Thanks for the correction, Patrice.

I came back to spi-nor-ids.c, there are two places in the code checking
CONFIG_SPI_FLASH_STMICRO define, at line 167 (a lot of Micron flashes
included in the block), and at line 239, furthermore, there is no
SPI_FLASH_MICRON config menu in Kconfig file. I got confused, why 
SPI_FLASH_MICRON is not in Kconfig?
