Subject: Official ARM version: v5.4.0

    Add CMSIS V5.4.0, please refer to index.html available under \docs folder.

    Note: content of \CMSIS\Core\Include has been copied under \Include to keep the same structure
         used in existing projects, and thus avoid projects mass update
    Note: the following components have been removed from ARM original delivery (as not used in ST packages)
        - CMSIS_EW2018.pdf
        - .gitattributes
        - .gitignore
        - \Device
        - \CMSIS
           - \CoreValidation
		   - \DAP
           - \Documentation
           - \DoxyGen
           - \Driver
           - \Pack
           - \RTOS\CMSIS_RTOS_Tutorial.pdf
           - \RTOS\RTX
           - \RTOS\Template
           - \RTOS2\RTX
           - \Utilities
           - All ARM/GCC projects files are deleted from \DSP, \RTOS and \RTOS2
