Move most CONFIG_HAVE_BLOCK_DEVICE to Kconfig

2018-02-09T00:09:03+00:00

config_fallbacks.h has some logic that sets HAVE_BLOCK_DEVICE
based on a list of enabled options.  Moving HAVE_BLOCK_DEVICE to
Kconfig allows us to drastically shrink the logic in
config_fallbacks.h

blk: dm: make blk_create_device() take a number of block instead of a size

2017-09-12T03:43:58+00:00

There is an overflow problem when taking the size instead of the number
of blocks in blk_create_device(). This results in a wrong device size: the
device apparent size is its real size  modulo 4GB.
Using the number of blocks instead of the device size fixes the problem and
is more coherent with the internals of the block layer.

env: Rename common functions related to setenv()

2017-08-16T12:23:32+00:00

We are now using an env_ prefix for environment functions. Rename these
commonly used functions, for consistency. Also add function comments in
common.h.

dm: mmc: Allow disabling driver model in SPL

2017-08-01T02:58:00+00:00

At present if U-Boot proper uses driver model for MMC, then SPL has to
also. While this is desirable, it places a significant barrier to moving
to driver model in some cases. For example, with a space-constrained SPL
it may be necessary to enable CONFIG_SPL_OF_PLATDATA which involves
adjusting some drivers.

Add new SPL versions of the options for DM_MMC, DM_MMC_OPS and BLK. By
default these follow their non-SPL versions, but this can be changed by
boards which need it.

dm: scsi: Drop scsi_init() when driver model is used

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

This function should not be used with driver model. Update the code to
reflect this.

dm: scsi: Split out the bus scanning code

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

Split out the code that scans a single SCSI bus into a separate function.
This will allow it to be used from driver model.

dm: scsi: Adjust return value of scsi_exec()

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

Change this function to return an error number instead of true/false.
This allows us to return a proper error number.

dm: scsi: Add operations for SCSI devices

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

The SCSI uclass currently has no operations. It just uses the global SCSI
functions. Fix this by adding operations to the only two drivers that use
the uclass, and replacing the global functions with those defined locally
in the SCSI code.

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.
