[mynewt-core] 03/06: stm32: Add call to _sbrkInit to startup files
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 e1da7a4b032756551efb745624c1a56a202121cd

stm32: Add call to _sbrkInit to startup files
Previously STM32 based BSP provided own version of _sbrk
that relayed on __HeabBase, __HeapLimit symbols provided by
linker.
BSP for other mcus has explicit call to _sbrkInit in startup
files.
This makes STM32 startup files look more like most other startup
files.
Also common stm32 sbrk.c file is dropped in favor of one that is in
hal.
