In moving from v0.8 to v0.9 the Firmware Handoff specification made some changes, including:
- Use a packed format for headers to reduce space - Add an explicit alignment field in the header - Renumber all the tags and reduce their size to 24 bits - Drop use of the blob header to specify alignment, in favour of a 'void' blob type
This series attempts to align to that specification, including updating the API and tests. It is likely that refinements will be made as other projects implement the spec too.
As before the code is dual-licensed, to permit use in projects with a permissive license.
