How to porting u-boot to my own board?

Hi Scott,

I search the files related with flash in u-boot directory and find some

> ..\u-boot\common\cmd_flash.c

> ..\u-boot\common\env_dataflash.c

> ..\u-boot\common\env_flash.c

> ..\u-boot\common\flash.c

> ..\u-boot\drivers\cfi_flash.c

> ..\u-boot\include\flash.h

> ..\u-boot\include\dataflash.h

> ..\u-boot\board\altera\common\flash.c

> ..\u-boot\board\altera\dk1c20\flash.c

> ..\u-boot\board\altera\common\AMDLV065D.c

> ..\u-boot\board\psyent\common\AMDLV065D.c

> .. and the cfi_flash.c you send to me

I have found that all *.c files are based on flash.h, what the relationship between these files?

I know the function below, they are flash driver for u-boot.

> ..\u-boot\board\altera\common\AMDLV065D.c

> ..\u-boot\board\psyent\common\AMDLV065D.c

But, the files below play what function. Do they have relation with u-boot flash driver?

> ..\u-boot\common\cmd_flash.c

> ..\u-boot\common\env_dataflash.c

> ..\u-boot\common\env_flash.c

> ..\u-boot\common\flash.c

> ..\u-boot\drivers\cfi_flash.c

Thanks,
