From 125e2bc1f24736291e752d78a769f7f942050be2 Mon Sep 17 00:00:00 2001 From: "J. German Rivera" Date: Fri, 20 Mar 2015 19:28:18 -0700 Subject: 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.
