From 0dc7354760e889074472ef17652c7f270f3aa529 Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Thu, 16 Jul 2015 16:07:02 -0500 Subject: amd: raminit sysinfo offset fix The sysinfo object within the k8 ram init is used to communicate progess/status from all the nodes in the system. However, the code was assuming where the sysinfo object lived in cache-as-ram. The layout of cache-as-ram is dynamic so one needs to do the lookup of the correct address at runtime. The way the amd code is compiled by #include'ing .c files makes the solution a little more complex in that some cache-as-ram support code needed to be refactored.
