[libata] pata_bf54x: Support sg list in bmdma transfer.

2012-01-18T01:49:28+00:00

BF54x on-chip ATAPI controller allows maximum 0x1fffe bytes to be transfered
in one ATAPI transfer. So, set the max sg_tablesize to 4.

[libata] enable ata port async suspend

2012-01-18T01:48:06+00:00

This saves devices suspend/resume time.

Tested system suspend/resume with SATA IDE/AHCI mode 3 times.
Below is the time took for devices suspend/resume.

module_param: make bool parameters really bool (drivers & misc)

2012-01-12T23:02:20+00:00

module_param(bool) used to counter-intuitively take an int.  In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.

It's time to remove the int/unsigned int option.  For this version
it'll simply give a warning, but it'll break next kernel version.

New feature development

This adds support for new features, and contains stuff from most
platforms. A number of these patches could have fit into other
branches, too, but were small enough not to cause too much
confusion here.

ahci: support the STA2X11 I/O Hub

2012-01-09T00:24:06+00:00

The AHCI controller found in the STA2X11 chip uses BAR number 0
instead of 5. Also, the chip's fixup code sets a special DMA mask
for all of its PCI functions, and the mask must be preserved here.

pata_bf54x: fix BMIDE status register emulation

2012-01-09T00:24:02+00:00

The author of this driver clearly wasn't familiar with the BMIDE specification
(also known as SFF-8038i) when he implemented the bmdma_status() method: first,
the interrupt bit of the BMIDE status register corresponds to nothing else but
INTRQ signal (ATAPI_DEV_INT here); second, the error bit is only set if the
controller encounters issue doing the bus master transfers, not on the IDE DMA
burst termination interrupts like here (moreover, setting the error bit doesn't
cause an interrupt).  We now need to disable all those unused interrupts...

(The only thing I couldn't figure out is how to flush the FIFO to memory once
the interrupt happens as required by the mentioned spec.)
