From 664c869f7749da96bbea7307beb043dfe52593c5 Mon Sep 17 00:00:00 2001 From: Kevin O'Connor Date: Sun, 28 Jul 2019 23:23:18 -0400 Subject: lib: Remove unused stm32f1 "hal" code Now that the stm32f1 code has been merged into the stm32 code, there is no longer a need to use the upstream stm32f1 "hal" code.
