This patchset contains more ESP fixes from my attempts to boot MacOS under
the QEMU q800 machine (along with a related NetBSD fix).

With these patches it is possible for the MacOS toolbox ROM and MacOS drivers
to detect and access SCSI drives and CDROMs during the MacOS boot process.

This patchset has been tested on top of the ESP fix series posted yesterday
(see https://lists.gnu.org/archive/html/qemu-devel/2021-05/msg05763.html) with
the extended set of ESP test images without noticing any regressions.

Ping? I'd be particularly interested if anyone could clarify the history around the code removed by patch 4...


ATB,

Mark.
