commit ea1428a57662d4ae82b208113f0a8b62b6ea2aec Author: Edward O'Callaghan eocallaghan@alterapraxis.com Date: Tue Jul 29 14:09:27 2014 +1000
lenovo/t530: Use native raminit over MRC blob
We now have Native raminit for both sandy/ivybridge introduced in:
7686a56 sandy/ivybridge: Native raminit.
Let us make good use of this support over using the Intel MRC blob to initialise memory.
Remark: Note the current port is porly tested at the moment and I am the sole maintainer, however one less blob invites more interest for better support. More to come hopefuly.
