[zhaqian12]

Add a new bootloader option of stm32f103.(UF2)

Feature Request Type

• Core functionality
• Add-on hardware support (eg. audio, RGB, OLED screen, etc.)
• Alteration (enhancement/optimization) of existing feature(s)
• New behavior

Description

Stm32duino is the default bootloader for QMK STM32F103,but because it would wait before entering the app, so its experience was not good.I found an open source bootloader project uf2-stm32f103.After testing, I think it works well so far.It takes up 16 kB of flash.So,is it necessary to add an option for this bootloader?If yes,maybe I can make a contribution.

Most likely, this would need a new ld script for the controller, and probably a new board folder, for the different config.

You can look at the blackpill uf2 support to see how to add that, I think.
