[PATCH v1 0/2] mtd: spinand: add support for ESMT F50x1G41LB

[Igor Prusov]

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.
