If the OOB size is not multiple of the cache line size, the ARMv7 cache operation still prints "Misaligned operation at range". => nand info Device 0: nand0, sector size 256 KiB Page size 4096 b OOB size 224 b Erase size 262144 b subpagesize 4096 b options 0x00104200 bbt options 0x00060000 => nand dump 0 CACHE: Misaligned operation at range [9fb15280, 9fb16360] CACHE: Misaligned operation at range [9fb15280, 9fb16360] CACHE: Misaligned operation at range [9fb15280, 9fb16360] CACHE: Misaligned operation at range [9fb15280, 9fb16360] ... The cache flushing operations won't happen in this case to cover all of the range to fix this by making sure we have things aligned.

This is a fix made for the fsl_ifc_nand driver on linux kernel by Pavel Machek and is applied to uboot. It is currently on applied on linux-mtd. https://patchwork.kernel.org/patch/9758117/ IFC always raises ECC errors on erased pages. It is only ignored when the buffer is checked for all 0xFF by is_blank(). The problem is a single bitflip will cause is_blank() and then mtd_read to fail. The fix makes use of nand_check_erased_ecc_chunk() to check for empty pages instead of is_blank(). This also makes sure that reads are made at ECC page size granularity to get a proper bitflip count. If the number of bitflips does not exceed the ECC strength, the page is considered empty and the bitflips will be corrected when data is sent to the higher layers (e.g. ubi).

The NAND framework makes sure to pass in the buffer with at least chip->buf_align alignment. Currently, the Denali NAND driver only requests 16 byte alignment. This causes unaligned cache operations for the DMA transfer.
