Subject: libqos/ahci: Add ide cmd properties
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=716b64079ceaa6fede724f8a24a24b0209fa5173;p=qemu.git

libqos/ahci: Add ide cmd properties

Add a structure that defines some properties of various IDE commands.
These will be used to simplify the interface to the libqos AHCI calls,
lessening the redundancy of specifying and respecifying properties of
commands to various helper functions.
