#4350 closed defect (fixed)

Infinite loop in rtems-fdt.c

The function rtems_fdt_load in file rtems-fdt.c contains an infinite loop.
The loop termination condition, size is not being decremented in the above line. Instead, the amount of bytes read is being decremented.

This bug is present in RTEMS 6 as well as 5

I have attached a patch below that fixes this.

The while loop, loops infinitely in case of raw FDT data.
The loop condition (size) is not modified during iterations.
