Intel 28F128J3 is a CFI compliant flash chip.

strataflash.c driver is a pre-cursor to common cfi_flash.c. 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)

Use cfi_flash.c
