The denali_cmdfunc() actually does nothing valuable for NAND_CMD_{PAGEPROG,READ0,SEQIN}. For NAND_CMD_{READ0,SEQIN}, it copies "page" to "denali->page", then denali_read_page(_raw) compares them just for the sanity check. (Inconsistently, this check is missing from denali_write_page(_raw).) The Denali controller is equipped with high level read/write interface, so let's skip unneeded call of cmdfunc(). If NAND_ECC_CUSTOM_PAGE_ACCESS is set, nand_write_page() will not call ->waitfunc hook. So, ->write_page(_raw) hooks should directly return -EIO on failure. The error handling of page writes will be much simpler. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Boris Brezillon <boris.brezillon@free-electrons.com>
