/* Use this macro to place data into Instruction RAM (IRAM)
instead of loaded into rodata which resides in DRAM.
(IRAM can also be written to as necessary.)
This may be useful to free up data RAM. However all data read from
the instruction space must be 32-bit aligned word reads
(non-aligned reads will use an interrupt routine to "fix" them and
still work, but are very slow..
