* cleanup: Remove checkpatch warningsRandall Spangler2013-12-191-1/+1
| | | | | | | | | | | | | | | | This make minor syntactic changes and renames some camel-cased symbols to keep checkpatch from complaining. The goal is to reduce the temptation to use 'repo upload --no-verify'. This is a big furball of find/replace, but no functional changes.

* Clean up vboot hash supportRandall Spangler2012-10-251-0/+222
This copies the parts of sha256.c that we need from vboot_reference, and removes the explicit dependency on vboot_reference. That dependency was a good idea when we were doing full verified boot in the EC, but is now overkill and makes it harder for others to reuse the EC code. This also lets us call EC functions directly instead of needing vboot_stub.cc; that reduces code size by ~100 bytes.
