Detailed Description

struct bch_geometry - BCH geometry description. : The length of Galois Field. (e.g., 13 or 14) : A number that describes the strength of the ECC algorithm. : The size, in bytes, of a physical page, including both data and OOB. : The size, in bytes, of the metadata. : The size, in bytes, of a single ECC chunk. Note the first chunk in the page includes both data and metadata, so it's a bit larger than this value. : The number of ECC chunks in the page, : The size, in bytes, of the payload buffer. : The size, in bytes, of the auxiliary buffer. : The offset into the auxiliary buffer at which the ECC status appears. : The byte offset in the ECC-based page view at which the underlying physical block mark appears. : The bit offset into the ECC-based page view at which the underlying physical block mark appears.
