    MLK-15286 arm: arm64: only use general regs · 186ccd8d
    Peng Fan authored
    When compiling with android toolchain, there is an instruction
    "str     q0, [x8],#16", but x8 is not 16bytes aligned,
    this instruction will trigger sync abort.
    
    So, following Linux kernel, only use general regs for arm64.
    If not, compiler may use simd registers Q[x]. We need to avoid
    using simd registers in U-Boot, because load/store Q[x] has
    restriction that 128bits aligned when str/ldr.
