For powerpc SoCs (including mpc85xx, mpc86xx), global data is used for initializing LAWs, before calling function baord_inti_f(). This data should not be cleared later.
Signed-off-by: York Sun yorksun@freescale.com --- Change log v2: Instead of adding back gd init for all PPC, preserve gd for mpc85xx and mpc86xx.
Note, need other maintainers to fix 83xx, 5xxx, 512x as I don't have boards to verify.
