This series ports ESMT NAND support from Linux. Since both ESMT and Gigadevice use the same manufacturer ID, core part of SPI NAND framework should be updated as well to allow for such chips detection. Currently all detect() ops return an error code when chip's manufacturer ID matches, but device ID does not. This forces spinand_manufacturer_detect function to stop and report an error. Porting a rework from Linux allows us to fix this issue and keep u-boot and kernel in sync.
