# The RP2040 sdk provides optimized compiler intrinsics which override the GCC
# built-ins. Some of these functions are located in the bootrom of the RP2040.
# Execution of these functions is realized via a vtable that is populated on
# bootup. This mechanism needs startup code and linker script support from
# ChibiOS, which is currently not implemented thus these functions are disabled
# ATM.
