[U-Boot-Users] still error: Not enough room for program headers

I'm porting u-boot to EP405 as i said in last letter, and i have made some changes in ../include/configs/ep405.h(changed from cpci4052.h ) mainly on Flash and also on other files to make them suitful(i think) with my board . Then follows compile,but atfter "make all" ,there is still an error as follow: ppc_4xx-ld: u-boot: Not enough room for program headers (allocated 2, need 3) ppc_4xx-ld: final link failed: Bad value

Would you please tell me what's the problem on earth and how to solve it? Thank you in advace !
