| * mtd: driver _read() returns max_bitflips; mtd_read() returns -EUCLEANPaul Burton2013-10-09-12/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linux modified the MTD driver interface in commit edbc4540 (with the same name as this commit). The effect is that calls to mtd_read will not return -EUCLEAN if the number of ECC-corrected bit errors is below a certain threshold, which defaults to the strength of the ECC. This allows -EUCLEAN to stop indicating "some bits were corrected" and begin indicating "a large number of bits were corrected, the data held in this region of flash may be lost soon". UBI makes use of this and when -EUCLEAN is returned from mtd_read it will move data to another block of flash. Without adopting this interface change UBI on U-boot attempts to move data between blocks every time a single bit is corrected using the ECC, which is a very common occurance on some devices. For some devices where bit errors are common enough, UBI can get stuck constantly moving data around because each block it attempts to use has a single bit error. This condition is hit when wear_leveling_worker attempts to move data from one PEB to another in response to an -EUCLEAN/UBI_IO_BITFLIPS error. When this happens ubi_eba_copy_leb is called to perform the data copy, and after the data is written it is read back to check its validity. If that read returns UBI_IO_BITFLIPS (in response to an MTD -EUCLEAN) then ubi_eba_copy_leb returns 1 to wear_leveling worker, which then proceeds to schedule the destination PEB for erasure. This leads to erase_worker running on the PEB, and following a successful erase wear_leveling_worker is called which begins this whole cycle all over again. The end result is that (without UBI debug output enabled) the boot appears to simply hang whilst in reality U-boot busily works away at destroying a block of the NAND flash. Debug output from this situation: UBI DBG: ensure_wear_leveling: schedule scrubbing UBI DBG: wear_leveling_worker: scrub PEB 1027 to PEB 4083 UBI DBG: ubi_io_read_vid_hdr: read VID header from PEB 1027 UBI DBG: ubi_io_read: read 4096 bytes from PEB 1027:4096 UBI DBG: ubi_eba_copy_leb: copy LEB 0:0, PEB 1027 to PEB 4083 UBI DBG: ubi_eba_copy_leb: read 1040384 bytes of data UBI DBG: ubi_io_read: read 1040384 bytes from PEB 1027:8192 UBI: fixable bit-flip detected at PEB 1027 UBI DBG: ubi_io_write_vid_hdr: write VID header to PEB 4083 UBI DBG: ubi_io_write: write 4096 bytes to PEB 4083:4096 UBI DBG: ubi_io_read_vid_hdr: read VID header from PEB 4083 UBI DBG: ubi_io_read: read 4096 bytes from PEB 4083:4096 UBI DBG: ubi_io_write: write 4096 bytes to PEB 4083:8192 UBI DBG: ubi_io_read: read 4096 bytes from PEB 4083:8192 UBI: fixable bit-flip detected at PEB 4083 UBI DBG: schedule_erase: schedule erasure of PEB 4083, EC 55, torture 0 UBI DBG: erase_worker: erase PEB 4083 EC 55 UBI DBG: sync_erase: erase PEB 4083, old EC 55 UBI DBG: do_sync_erase: erase PEB 4083 UBI DBG: sync_erase: erased PEB 4083, new EC 56 UBI DBG: ubi_io_write_ec_hdr: write EC header to PEB 4083 UBI DBG: ubi_io_write: write 4096 bytes to PEB 4083:0 UBI DBG: ensure_wear_leveling: schedule scrubbing UBI DBG: wear_leveling_worker: scrub PEB 1027 to PEB 4083 ... This patch adopts the interface change as in Linux commit edbc4540 in order to avoid such situations. Given that none of the drivers under drivers/mtd return -EUCLEAN, this should only affect those using software ECC. I have tested that it works on a board which is currently out of tree, but which I hope to be able to begin upstreaming soon.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Qspi controller can have a memory mapped port which can be used for data read. Added support to enable memory mapped port read. This patch enables the following: - It enables exchange of memory map address between mtd and qspi through the introduction of "memory_map" flag. - Add support to communicate to the driver that memory mapped transfer is to be started through introduction of new flags like "SPI_XFER_MEM_MAP" and "SPI_XFER_MEM_MAP_END". This will enable the spi controller to do memory mapped configurations if required.
