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
