| * sata: ahci-da850: add a workaround for controller instabilityBartosz Golaszewski2017-01-311-1/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have a use case with the da850 SATA controller where at PLL0 frequency of 456MHz (needed to properly service the LCD controller) the chip becomes unstable and the hardreset operation is ignored the first time 50% of times. The sata core driver already retries to resume the link because some controllers ignore writes to the SControl register, but just retrying the resume operation doesn't work - we need to issue he phy/wake reset again to make it work. Reimplement ahci_hardreset() in the driver and poke the controller a couple times before really giving up.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need a way to retrieve the information about the online state of the link in the ahci-da850 driver. Create a new function: ahci_do_hardreset() which is called from ahci_hardreset() for backwards compatibility, but has an additional argument: 'online' - which can be used to check if the link is online after this function returns. The new routine will be used in the ahci-da850 driver to avoid code duplication when implementing a workaround for tha da850 SATA controller quirk/instability.

| | | | | | | | | | | | | | | | | | | | | | | | | | There's an issue with the da850 SATA controller: if port multiplier support is compiled in, but we're connecting the drive directly to the SATA port on the board, the drive can't be detected. To make SATA work on the da850-lcdk board: first try to softreset with pmp - if the operation fails with -EBUSY, retry without pmp.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | libata-sff.c checks for legacy mode by testing if both primary and secondary ports on a controller are in legacy mode and selects legacy if either one is. However on some south bridge chips (e.g AMD SB600/SB700) the secondary port is not wired, and when it is disabled by setting the disable bit in the PCI header it appears as a fixed legacy port.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For ls1021a, and armv8 chasis 2 socs, sata ecc must be disabled. If ecc register is not found in sata node in dts, report error. This is a chip erratum described as bellow: The Read DMA operations get early termination indication from the controller. This issue is observed as CRC error in the status registers. The issue is due to address collision at address 0 in the dual port memory. The read is a dummy read to flush out the header, but due to collision the controller logs the mbit error reported by the ECC check logic. This results in the early termination of the Read DMA operation by the controller. The issue happens to all the interface speeds(GEN1/2/3) for all the products.

The thermal subsystem already has a check in its header, but that also doesn't cover the THERMAL=m case, so we need a somewhat complex Kconfig expression to handle all cases.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead define the timeout behavior purely based on the host_template eh_timed_out method and wire up the existing transport implementations in the host templates. This also clears up the confusion that the transport template method overrides the host template one, so some drivers have to re-override the transport template one.

* | libata: Fix ATA request senseDamien Le Moal2017-01-061-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For an ATA device supporting the sense data reporting feature set, a failed command will trigger the execution of ata_eh_request_sense if the result task file of the failed command has the ATA_SENSE bit set (sense data available bit). ata_eh_request_sense executes the REQUEST SENSE DATA EXT command to retrieve the sense data of the failed command. On success of REQUEST SENSE DATA EXT, the ATA_SENSE bit will NOT be set (the command succeeded) but ata_eh_request_sense nevertheless tests the availability of sense data by testing that bit presence in the result tf of the REQUEST SENSE DATA EXT command. This leads us to falsely assume that request sense data failed and to the warning message: atax.xx: request sense failed stat 50 emask 0 Upon success of REQUEST SENSE DATA EXT, set the ATA_SENSE bit in the result task file command so that sense data can be returned by ata_eh_request_sense.
