Convert mac_scsi to platform device and eliminate scsi_register().
Platform resources for chip registers now follow the documentation. This
should fix issues with the Mac IIci (and possibly other models too).
Signed-off-by: Finn Thain <fthain@xxxxxxxxxxxxxxxxxxx>
---
The new hwreg_present() call site is not protected by local_irq_save/restore.
This assumes Geert's patch, "Disable/restore interrupts in
hwreg_present()/hwreg_write()", which is commit e4dc601bf99ccd1c in 3.18-rc1.
Changes since v1:
- Use NO_IRQ instead of IRQ_NONE.
- Drop unnecessary MACH_IS_MAC() test.
- Remove static platform_device structs and call
platform_device_register_simple() instead of platform_device_register().
- Platform resources now const and __initconst.
- Add MAC_SCSI_LATE platform resources to avoid PDMA on certain models.
