Not only powerpc/mpc85xx but also Freescale Layerscape platforms will use fdt_fixup_fman_firmware() to insert Fman ucode blob into the device tree. So move the function to Fman driver code.
Signed-off-by: Gong Qianyu Qianyu.Gong@nxp.com --- V5: - Move the function changes to a separate patch. V4: - No change. V3: - Remove file changes about "qe.h". (Should be put in the first patch of this patchset) V2: - New patch.
