block: sata: ceva: drop extraneous netdev.h include

2017-06-20T14:40:58+00:00

Drop include of netdev.h as it's a SATA driver not a network driver.

powerpc, 8xx: remove support for 8xx

2017-06-12T12:37:55+00:00

There was for long time no activity in the 8xx area.
We need to go further and convert to Kconfig, but it
turned out, nobody is interested anymore in 8xx,
so remove it (with a heavy heart, knowing that I remove
here the root of U-Boot).

dm: blk: Add a way to obtain a block device from its parent

2017-06-09T11:25:16+00:00

Many devices support a child block device (e.g. MMC, USB). Add a
convenient way to get this device given the parent device.

dm: blk: Improve block device claiming

2017-06-01T13:03:05+00:00

The intention with block devices is that the device number (devnum field
in its descriptor) matches the alias of its parent device. For example,
with:

	aliases {
		mmc0 = "/sdhci@700b0600";
		mmc1 = "/sdhci@700b0400";
	}

we expect that the block devices for mmc0 and mmc1 would have device
numbers of 0 and 1 respectively.

Unfortunately this does not currently always happen. If there is another
MMC device earlier in the driver model data structures its block device
will be created first. It will therefore get device number 0 and mmc0
will therefore miss out. In this case the MMC device will have sequence
number 0 but its block device will not.

To avoid this, allow a device to request a device number and bump any
existing device number that is using it. This all happens during the
binding phase so it is safe to change these numbers around. This allows
device numbers to match the aliases in all circumstances.

Add a test to verify the behaviour.

dm: blk: Add a function to find the next block device number

2017-06-01T13:03:05+00:00

At present this code is inline. Move it into a function to allow it to
be used elsewhere.

dm: blk: Allow finding block devices without probing

2017-06-01T13:03:04+00:00

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.

dm: core: Replace of_offset with accessor (part 2)

2017-06-01T13:03:04+00:00

At present devices use a simple integer offset to record the device tree
node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to
access this field through an inline function.

dm: Rename dev_addr..() functions

2017-06-01T13:03:01+00:00

These support the flat device tree. We want to use the dev_read_..()
prefix for functions that support both flat tree and live tree. So rename
the existing functions to avoid confusion.

In the end we will have:

   1. dev_read_addr...()    - works on devices, supports flat/live tree
   2. devfdt_get_addr...()  - current functions, flat tree only
   3. of_get_address() etc. - new functions, live tree only

All drivers will be written to use 1. That function will in turn call
either 2 or 3 depending on whether the flat or live tree is in use.

Note this involves changing some dead code - the imx_lpi2c.c file.

Kconfig: Add a CONFIG_IDE option

2017-05-22T16:45:27+00:00

At present IDE support is controlled by CONFIG_CMD_IDE. Add a separate
CONFIG_IDE option so that IDE support can be enabled without requiring
the 'ide' command.

Update existing users and move the ide driver into drivers/block since
it should not be in common/.
