CMSIS-DSP: Customization of FFT tables.
...
Compilation symbols have been introduced to allow to include only the
FFT tables which are useful in a given application.
The README.md in DSP is giving more details.

CMSIS DSP : Added a cmake build system
...
It is not replacing the current MDK and ArmDS projects.
It is a complementary way to build CMSIS-DSP.
Current version is supporting ARM AC6 compiler from ArmDS.
The result of the build can be run on a FVP for instance.
It could be extended to use different toolchain and build for different
targets.
The README.md in DSP folder is giving all the details.

Implement arm_rfft_fast_init_f32 with new separate initialize functions.

Split rfft_fast_init_f32 into separate initializer functions.
...
The rationale here is that if the caller knows the size FFT they require
at compile time, only the look-up tables required for that size are
placed in the data segment (ROM). This saves between ~40k to ~80k of
ROM when only using a single FFT size.
