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