This patchset enables DMA interface support for writing fw-cfg files in
libqtest. The first patch is just a code refactoring so that fw-cfg
directory parsing can be part of a separate helper function.
The second patch is the actual patch that introduces two new apis for
writing and reading fw-cfg files using DMA interface. The apis are
tested by writing a qtest for vmfwupdate. Please see
tests/qtest/vmfwupdate-test.c changes in
https://gitlab.com/anisinha/qemu/-/commit/4d94a67d1cf29780f136a8bd2c21ff0e57c7b2db
To test the code, you can pull in this branch
https://gitlab.com/anisinha/qemu/-/commits/fuki-hyperface which has
vmfwupdate changes on top of the patches sent in this series.
