* pinout yamls removed
* machine: implement default UART pin configuration for Embedfire boards
* flash command moved to chip level so VS Code plugin can select bare chip
* machine: add support for alternate pin mode configuration
* add build targets for embedfire on py32
* add support for embedfire target in GNUmakefile for py32
* lib/py32-svd: remove duplicate DBGMCU.IDCODE CODE field
Update submodule to fix duplicate SetIDCODE/GetIDCODE method
declarations in the generated py32f002bxx.go device file.
* update subproject commit reference in py32-svd
* refactor: update CPU frequency handling in machine and runtime packages
* refactor: replace ConfigureUARTPin function with direct pin configuration in UART setup
* SetAltFunc documentation for GPIO pin alternate functions
* refactor: improve UART write and flush error handling with timeout
* machine/py32: generalize UART driver to any USART
Add a per-instance setup func to the UART type so the driver is no longer
hardwired to USART1. DefaultUART stays USART1; add UART2 (USART2) in a
separately build-tagged file since py32f002x parts lack USART2. RX IRQ
handlers reference runtime-assigned vars to break the init cycle, and setup
is assigned in the var initializer so it runs before InitSerial.
Add the py32f003_32k_4k target (32K flash / 4K RAM).
* Add canonical PY32F002, F003, and F030 density targets
Use CMSIS/pyocd device names for target files and build tags. Add all F003 and F030 densities plus F002A/B, correct F002B to 24K flash and its own startup file, fix the F030x8 pyocd target, and update Embedfire inheritance.
