Merge pull request #15422 from mipsopen-fwu:msa-dev * Added MSA implementations for mips platforms. Intrinsics for MSA and build scripts for MIPS platforms are added. Signed-off-by: Fei Wu <fwu@wavecomp.com> * Removed some unused code in mips.toolchain.cmake. Signed-off-by: Fei Wu <fwu@wavecomp.com> * Added comments for mips toolchain configuration and disabled compiling warnings for libpng. Signed-off-by: Fei Wu <fwu@wavecomp.com> * Fixed the build error of unsupported opcode 'pause' when mips isa_rev is less than 2. Signed-off-by: Fei Wu <fwu@wavecomp.com> * 1. Removed FP16 related item in MSA option defines in OpenCVCompilerOptimizations.cmake. 2. Use CV_CPU_COMPILE_MSA instead of __mips_msa for MSA feature check in cv_cpu_dispatch.h. 3. Removed hasSIMD128() in intrin_msa.hpp. 4. Define CPU_MSA as 150. Signed-off-by: Fei Wu <fwu@wavecomp.com> * 1. Removed unnecessary CV_SIMD128_64F guarding in intrin_msa.hpp. 2. Removed unnecessary CV_MSA related code block in dotProd_8u(). Signed-off-by: Fei Wu <fwu@wavecomp.com> * 1. Defined CPU_MSA_FLAGS_ON as "-mmsa". 2. Removed CV_SIMD128_64F guardings in intrin_msa.hpp. Signed-off-by: Fei Wu <fwu@wavecomp.com> * Removed unused msa_mlal_u16() and msa_mlal_s16 from msa_macros.h.

# MIPS ToolChanin can be downloaded from https://www.mips.com/develop/tools/codescape-mips-sdk/ .
# Toolchains with 'mti' in the name (and install directory) are for MIPS R2-R5 instruction sets.
# Toolchains with 'img' in the name are for MIPS R6 instruction sets.
# It is recommended to use cmake-gui for build scripts configuration and generation:
# 1. Run cmake-gui
# 2. Specifiy toolchain file mips32r5el-gnu.toolchian.cmake for cross-compiling.
# 3. Configure and Generate makefiles.
# 4. make -j4 & make install
