of having them loaded into rodata (which resides in DRAM)
Unlike the ESP8266 SDK you don't need an attribute like this for
standard functions. They're stored in flash by default. But
variables need them.
Important to note: IROM flash can only be accessed via 32-bit word
aligned reads. It's up to the user of this attribute to ensure this.
