    Subject[PATCH v5 03/12] mtd: pxa3xx_nand: add a default chunk size
    Date
    When keeping the configuration set by the bootloader (by using
    the marvell,nand-keep-config property), the pxa3xx_nand_detect_config()
    function is called and set the chunk size to 512 as a default value if
    NDCR_PAGE_SZ is not set.

    In the other case, when not keeping the bootloader configuration, no
    chunk size is set. Fix this by adding a default chunk size of 512.
