Its often used in small deeply embedded systems. Microcontrollers,
rather than something which can run Linux.

Ah, all inside a header file. Probably why i missed it. But ihex is
not SREC. ihex came from Intel. SREC from Motorola.
So i would follow the basic flow in include/linux/ihex.h, add an
include/linux/srec.h but adapt it for SREC.
