Hi All,

Hope everyone is doing great:)

I am trying to build U-boot:2013-04.But running into this error:
mips64-nlm-elf-ld: arch/mips/cpu/mips64/start.o: relocation (null) against
`board_init_f' can not be used when making a shared object; recompile with
-fPIC
arch/mips/cpu/mips64/start.o: could not read symbols: Bad value.


Initially,In file arch/mips/config.mk,I commented the flag:
#LDFLAGS_FINAL                   +=  -pie
This error resolved.But after relocation of u-boot code,we need this
flag.So i need to uncomment this flag.and again i am running into this
error agian.

Anyone faced this issue earlier.Anyone please provide pointers to resolve
this.

Thanks in advance!!

Regards,
Krishna
