But cfi_flash.c doesn't work for me. It always complains "flash is busy" when I try to write something. However strata_flash.c works. why is that? By the way, is there anyway to read flash contents in u-boot? md?

Most boards are reworked to use the cfi_flash.c. To use strataflash.c you also had to define CFG_FLASH_CFI_DRIVER (as far as my memory serves). There is no reason to use a custom flash driver nowadays unless your flash is interfaced to the processor bus in a very unusual way (like data bus scrambled -- hardware design bugs) > define this macro, the compilation is ok and my flash works.
