[U-Boot] u-boot.bin is so large

Hi, I have compiled the u-boot(MPC8349EMDS) successfully. but the result u-boot.bin is so large, extend 0xfe000000 If I modify the TEXT_BASE value in board/mpc8349emds/config.mk , the u-boot.bin size is changed. The u-boot code version is 1.1.6 and eldk version is 5.1 Following the instruction, I set the environment as $ source /opt/eldk-5.1/powerpc/environment-setup-* $ export CROSS_COMPILE=powerpc-linux- $ export ARCH=powerpc [hniu@host u-boot-1.1.6]$ make When I use eldk-4.2 tool chain, that is OK. and anything wrong?
