dm: scsi: Adjust the 'scsi' command to use blk_common_cmd()

2017-08-17T07:44:16+00:00

Instead of having separate code in the 'scsi' command, adjust it to use
the common function.

cmd: scsi: Fix null pointer dereference in 'scsi reset'

2017-07-28T18:02:47+00:00

During 'scsi reset', scsi_bus_reset() is called with udevice pointed
to NULL, which causes exception. As a temporary fix, disable the call
for DM SCSI for now.

dm: scsi: Document and rename the scsi_scan() parameter

2017-07-11T16:08:19+00:00

The 'mode' parameter is actually a flag to determine whether to display
a list of devices found during the scan. Rename it to reflect this, add a
function comment and adjust callers to use a boolean.

dm: scsi: Add a device pointer to scan_exec(), scsi_bus_reset()

2017-07-11T16:08:19+00:00

With driver model these functions need a device pointer. Add one even
when CONFIG_DM_SCSI is not defined. This avoids having ugly conditional
function prototypes, When CONFIG_DM_SCSI is not defined we can just ignore
the pointer.

cmd: scsi: Make private functions static

2016-12-02T13:37:32+00:00

Two functions should be static because they are not exported to any
other file.
Warnings were reported by sparse C=1.

With DM_SCSI this function will return more than one return value to
cover errors.

dm: scsi: Separate the non-command code into its own file

2016-05-17T15:54:43+00:00

At present the SCSI command code includes both the command-processing code
and the core SCSI functions and data structures.

Separate the latter into its own file, adding functions as needed to avoid
the command code accessing data structures directly. This functions use the
new legacy block functions.

With this commit:
- There is no CONFIG option referenced from the command code
- The concept of a 'current SCSI device' is confined to the command code

This will make it easier to convert this code to driver model.

cmd: scsi: Group the command portion together, guard with !CONFIG_SPL_BUILD

2016-03-16T19:03:37+00:00

When we switch to including all linker lists in SPL it is important
to not include commands as that may lead to link errors due to other
things we have already discarded.  In this case, the SCSI code needs a lot
of attention so for now just guard the command portions.
