>> This patch series intends to solve various problems.
>>
>> [1] The driver just retrieves the OOB area as-is
>>     whereas the controller uses syndrome page layout.
>> [2] Many NAND chip specific parameters are hard-coded in the driver.
>> [3] ONFi devices are not working
>> [4] It can not read Bad Block Marker
>>
>> Outstanding changes are:
>> - Fix raw/oob callbacks for syndrome page layout
>> - Implement setup_data_interface() callback
>> - Fix/implement more commands for ONFi devices
>> - Allow to skip the driver internal bounce buffer
>> - Support PIO in case DMA is not supported
>> - Switch from ->cmdfunc over to ->cmd_ctrl

BTW, this series can not apply to Boris's tree
because of the following commit.

    mtd: nand: Make sure drivers not supporting SET/GET_FEATURES
return -ENOTSUPP



I will send v6 rebased on nand/next branch.
