Add support for tricore TC397 1. Porting based on AURIX TC397 KIT_A2G_TC397_5V_TFT evaluation board https://www.infineon.com/cms/en/product/evaluation-boards/kit_a2g_tc397_5v_tft/ 2. In order to avoid license and coding style issues, The chip-level code still uses the implementation of AURIX Development Studio SDK. The SDK package will be downloaded as a third-party package during compilation: https://github.com/anchao/tc397_sdk 3. Single core only, SMP implementation will be provided in the future. 4. Implemented the basic System Timer, ASCLIN UART driver. 5. Only the Tasking tool chain is supported (ctc/ltc, license maybe required) 6. 'ostest' can be completed on the TC397 development board. How to run? 1. Setup the tasking toolchain and license $ export TSK_LICENSE_KEY_SW160800=d22f-7473-ff5d-1b70 $ export TSK_LICENSE_SERVER=192.168.36.12:9090 2. Build nuttx ELF $ ./tools/configure.sh tc397/nsh $ make -j ... artc I800: creating archive libc_fpu.a LD: nuttx 3. Switch to windows PC, setup AURIX-studio to Debugger Launcher 4. Replace runing ELF to nuttx, and re-download ELF Signed-off-by: chao an <anchao@lixiang.com>
