[PATCH V4 2/9] mtd: add data structures for Extended Parameter Page

[Gupta, Pekon]

> Since the ONFI 2.1, the onfi spec adds the Extended Parameter Page
> to store the ECC info.
> 
> The onfi spec tells us that if the nand chip's recommended ECC codeword
> size is not 512 bytes, then the @ecc_bits is 0xff. The host _SHOULD_
> then
> read the Extended ECC information that is part of the extended
> parameter
> page to retrieve the ECC requirements for this device.
> 
> This patch adds
>     [1] the neccessary fields for nand_onfi_params{},
>     [2] and adds the onfi_ext_ecc_info{} for Extended ECC information,
>     [3] adds onfi_ext_section{} for extended sections,
>     [4] and adds onfi_ext_param_page{} for the Extended Parameter
> Page.
