Hi,
This series consists of:
- add fw_cfg_add_file_from_host()
- add edk2_add_host_crypto_policy() and the Edk2Crypto object
The Edk2Crypto object is used to hold configuration values specific
to EDK2.
The edk2_add_host_crypto_policy() function loads crypto policies
from the host, and register them as fw_cfg named file items.
So far only the 'https' policy is supported.
A usercase example is the 'HTTPS Boof' feature of OVMF [*].
Usage example:
$ qemu-system-x86_64 \
--object edk2_crypto,id=https,\
ciphers=/etc/crypto-policies/back-ends/openssl.config,\
cacerts=/etc/pki/ca-trust/extracted/edk2/cacerts.bin
(On Fedora these files are provided by the ca-certificates and
crypto-policies packages).

Since v3:
- Addressed Markus' comments (do not care about heap)
Since v2:
- Split of
Since v1:
- Addressed Michael and Laszlo comments.
Please review,
Phil.
