sata_fsl: Split hard and soft reset

2009-11-19T23:18:17+00:00

Split sata_fsl_softreset() into hard and soft resets to make
error-handling more efficient & device and PMP detection more
reliable.

Also includes fix for PMP support, driver tested with Sil3726,
Sil4726 & Exar PMP controllers.

[AV: Also fixes resuming from deep sleep on MPC8315 CPUs]

sata_fsl: Fix the command description of FSL SATA controller

2009-05-15T18:14:08+00:00

The bit 11 of command description is reserved bit in Freescale
SATA controller and needs to be set to '1'.  This is needed to
make sure the last write from the controller to the buffer
descriptor is seen before an interrupt is raised.

sata_fsl: Fix compile warnings

2009-05-15T18:14:01+00:00

We we build with dma_addr_t as a 64-bit quantity we get:

drivers/ata/sata_fsl.c: In function 'sata_fsl_fill_sg':
drivers/ata/sata_fsl.c:340: warning: format '%x' expects type 'unsigned int', but argument 4 has type 'dma_addr_t'

sata_fsl: Return non-zero on error in probe()

2009-01-16T15:23:58+00:00

while I was looking over kernel sources I've found this small bug.

Formerly, zero was returned even if an error happened.

libata: make SCR access ops per-link

2008-09-29T04:22:28+00:00

Logically, SCR access ops should take @link; however, there was no
compelling reason to convert all SCR access ops when adding @link
abstraction as there's one-to-one mapping between a port and a non-PMP
link.  However, that assumption won't hold anymore with the scheduled
addition of slave link.

Make SCR access ops per-link.

[libata] sata_fsl: Fix broken driver, add port multiplier (PMP) support

2008-05-30T16:39:44+00:00

The following commit (4c9bf4e799ce06a7378f1196587084802a414c03):
libata: replace tf_read with qc_fill_rtf for non-SFF drivers

Broke the sata_fsl.c driver in 2.6.26-rc.  I know the following patch fixes
the issue, it clearly also adds port multipler support.  The current
2.6.26-rc driver is broken.

On boot with debug enabled we get something like (w/o this patch):

spurious interrupt!!, CC = 0x1
interrupt status 0x1
xx_scr_read, reg_in = 1
spurious interrupt!!, CC = 0x1
interrupt status 0x1
xx_scr_read, reg_in = 1
spurious interrupt!!, CC = 0x1
interrupt status 0x1
xx_scr_read, reg_in = 1

.. continues for ever.

This change fixes this as a side effect of adding port multiplier support.
