This commit adds the beginning of a new alif port with support for Alif Ensemble MCUs. See https://alifsemi.com/ Supported features of this port added by this commit: - UART REPL. - TinyUSB support, for REPL and MSC. - Octal SPI flash support, for filesystem. - machine.Pin support. General notes about the port: - It uses make, similar to other bare-metal ports here. - The toolchain is the standard arm-none-eabi- toolchain. - Flashing a board can be done using either the built-in serial bootloader, or JLink (both supported here). - There are two required submodules (one for drivers/SDK, one for security tools), both of which are open source and on GitHub. - No special hardware or software is needed for development, just a board connected over USB. OpenMV have generously sponsored the development of this port. Signed-off-by: Damien George <damien@micropython.org> Signed-off-by: iabdalkader <i.abdalkader@gmail.com>
