// We create a dummy initializer in __preinit_array.YYYYY (between the standard initializers
// and the per core initializers), so we find the first per core initializer. Whilst we could
// have done this via an entry in the linker script, we want to preserve backwards compatibility
// with RP2040 custom linker scripts.
