From c0cbd6e8c2bad5453f7c3b6961bc12d03862497a Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Wed, 13 Mar 2013 13:51:20 -0500 Subject: haswell: use dynamic cbmem Convert the existing haswell code to support reloctable ramstage to use dynamic cbmem. This patch always selects DYNAMIC_CBMEM as this option is a hard requirement for relocatable ramstage. Aside from converting a few new API calls, a cbmem_top() implementation is added which is defined to be at the begining of the TSEG region. Also, use the dynamic cbmem library for allocating a stack in ram for romstage after CAR is torn down. Utilizing dynamic cbmem does mean that the cmem field in the gnvs chromeos acpi table is now 0. Also, the memconsole driver in the kernel won't be able to find the memconsole because the cbmem structure changed.
