Subject: PowerPC, nand_spl: Add relocation support for -fpic
X-Git-Tag: v2011.03-rc1~55^2~9
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;ds=sidebyside;h=ee0270dff748213bd009fad566c913110fbd89f9;p=platform%2Fkernel%2Fu-boot.git

PowerPC, nand_spl: Add relocation support for -fpic

By rearranging the linker script we get support for
relocation of -fpic for free.
Move __got2_entries outside _GOT2_TABLE_ defining scope
matching the rest of PowerPC
