[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. Signed-off-by: Ashish Kalra <ashish.kalra@freescale.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
