[PATCH v10 0/5] fw_cfg: Add FW_CFG_DATA_GENERATOR; crypto: Add tls-cipher-suites

[Philippe Mathieu-Daudé]

Hi,

This series has 3 parts:

- First we add the tls-cipher-suites object

- We add the ability to QOM objects to produce data
  consumable by the fw_cfg device,

- Then we let the tls-cipher-suites object implement
  the FW_CFG_DATA_GENERATOR interface.

This is required by EDK2 'HTTPS Boot' feature [*] to tell
the guest which TLS ciphers it can use.

Since v9:
- intent to address Daniel suggestions, rewrite of crypto/* code
Since v8:
- addressed Laszlo review comments (reword/typos)
Since v7:
- addressed Laszlo review comments
Since v6:
- addressed Laszlo & Daniel review comments
Since v5:
- Complete rewrite after chatting with Daniel Berrangé
Since v4:
- Addressed Laszlo comments (see patch#1 description)
Since v3:
- Addressed Markus' comments (do not care about heap)
Since v2:
- Split of
Since v1:
- Addressed Michael and Laszlo comments.

Phil.
