Thanks Geert. You do make it look easy to avoid regressions!
sun3x_esp and mac_esp are platform devices so I guess I should convert
sun3_scsi and mac_scsi to platform devices also. I'm not sure about
atari_scsi, perhaps there's a different bus that can probe it. Michael?
I see that the PCI driver (dmx3191d) and the ARM drivers (oak and
cumana_1) have already been converted. So the remaining NCR5380 drivers
that still use scsi_register() are the ISA cards: g_NCR5380, dtc,
pas16 and t128.
I don't have any ISA hardware. I certainly don't mind if those drivers
ultimately get removed along with scsi_register() itself.
Those ISA drivers depend on functionality in the NCR5380.c core driver
that was discarded by the other two core driver variants (atari_NCR5380.c
and sun3_NCR5380.c) such as DONT_USE_INTR, UNSAFE, DMA_WORKS_RIGHT,
AUTOPROBE_IRQ, USLEEP_POLL, NCR53C400.
If it were not for the ISA cards, we may not need three variations on the
core driver.
