dm: blk: Use uclass_find_first/next_device() in blk_first/next_device()

2017-12-13T02:53:45+00:00

This patch changes the calls to uclass_first/next_device() in blk_first/
next_device() to use uclass_find_first/next_device() instead. These functions
don't prepare the devices, which is correct in this case.

With this patch applied, the "usb storage" command now works again as
expected:

=> usb storage
  Device 0: Vendor: SanDisk Rev: 1.00 Prod: Ultra
  Type: Removable Hard Disk
  Capacity: 58656.0 MB = 57.2 GB (120127488 x 512)

Without this patch, it used to generate this buggy output:

=> usb storage
Card did not respond to voltage select!
mmc_init: -95, time 26
No storage devices, perhaps not 'usb start'ed..?

blk: Remove various places that do flush cache after read

2017-09-15T12:05:10+00:00

All these places seem to inherit the codes from the MMC driver where
a FIXME was put in the comment. However the correct operation after
read should be cache invalidate, not flush.

The underlying drivers should be responsible for the cache operation.
Remove these codes completely.

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.

block: ide: Don't bother to create BLK device if no CDROM inserted

2017-09-10T16:27:40+00:00

When there is no CDROM inserted, the block size is zero hence there
is no need to create a BLK device for it.

This converts the IDE driver to driver model so that block read and
write are fully functional.

dm: blk: Update return value in blk_create_devicef()

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

This returns 'ret' but the value is always zero. Update it to simply
return 0, for clarity.

dm: blk: Add a function to find an interface-type name

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

Add a function to find the name of an interface type (e.g. "sata", "scsi")
from the interface type enum.

This is useful for generic code (not specific to SATA or SCSI, for
example) that wants to display the type of interface it is dealing with.
