The __reset vector is using the 'b' instruction to jump to _PrepC. 'b' can only jump 2KB on Cortex-M0 platforms so this causes build failures when _PrepC happens to be too far away from __reset. To resolve this we use 'bl' instead as it can jump two thousand times further[0]. This can also be resolved by porting the reset vector to C or by placing the _PrepC function in a dedicated section that the linker places next to __reset.
