[16/50] [abbrv] incubator-mynewt-core git commit: MYNEWT-475: BSP
Cleanup
MYNEWT-475: BSP Cleanup
Modification of nrf linker scripts. The linker scripts are now split
apart into part variation specific linker scripts for images and
the bootloader. Common linker scripts are now located in the
mcu directories. The bsp.yml files now specify the two split
scripts. Users can still override these the default scripts
with specific ones using the bsp.yml file.
