From: Sam Eiderman shmuel.eiderman@oracle.com
Add logical geometry variables to BlockConf.
A user can now supply "lcyls", "lheads" & "lsecs" for any HD device that supports CHS ("cyls", "heads", "secs").
These devices include: * ide-hd * scsi-hd * virtio-blk-pci
In future commits we will use the provided LCHS and pass it to the BIOS through fw_cfg to be supplied using INT13 routines.
