The NAND_CMD_SET_FEATURES support is missing from denali_cmdfunc(). We also see /* TODO: Read OOB data */ comment. It would be possible to add more commands along with the current implementation, but having ->cmd_ctrl() seems a better approach from the discussion with Boris [1]. Rely on the default ->cmdfunc() from the framework and implement the driver's own ->cmd_ctrl(). This transition also fixes NAND_CMD_STATUS and NAND_CMD_PARAM handling. NAND_CMD_STATUS was just faked by the register read, so the only valid bit was the WP bit. NAND_CMD_PARAM was completely broken; not only the command sent on the bus was NAND_CMD_STATUS instead of NAND_CMD_PARAM, but also the driver was only reading 8 bytes, while the parameter page contains several hundreds of bytes. Also add ->write_byte(), which is needed for write direction commands, ->read/write_buf(16), which will be used some commits later. ->read_word() is not used for now, but the core may call it in the future. Now, this driver can drop nand_onfi_get_set_features_notsupp().
