libata: skip old error history when counting probe trials

2012-05-07T15:53:36+00:00

commit 6868225e3e92399068be9a5f1635752d91012ad5 upstream.

Commit d902747("[libata] Add ATA transport class") introduced
ATA_EFLAG_OLD_ER to mark entries in the error ring as cleared.

But ata_count_probe_trials_cb() didn't check this flag and it still
counts the old error history. So wrong probe trials count is returned
and it causes problem, for example, SATA link speed is slowed down from
3.0Gbps to 1.5Gbps.

Fix it by checking ATA_EFLAG_OLD_ER in ata_count_probe_trials_cb().

pata_legacy: correctly mask recovery field for HT6560B

2012-04-02T17:32:06+00:00

commit 9716387311c790de381214c03e7f1b72b91a8189 upstream.

According to the HT6560H datasheet, the recovery timing field is 4-bit wide,
with a value of 0 meaning 16 cycles. Correct obvious thinko in the recovery
field mask.

ahci: move AHCI_HFLAGS() macro to ahci.h

2012-04-02T17:32:06+00:00

commit 55d5ec316627b64c3764e4c1b4b8e1988e272c1f upstream.

We will need this macro in both ahci.c and ahci_platform.c, so just move it
to the header.

ahci: add AHCI_HFLAG_DELAY_ENGINE host flag

2012-04-02T17:32:06+00:00

commit 66583c9fa63d05d5580e409f9a58d3cad6d76d17 upstream.

The following commit was intended to fix problems with specific AHCI
controller(s) that would become bricks if the AHCI specification was not
followed strictly (that is, if ahci_start_engine() was called while the
controller was in the wrong state):

    commit 7faa33da9b7add01db9f1ad92c6a5d9145e940a7
    ahci: start engine only during soft/hard resets

However, some devices currently have issues with that fix, so we must
implement a flag that delays the ahci_start_engine() call only for specific
controllers.

This commit simply introduces the flag, without enabling it in any driver.

Note that even when AHCI_HFLAG_DELAY_ENGINE is not enabled, this patch does
not constitue a full revert to commit 7faa33da; there is still a change in
behavior to the ahci_port_suspend() failure path.

pata/at91: use newly introduced SMC accessors

2012-02-13T17:31:37+00:00

pata_at91 driver is broken since faee0cc:
"make smc register base soc independent"
Fix it with newly introduced SMC accessors.

The overall action of removal of at91_sys_read/write will allow
to use the pata_at91 on a single zImage kernel.
