Hmm, why this name? Doesn't look intuitive to me.

I'd name that
For CSM, the highest priority is zero. In SeaBIOS that means "don't", and
the highest priority is 1.
So we end up with the fun outcome that booting from NVMe worked only
when it *wasn't* selected as the primary boot target, because we don't
actually run the nvme_controller_setup() thread for an

v1:
Non-standard logical geometries break under QEMU.
A virtual disk which contains an operating system which depends on
logical geometries (consistent values being reported from BIOS INT13
AH=08) will most likely break under QEMU/SeaBIOS if it has non-standard
logical geometries - for example
Move device name construction to a separate function.
We will reuse this function in the following commit to pass logical CHS
parameters through fw_cfg much like we currently pass bootindex.

Add QTest tests to check the logical geometry override option.
The tests in hd-geo-test are out of date - they only test IDE and do not
test interesting MBRs.
I added a few helper functions which will make adding more tests easier.
QTest's fw_cfg helper functions support only legacy fw_cfg, so
Relevant devices are:
* ide-hd (and ide-cd, ide-drive)
* scsi-hd (and scsi-cd, scsi-disk, scsi-block)
* virtio-blk-pci
We do not call del_boot_device_lchs() for ide-* since we don't need to -
IDE block devices do not support unplugging.

We will need to add LCHS removal logic to scsi-hd's unrealize() in the

Read bios geometry for boot devices from fw_cfg.
By receiving LCHS values directly from QEMU through fw_cfg we will be
