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.
