sparc: Kill SBUS DVMA layer.

2008-08-29T09:13:10+00:00

This thing was completely pointless.

Just find the OF device in the parent of drivers that want to program
this device, and map the DMA regs inside such drivers too.

This also moves the dummy claim_dma_lock() and release_dma_lock()
implementation to floppy_32.h, which makes it handle this issue
just like floppy_64.h does.

[SCSI] m68k: new mac_esp scsi driver

2008-04-27T17:19:57+00:00

Replace the mac_esp driver with a new one based on the esp_scsi core.

For esp_scsi: add support for sync transfers for the PIO mode, add a new
esp_driver_ops method to get the maximum dma transfer size (like the old
NCR53C9x driver), and some cleanups.

[SCSI] esp_scsi: Make cur_residue and tot_residue signed.

2008-04-27T15:03:16+00:00

Many of the overflow checks test whether the value has
gone negative, and we want to retain such checks.

[SCSI] ESP: Revert ESP_BUS_TIMEOUT back down to 250

2007-07-31T15:51:25+00:00

This reverts d73f5222a618a91452d41c29f5996ce3d9c63673

The bug that made us increase ESP_BUS_TIMEOUT to 275 turned out to be
a memset bug on 32-bit sparc.

It is better to put this back at the correct timeout value than to
leave it increased when there is no reason for doing so.

[SCSI] ESP: Increase ESP_BUS_TIMEOUT to 275.

2007-07-21T00:35:38+00:00

This matches the original driver's value and seems to be
necessary for some disks on sun4c systems.

[SCSI] SUNESP: Complete driver rewrite to version 2.0

2007-04-27T07:26:46+00:00

Major features:

1) Tagged queuing support.
2) Will properly negotiate for synchronous transfers even on
   devices that reject the wide negotiation message, such as
   CDROMs
3) Significantly lower kernel stack usage in interrupt
   handler path by elimination of function vector arrays,
   replaced by a top-level switch statement state machine.
4) Uses generic scsi infrastructure as much as possible to
   avoid code duplication.
5) Automatic request of sense data in response to CHECK_CONDITION
6) Portable to other platforms using ESP such as DEC and Sun3
   systems.
