Hi,all,
    I'm porting u-boot-1.1.4 to (Embedded Planet)EP405 (with ppc405GPr
processor), As Denk suggested, the esd CPCI4052 board is most similiar
to my board. however CPCI4052 has FPGA configuration while my board
doesn't have FPGA, so, if i don't consider this difference during the
porting procedure because of its complexity, will the u-boot work
well? Because i can't debug u-boot now
    Thanks and best wishes

I never made such a suggestion.

Of course it cannot work if you try to access a non-existing FPGA.

Porting U-Boot is a complex  task,  and  this  complexity  cannot  be
ignored. At least not without consequences ;-)

Thant was me. IIRC because of the onboard SDRAM setup.

You have to remove all FPGA replated code in your board port.
