isci: refactor initialization for S3/S4 Based on an original implementation by Ed Nadolski and Artur Wojcik In preparation for S3/S4 support refactor initialization so that driver-load and resume-from-suspend can share the common init path of isci_host_init(). Organize the initialization into objects that are self-contained to the driver (initialized by isci_host_init) versus those that have some upward registration (initialized at allocation time asd_sas_phy, asd_sas_port, dma allocations). The largest change is moving the the validation of the oem and module parameters from isci_host_init() to isci_host_alloc(). The S3/S4 approach being taken is that libsas will be tasked with remembering the state of the domain and the lldd is free to be forgetful. In the case of isci we'll just re-init using a subset of the normal driver load path.

[SCSI] isci: oem parameter format v1.3 (cable select) v1.3 allows the attenuation of the attached cables to be specified to the driver in terms of 'short', 'medium', and 'long' (see probe_roms.h). These settings (per phy) are retrieved from the platform oem-parameters (BIOS rom) or via a module parameter override.

[SCSI] isci: overriding max_concurr_spinup oem parameter by max(oem, user) Fixes bug where max_concurr_spinup oem parameter should be overriden by max_concurr_spinup user parameter. Override should happen only when max_concurr_spinup user parameter is specified in command line (greater than 0). Also this fix shortens variables representing max_conxurr_spinup for oem and user parameters.

isci: retire scic_sds_ and scic_ prefixes The distinction between scic_sds_ scic_ and sci_ are no longer relevant so just unify the prefixes on sci_. The distinction between isci_ and sci_ is historically significant, and useful for comparing the old 'core' to the current Linux driver. 'sci_' represents the former core as well as the routines that are closer to the hardware and protocol than their 'isci_' brethren. sci == sas controller interface. Also unwind the 'sds1' out of the parameter structs. Reported-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Dan Williams <dan.j.williams@intel.com>

isci: fix oem parameter initialization and mode detection 1/ Since commit 858d4aa7 "isci: Move firmware loading to per PCI device" we have been silently falling back to built-in defaults for the parameter settings by skipping the call to scic_oem_parameters_set(). 2/ The afe parameters from the firmware were not being honored 3/ The latest oem parameter definition flips the mode_type values which are now 0: for APC 1: for MPC. For APC we need to make sure all the phys default to the same address otherwise strict_wide_ports will cause duplicate domains. 4/ Fix up the driver announcement to indicate the source of the parameters. 5/ Fix up the sas addresses to be unique per controller (in the fallback case) Signed-off-by: Dave Jiang <dave.jiang@intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
