Dear Chunhe Lan,

As you state yourself, your modification has the negative impact of increasing the image size. What would be the benefits of it?
Are you trying to fix any specific problem? Which one? I am not aware of any related isses for any of the mainline PowerPC systems...
Yes, I have fixed the booting issue of nand u-boot ofP1010/P1022/P1023/P2020 with this patch.
What exactly is "the booting issue" you mention here? Are you referring to any messages previously posted here? Which?
But when use gcc 4.6 version, produce the size of u-boot-nand.bin tobe different with -fpic or -fPIC. The some GOT entries of u-boot-nand.bin are lost with -fpic(because limit the size), so u-boot-nand.bin hangs when booting. But use -fPIC, the u-boot-nand.bin is OK.
What do you mean "GOT entries ... are lost"? Are there any error messages?
If yes, what exactly are these?
If not, then this has to be considered a serious bug in either the compiler and the linker, and it should be fixed there rather than being papered over.
Best regards,
Wolfgang Denk
