drivers/fsl-mc: Changed MC firmware loading for new boot architecture
Changed MC firmware loading to comply with the new MC boot architecture. Flush D-cache hierarchy after loading MC images. Add environment variables "mcboottimeout" for MC boot timeout in milliseconds, "mcmemsize" for MC DRAM block size. Check MC boot status before calling flib functions. Signed-off-by: J.
