| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are three reasons to add this support: 1. users probably know the interface type of their flashs, then probe can be faster if they give the right type in platform data since wrong types will not be detected. 2. sometimes, detecting can cause destory to system. For example, for kernel XIP, detecting can cause NOR enter a mode instructions can not be fetched right, which will make kernel crash. 3. For a new probe which is not listed in the rom_probe_types, if users assign it in board files, physmap can still probe it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The IRQSTAT register is a W1C register used by the interrupt handler and may have its BUSY bit changed. This makes it somewhat unreliable for the polling devready function. So switch it over to use the BUSY bit in the STAT register that always reflects the current state of the hardware. This fixes driver hangs seen when the NAND flash is under heavy system load (like I/O benchmarks).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Our write_buf/read_buf funcs always do ECC in HW ECC mode. That is not needed for raw funcs. In fact, write_buf/read_buf should be a pure func for data input/output while chip->ecc.hwctl controls ECC. Unfortunately, we can't separate ECC from normal data input/output in our NFC, so our DMA write_buf/read_buf entries are coupled with ECC operations closely. Thus we need to provide dedicated read_page_raw/write_page_raw funcs where we do non-DMA transactions so as to avoid automatic ECC.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit 18c6182bae0acca220ed6611f741034d563cd19f ("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.
