commit 763d04eda4c518e8181460c86f3907e49a8d4659 Author: Vadim Bendebury vbendeb@chromium.org Date: Thu Aug 6 14:11:40 2015 -0700
Clean up coreboot and libpayload tag definitions
The coreboot table tags used to differentiate between different optional components of the coreboot table are defined all over the place in the include file. This makes it difficult to avoid accidental duplication.
Defining them in one place will make code maintenance much easier. There were a few conflicts in the table which have now been resolved. This change will require simultaneous rebuild of coreboot and libpayload.
No actual testing has been done with this patch.
