libata-sff: remove dead code

2014-05-04T19:01:42+00:00

Ever since v2.6.19 the code contains a check for CONFIG_NO_ATA_LEGACY.
But that macro has never been defined. Apparently no one ran into
problems on platforms that do not support compatibility mode. So remove
this code that has been dead for over seven years.

ide/ata: Add module.h to the implicit modular users

2011-10-31T23:31:37+00:00

A pending cleanup will mean that module.h won't be implicitly
everywhere anymore.  Make sure the modular drivers in the ide dir
are actually calling out for  explicitly in advance.

libata: make ata_sff_data_xfer_noirq() work with 32-bit PIO

2011-10-14T17:37:31+00:00

Always use ata_sff_data_xfer32() in ata_sff_data_xfer_noirq()
so the latter can be also used for host controllers supporting
32-bit PIO operations.

It is a completely safe thing to do because if 32-bit PIO is
not supported or enabled ata_sff_data_xfer32() will fallback
to a standard method.

libata: reduce ata_pci_[sff,bmdma]_init_one() size

2011-10-14T17:01:17+00:00

Turn both helpers (which are used only during LLDs initialization
time and thus are not performance sensitive) into wrappers around
the new ata_pci_init_one() function, this cuts 20 LOC and saves
~1.1k of the output code size (x86-64):

libata: clear PIO pad area

2011-10-08T03:46:25+00:00

ata_sff_data_xfer[32]() use pad area if the transfer size isn't
multiple of transfer size; however, this area wasn't cleared and
garbage data in pad area could be transferred to the device.  Make
sure the pad area is cleared.
