- * - cmd_ctrl: hardwarespecific function for accesing control-lines
- * - dev_ready: hardwarespecific function for  accesing device ready/busy line
- * - enable_hwecc?: function to enable (reset)  hardware ecc generator. Must

- * - ecc.mode: mode of ecc, see defines
- * - chip_delay: chip dependent delay for transfering data from array to
- *   read regs (tR)
- * - options: various chip options. They can partly be set to inform
- *   nand_scan about special functionality. See the defines for further
- *   explanation
- * Members with a "?" were not set in the merged testing-NAND branch,
