/* Use this macro to store constant values in IROM flash instead

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.
