[mynewt-core] 02/03: hw/mcu/nrf52: Add common startup code

This is an automated email from the ASF dual-hosted git repository.

andk pushed a commit to branch master
in repository https://gitbox.apache.org/repos/asf/mynewt-core.git

commit 9d7256d0f53dada0790a8ded465729e6f896375d
Author: Andrzej Kaczmarek <an...@codecoup.pl>
AuthorDate: Thu Feb 24 21:57:07 2022 +0100

    hw/mcu/nrf52: Add common startup code
    
    This adds common startup code to nRF52 package so it can be reused by
    BSP. This avoids multiple duplicates of the same file in all BSPs.
    
    Also proper configuration is added so standard and split startup code
    is not included in build at the same time. This fixes issue when link
    option -whole-archive is used.
