[mynewt-core] 03/07: tinyusb: Add hardware initialization for
STM32F1xx
This is an automated email from the ASF dual-hosted git repository.
jerzy pushed a commit to branch master
in repository https://gitbox.apache.org/repos/asf/mynewt-core.git
commit 4012a75cc1bc349519b50ae924de971bd7df7cdc

tinyusb: Add hardware initialization for STM32F1xx
This provides code for hardware initialization.
Part of this initialization is present in tinyusb bsps which
are not used by mynewt since it has own bsps.
