kconfig: remove unneeded dependency on !SPL_BUILD

2015-02-24T22:06:27+00:00

Now CONFIG_SPL_BUILD is not defined in Kconfig, so
"!depends on SPL_BUILD" and "if !SPL_BUILD" are redundant.

dm: Add support for all targets which requires MANUAL_RELOC

2015-02-12T22:17:29+00:00

Targets with CONFIG_NEEDS_MANUAL_RELOC do not use REL/RELA
relocation (mostly only GOT) where functions aray are not
updated. This patch is fixing function pointers for DM core
and serial-uclass to ensure that relocated functions are called.

dm: introduce dev_get_addr interface

2015-02-12T22:17:29+00:00

Abstracting dev_get_addr can improve drivers that want to
get device's address.

dm: Add Kconfig options for driver model SPL support

2015-02-12T17:35:33+00:00

The SPL support cannot be enabled yet, but we can add the Kconfig
options in preparation for this.

dm: Expand and complete Kconfig in drivers/

2015-02-12T17:35:33+00:00

Expand the help messages for each driver. Add missing Kconfig for I2C,
SPI flash and thermal.

We don't want to bind devices which should never be used.

dm: core: Allow uclass to set up a device's child before it is probed

2015-01-30T00:09:56+00:00

Some buses need to set up their devices before they can be used. This setup
may well be common to all buses in a particular uclass. Support a common
pre-probe method for the uclass, called before any bus devices are probed.

dm: core: Allow the uclass to set up a device's child after binding

2015-01-30T00:09:56+00:00

For buses, after a child is bound, allow the uclass to perform some
processing. This can be used to figure out the address of the child (e.g.
the chip select for SPI slaves) so that it is ready to be probed.

This avoids bus drivers having to repeat the same process, which really
should be done by the uclass, since it is common.

dm: core: Allow uclasses to specify private data for a device's children

2015-01-30T00:09:55+00:00

In many cases the per-child private data for a device's children is defined
by the uclass rather than the individual driver. For example, a SPI bus
needs to store information about each of its children, but all SPI drivers
store the same information. It makes sense to allow the uclass to define
this data.

If the driver provides a size value for its per-child private data, then use
it. Failng that, fall back to that provided by the uclass.

dm: core: Add a flag to control sequence numbering

2015-01-30T00:09:55+00:00

At present we try to use the 'reg' property and device tree aliases to give
devices a sequence number. The 'reg' property is often actually a memory
address, so the sequence numbers thus-obtained are not useful. It would be
better if the devices were just sequentially numbered in that case. In fact
neither I2C nor SPI use this feature, so drop it.

Some devices need us to look up an alias to number them within the uclass.
Add a flag to control this, so it is not done unless it is needed.

Adjust the tests to test this new behaviour.
