part: extract MBR signature from partitions

2017-09-20T08:20:19+00:00

EFI client programs need the signature information from the partition
table to determine the disk a partition is on, so we need to fill that
in here.

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.

blk: Use macros for block device vendor/product/rev string size

So far these are using magic numbers. Replace them with macros.

dm: blk: Add a generic function for block device commands

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

Most block devices provide a command (e.g. 'sata', 'scsi', 'ide') and
these commands generally do the same thing. This makes it harder to
maintain this code and keep it consistent.

We now have a block device interface which is either implemented by driver
model (when CONFIG_BLK is enabled) or with a legacy interface. Therefore
it is possible to handle most of what these commands do with generic code.

Add a new generic function to process block-device commands using the
interface type and the current device number for that type.

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.

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: blk: Fix warning on !CONFIG_BLK

2017-06-10T14:01:05+00:00

When we don't have CONFIG_BLK defined we don't have a forward
declaration of struct udevice, and thus get a warning about it on
blk_get_from_parent(), which we only have when CONFIG_BLK is set.  Move
the declaration of blk_get_from_parent() to be with the other CONFIG_BLK
parts.

Many devices support a child block device (e.g. MMC, USB). Add a

dm: blk: Allow finding block devices without probing

Sometimes it is useful to be able to find a block device without also
probing it. Add a function for this as well as the associated test.
