+Subject: [PATCH v2 446/447] mtd: spinand: gigadevice: Add QE Bit
+
+The following GigaDevice chips have the QE BIT in the feature flags, I
+checked the datasheets, but did not try this.
+* GD5F1GQ4xExxG
+* GD5F1GQ4xFxxG
+* GD5F1GQ4UAYIG
+* GD5F4GQ4UAYIG
+
+The Quad operations like 0xEB mention that the QE bit has to be set.

+Subject: [PATCH v2 447/447] mtd: spinand: gigadevice: Add support for
+ GD5F4GQ4xC
+
+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.
