Igor Pylypiv 5454329595 scsi: pm80xx: Set RETFIS when requested by libsas
By default PM80xx HBAs return FIS only when a drive reports an error.
The RETFIS bit forces the controller to populate FIS even when a drive
reports no error.

Ajish Koshy 80cac47b08 scsi: pm80xx: Handle non-fatal errors
Firmware expects host driver to clear scratchpad rsvd 0 register after
non-fatal error is found.

This is done when firmware raises fatal error interrupt and indicates
non-fatal error. At this point firmware updates scratchpad rsvd 0 register
with non-fatal error value. Here host has to clear the register after
reading it during non-fatal errors.

Rename:

 - MSGU_HOST_SCRATCH_PAD_6 to MSGU_SCRATCH_PAD_RSVD_0

 - MSGU_HOST_SCRATCH_PAD_7 to MSGU_SCRATCH_PAD_RSVD_1

Damien Le Moal e5039a92f1 scsi: pm8001: Fix use of struct set_phy_profile_req fields
In mpi_set_phy_profile_req() and pm8001_set_phy_profile_single(), use
cpu_to_le32() to initialize the ppc_phyid field of struct
set_phy_profile_req. Furthermore, fix the definition of the reserved field
of this structure to be an array of __le32, to match the use of
cpu_to_le32() when assigning values. These changes remove several sparse
type warnings.

John Garry 62afb379a0 scsi: pm8001: Fix bogus FW crash for maxcpus=1
According to the comment in check_fw_ready() we should not check the
IOP1_READY field in register SCRATCH_PAD_1 for 8008 or 8009 controllers.

However we check this very field in process_oq() for processing the highest
index interrupt vector. The highest interrupt vector is checked as the FW
is programmed to signal fatal errors through this irq.

Change that function to not check IOP1_READY for those mentioned
controllers, but do check ILA_READY in both cases.

The reason I assume that this was not hit earlier was because we always
allocated 64 MSI(X), and just did not pass the vector index check in
process_oq(), i.e.  the handler never ran for vector index 63.

akshatzen d71023af4b scsi: pm80xx: Do not busy wait in MPI init check
We do not need to busy wait during mpi_init_check() since it is not being
invoked in atomic context. mpi_init_check() is being called from
pm8001_pci_resume(), pm8001_pci_probe(). Hence we are replacing udelay with
msleep.

akshatzen 48cd6b38eb scsi: pm80xx: Avoid busywait in FW ready check
In function check_fw_ready() we busy wait using udelay. The CPU is not
released and we see need_resched failures.

Busy waiting is not necessary since we are in process context and we can
sleep instead. Replace udelay with msleep of 20 ms intervals while waiting
for firmware to become ready.

It has been verified that check_fw_ready is not being used in interrupt
context anywhere, hence it is safe to make this change.
