rt-thread packages update后下载了CMSISI-latest 发现SConsript脚本中

```c
if GetDepend('PKG_CMSIS_CORE'):
    CPPPATH = CPPPATH + [cwd + '/CMSIS_5/CMSIS/Core/Include']

if GetDepend('PKG_CMSIS_NN'):
    CPPPATH = CPPPATH + [cwd + '/CMSIS_5/CMSIS/NN/Include']

nn_activation_src = Glob('CMSIS_5/CMSIS/NN/Source/ActivationFunctions/*.c')
    nn_convolution_src = Glob('CMSIS_5/CMSIS/NN/Source/ConvolutionFunctions/*.c')
    nn_fully_connected_src = Glob('CMSIS_5/CMSIS/NN/Source/FullyConnectedFunctions/*.c')
    nn_support_src = Glob('CMSIS_5/CMSIS/NN/Source/NNSupportFunctions/*.c')
    nn_pooling_src = Glob('CMSIS_5/CMSIS/NN/Source/PoolingFunctions/*.c')
    nn_softmax_src = Glob('CMSIS_5/CMSIS/NN/Source/SoftmaxFunctions/*.c')

if GetDepend('PKG_CMSIS_NN_ACTIVATION'):
        src += nn_activation_src
    if GetDepend('PKG_CMSIS_NN_CONVOLUTION'):

        src += nn_pooling_src
    if GetDepend('PKG_CMSIS_NN_SOFTMAX'):
        src += nn_softmax_src

if GetDepend('PKG_CMSIS_RTOS2'):
    CPPPATH = CPPPATH + [cwd + '/CMSIS_5/CMSIS/RTOS2/Include',cwd + '/RTOS2/RT-Thread/src']
    src = src + Glob('RTOS2/RT-Thread/src/*.c')

# Definitions for MATH
if GetDepend('ARCH_ARM_CORTEX_M7'):
    CPPDEFINES += ['ARM_MATH_CM7']
elif GetDepend('ARCH_ARM_CORTEX_M4'):
    CPPDEFINES += ['ARM_MATH_CM4']
elif GetDepend('ARCH_ARM_CORTEX_M3'):
    CPPDEFINES += ['ARM_MATH_CM3']

```

只有CORE，NN的配置选项，并且没有cortex-a7配置，请教一下如何实现开启DSP选项，因为要测试FFT能力。
是不是cortex'-a7需要开启Core_A?是不是必须手动修改该脚本实现了？
