SPI NAND core does not
support it anyway.

Implementation has been tested on MediaTek MT7688 based GARDENA smart
Gateways using both, GigaDevice GD5F1GQ5UEYIG and GD5F1GQ4UBYIG.

* GD5F1GQ4xFxxG
* GD5F1GQ4UAYIG

<title>mtd: spi-nor-ids: Add support of flash protection to w25q128</title>

The NOR flash w25q128 denoted by JEDEC ID 0xef4018 actually represents
various models. From Winbond's website, I could only find 3 types of
them:

    W25Q128JV-IQ/JQ
    datasheet:https://www.winbond.com/resource-files/
w25q128jv%20revg%2004082019%20plus.pdf

    W25Q128FV (SPI Mode)
    datasheet: https://www.winbond.com/resource-files/
w25q128fv%20rev.m%2005132016%20kms.pdf

    W25Q128BV
    datesheet: https://www.winbond.com/resource-files/
w25q128bv_revh_100313_wo_automotive.pdf

According to the datasheets, all of these 3 types support BP(0,1,2) and
TB bits in the status register (SR), so it could reuse the flash
protection logic for ST Micro.

So it should be safe to add the SPI_NOR_HAS_LOCK and SPI_NOR_HAS_TB
flags to the w25q128 entry of spi_nor_ids table.
