Thanks for the steps.
Actually I was following the same but I get an error " Failed to load boot loader stage 2 (BL2) firmware", although I have
placed the 'bl2.bin' at the same directory level as the ARMv8 foundation model (v2 - Release 52rel06).

The complete boot log is:

Escape character is '^]'.
Booting trusted firmware boot loader stage 1
Built : 16:09:23, Feb 11 2014
ERROR: Cannot access 'bl2.bin' file (-1).
Failed to load boot loader stage 2 (BL2) firmware.

Did you see some similar issues at your end?
