Relocated suspend code in OCRAM lacks compiler-generated CFI type signatures. When CONFIG_CFI=y is active, the indirect call to imx6_suspend_in_ocram_fn triggers a strict CFI violation panic.
Would it be possible to just copy the 4-byte CFI hash prefix to OCRAM when relocating the function? If not, the __nocfi approach seems reasonable to me. Sami
