Since commit 18c6182b ("Rework probing/JEDEC code"), m25p80 driver successfully registers chips even if JEDEC probing fails. This was needed to support non-JEDEC flashes. Though, it appears that some platforms (e.g. blackfin bf533 stamp[1]) used the old behavior to detect if there's any flash connected, so the driver have to fail on JEDEC probing errors. This patch restores the old behavior for JEDEC flashes, and adds "-nonjedec" SPI device IDs for M25Pxx flashes, so that the kernel still supports non-JEDEC flashes.
