The position of jump_tags was shifted every time a new field was added to struct jump_data. This broke the sysjump hook badly. To make this more scalable, add a header_size field in struct jump_data. Then the new code can always prepend (or reduce if jump_data becomes smaller) some spaces between jump_data and jump_tags. BUG=chrome-os-partner:9447 TEST=EC upgrade from EC 517 (2231) to this version, and keyboard keeps working. Note that EC 526 (2235) to this version is not working because we have no way to identify that header version change. Change-Id: If1b506c6f7d22e5affaaf8ada15990f60d2f957a
- EC Lib
This wraps Blizzard driverlib and implements the EC chip interface defined
by Google. See below diagram for architecture.
