[Qemu-devel] [PATCH v3] Issue a deprecation warning if the user specifies the "-hdachs" option.

[Qemu-devel] [PATCH v3] Issue a deprecation warning if the user specifies the "-hdachs" option.

[Thomas Huth]

If the user needs to specify the disk geometry, the corresponding
parameters of the "-device ide-hd" option should be used instead.
"-hdachs" is considered as deprecated and might be removed soon.

 v3:
 - Recommend to use the parameters of -device ide-hd instead
 - Also add the deprecation warning to the documentation
