2020-11-20mtd: rawnand: socrates: Move the ECC initialization to ->attach_chip()Miquel Raynal
The probe function is only supposed to initialize the controller hardware but not the ECC engine. Indeed, we don't know anything about the NAND chip(s) at this stage. Let's move the logic initializing the ECC engine, even pretty simple, to the ->attach_chip() hook which gets called during nand_scan() routine, after the NAND chip discovery. As the previously mentioned logic is supposed to parse the DT for us, it is likely that the chip->ecc.* entries be overwritten. So let's avoid this by moving these lines to ->attach_chip().

2020-10-26mtd: rawnand: ifc: Move the ECC engine initialization to the right placeFabio Estevam
No ECC initialization should happen during the host controller probe. In fact, we need the probe function to call nand_scan() in order to: - identify the device, its capabilities and constraints (nand_scan_ident()) - configure the ECC engine accordingly (->attach_chip()) - scan its content and prepare the core (nand_scan_tail()) Moving these lines to fsl_ifc_attach_chip() fixes a regression caused by a previous commit supposed to clarify these steps.

2020-09-30mtd: spinand: gigadevice: Add support for GD5F4GQ4xCHauke Mehrtens
This adds support for the following 4GiB chips: GD5F4GQ4RCYIG 1.8V GD5F4GQ4UCYIG 3.3V The datasheet can be found here: https://www.novitronic.ch/sixcms/media.php/2/DS-00173-GD5F4GQ4xCxIG-Rev1.574695.pdf The GD5F4GQ4UCYIGT (3.3V) version is used on the Imagination Technologies Creator Ci40 (Marduk), the 1.8V version was not tested. This device only works in single SPI mode and not in dual or quad mode for me on this board.
