* Extract all poll/threadsafe_background/freertos from cyw43_arch into new abstraction async_context: * provides support for asynchronous events (timers/IRQ notifications) to be handled in a safe context. * now guarantees all callbacks happen on a single core. * is reusable by multiple different libraries (stdio_usb can now be ported to this but hasn't been yet). * supports multiple independent instances (independent instances will not block each other). * cyw43_arch libraries cleaned up to use the new abstraction. Note each distinct cyw43_arch type is now a very thin layer that creates the right type of context and adds cyw43_driver and lwip support as appropriate. Additionally, * Add new pico_time and hardware_alarm APIs * Add from_us_since_boot() * Add alarm_pool_create_with_unused_hardware_alarm() * Add alarm_pool_add_alarm_at_force_in_context() * Add hardware_alarm_claim_unused() * Add hardware_alarm_force_irq() * Added panic_compact() and some minor comment cleanup; moved FIRST_USER_IRQ define to platform_defs.h |
