For Micron spi nor device, when erase/program operation fails, especially the failure results from intending to modify protected space, spi-nor upper layers still get the return which shows the operation succeeds. This is because current spi_nor_fsr_ready() only uses FSR bit.7 (flag status register) to check device whether ready. This patch fixes this issue by checking relevant error bits in FSR. The FSR is a powerful tool to investigate the status of device, checking information regarding what the memory is actually doing and detecting possible error conditions.
