[PATCH v7 0/5] fw_cfg: Add FW_CFG_DATA_GENERATOR; crypto: Add tls-cipher-suites

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

Hi,

This series has two parts:

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

- Then we add the tls-cipher-suites object, and let it
  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.

[*]: https://github.com/tianocore/edk2/blob/master/OvmfPkg/README
