2025-04-09alif/mpmetalport: Only notify after metal subsystem is init'd.Damien George
Signed-off-by: Damien George <damien@micropython.org>
2025-04-09alif: Link with libnosys.iabdalkader
This allows the correct start up functions to be called by the stdlib. Signed-off-by: iabdalkader <i.abdalkader@gmail.com>
2025-04-09alif/mpmetalport: Use MHU to notify remote cores.iabdalkader
Unlike HWSEM, the MHU IRQ can wake up cores from low-power modes, making it better suited for notifying remote cores. Note that no special function is required to wake up a remote core—the act of sending a message alone will notify it. Signed-off-by: iabdalkader <i.abdalkader@gmail.com>
2025-04-09alif/se_services: Add a secondary MHU channel.iabdalkader
This channel can be used to communicate (pass messages) between the M55 cores in the RTSS. Currently it's only used to notify the cores. Signed-off-by: iabdalkader <i.abdalkader@gmail.com>

2025-04-09alif/modmachine: Implement proper low-power modes.iabdalkader
Lightsleep current is around 23mA. Deepsleep current is sub 50uA. Signed-off-by: iabdalkader <i.abdalkader@gmail.com>
2025-04-09alif/se_services: Use EUI extension for unique id.iabdalkader
The right service call to get UID is SERVICES_system_get_eui_extension which returns an 8 bytes UID. Signed-off-by: iabdalkader <i.abdalkader@gmail.com>
2025-04-09alif/ospi_flash: Add 16-bit words swap flash setting.iabdalkader
The byte order (endianness) seems to be swapped when read in 8D-8D-8D in XIP mode, for most flashes, with the exception of MX which seems to swap half-words. This commit adds a flash setting to allow parts to enable half-word swap when data is written, to fix this issue. By default, only endianness is fixed. Tested with both MX and ISSI parts on AE3, flash test and simple file write/read. Signed-off-by: iabdalkader <i.abdalkader@gmail.com>
2025-04-09alif/ospi_flash: Use OSPI in XIP mode only.iabdalkader
The OSPI controller supports concurrent direct/XIP accesses, there's no need to disable XIP on direct access. In addition to improving the performance, this change lays the groundwork for supporting access by the HP and HE cores simultaneously. Signed-off-by: iabdalkader <i.abdalkader@gmail.com>
2025-04-09alif/ospi_ext: Optimize XIP speed.iabdalkader
This change increases XIP read speed to ~30Mbytes/s at 50MHz DDR: - Enable continuous mode. - Remove hard-coded settings. - Set XIP continuous mode timeout. The prefetch remains disabled. Although enabling the prefetch gives the best performance for the CPU in XIP mode, it must be disabled when the NPU accesses the OSPI flash. Signed-off-by: iabdalkader <i.abdalkader@gmail.com>
2025-04-09alif/ospi_flash: Enable pull-up IO2/WP.iabdalkader
Leaving this pin low in combination with the default EM settings enables flash protection for the EM flash. Signed-off-by: iabdalkader <i.abdalkader@gmail.com>
2025-04-09alif/ospi_flash: Add negative clock pin.iabdalkader
Signed-off-by: iabdalkader <i.abdalkader@gmail.com>
2025-04-09alif/ospi_flash: Configure dummy cycles.iabdalkader
The default dummy cycles may not match the actual flash frequency supported by a certain board. For example, the MX chip uses 20 dummy cycles by default which supports up to 200MHz DDR, but the maximum frequency supported by the AE3 board is 50MHz DDR. So the dummy cycles for this board can be as low as 6. It's important to set the correct dummy cycles, as it results in doubling the XIP read speed, in the case of the AE3 board.

2025-04-09alif/ospi_flash: Support flash device auto-detection in runtime.iabdalkader
This commit enables detecting the flash device in runtime, and uses the settings of the detected device instead of board-defined flash settings. Signed-off-by: iabdalkader <i.abdalkader@gmail.com>

2025-04-09alif: Add initial port to Alif Ensemble MCUs.Damien George
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>
