[U-Boot] (no subject)

[HeLei]

Hi, all
Does u-boot supports ONFI (open nand flash interface)? In my opinion, u-boot doesn't support ONFI,  though it is also a general framework for nand flash.
Following are the reasons I can figure out:(1) Not all mandatory commands are supported. e.g. "Read Parameter Page".  Furthermore Maybe some command code is different from ONFI spec.(2) The coding mechanism is not general enough. It maintains a table "nand_flash_ids" and "nand_manuf_ids", if some flash exists in the table, than it can be supported. To support more type of flash, the table has to be extended. If ONFI supported, than all information associated shall be read out from flash, other than from source code files.
If I'm not right, please let me know.ThanksLeon
