commit cbedbb4096b76ede506d635864fa35b4d6de0921 Author: Stefan Reinauer reinauer@chromium.org Date: Thu Apr 18 18:01:34 2013 -0700
Eliminate use of pointers in coreboot table
Because pointers can be 32bit or 64bit big, using them in the coreboot table requires the OS and the firmware to operate in the same mode which is not always the case. Hence, use 64bit for all pointers stored in the coreboot table. Guess we'll have to fix this up once we port to the first 128bit machines.
