Subject: powerpc/85xx: fix NAND boot linker scripts for -fpic
X-Git-Tag: v2012.07-rc1~142^2~5
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=d2a97daf629a49a416ed405b8c7c2a1e77b99148;p=oweals%2Fu-boot.git

powerpc/85xx: fix NAND boot linker scripts for -fpic

GOT is now handled the way the main u-boot.lds does it.  Without this,
the boot hangs when built with newer GCC (since 4.6).  Older toolchains
hid the issue by converting -fpic to -fPIC.
