The current GPL only licensing on the device trees makes it very
impractical for other software components licensed under another
license.
To make it easier to reuse them, the device trees for UniPhier
SoCs and boards have already been dual-licensed in Linux.
Follow this trend in U-boot too.

Some archs/boards specify their own default by pre-defining the config
which causes the Kconfig system to mix up the order of the configs in
the defconfigs... This will cause merge pain if allowed to proliferate.
Remove the configs that behave this way from the archs.
A few configs still remain, but that is because they only exist as
defaults and do not have a proper Kconfig entry. Those appear to be:

DRA7/AM57xx devices can be operated in many different configurations.
When the SoC is supposed to support a configuration where low power mode
state may involve the SoC completely powered off and DDR is in self
refresh, SoC EMIF controller should not be the master of the reset
signal and an external entity might be in control of things.
The default configuration of Linux on TI evms involve not powering off
the voltage rails (due to various reasons including reliability concerns)
and must not allow DDR reset to be controlled by EMIF. On platforms
where external entity might control the reset signal, this configuration
will be a "dont care".

Currently on sun6i after a "reset" the prompt returns and the user can
even type stuff until the watchdog triggers and does the actual reset.
This is somewhat unexpected behavior for the "reset" command, this
commit adds an endless loop to wait for the watchdog to trigger so that
we do not return to the prompt.

The recent changes for hw leveling on am33xx were not intended for
DDR2 boards, only DDR3. Update emif_sdram_type to take a sdram_config
value to check against. This lets us pass in the value we would use to
configure, when we have not yet configured the board yet. In other cases
update the call to be as functional as before and check an already
programmed value in.

In addition to the regular mux configuration, certain pins of DRA7
require to have "manual mode" also programmed, when predefined
delay characteristics cannot be used for the interface.
struct iodelay_cfg_entry is introduced for populating
manual mode IO timings.
For configuring manual mode, along with the normal pad
configuration do the following steps:
- Select MODESELECT field of each assocaited PAD.
CTRL_CORE_PAD_XXX[8]:MODESELECT = 1(Enable MANUAL_MODE macro along with mux)
- Populate A_DELAY, G_DELAY values that are specified in DATA MANUAL.
And pass the offset of the CFG_XXX register in iodelay_cfg_entry.

On DRA7, in addition to the regular muxing of pins, an additional
hardware module called IODelay which is also expected to be
configured. This "IODelay" module has it's own register space that is
independent of the control module.
It is advocated strongly in TI's official documentation considering
the existing design of the DRA7 family of processors during mux or
IODelay recalibration, there is a potential for a significant glitch
which may cause functional impairment to certain hardware. It is
hence recommended to do muxing as part of IOdelay recalibration.
IODELAY recalibration sequence:
- Complete AVS voltage change on VDD_CORE_L
- Unlock IODLAY config registers.
- Perform IO delay calibration with predefined values.
- Isolate all the IOs
- Update the delay mechanism for each IO with new calibrated values.
- Configure PAD configuration registers
- De-isolate all the IOs.
- Relock IODELAY config registers.

In addition to the regular mux configuration, certain pins of DRA7
require to have "virtual mode" also programmed.
This allows for predefined delay characteristics to be used by the SoC
to meet timing characterstics needed for the interface.
Provide easy to use macro to do the same.
For configuring virtual mode, along with normal pad configuration add
the following two steps:
- Select MODESELECT field of each assocaited PAD.
CTRL_CORE_PAD_XXX[8]:MODESELECT = 1
- DELAYMODE filed should be configured with value given in DATA Manual.
CTRL_CORE_PAD_XXX[7:4]:DELAYMODE =[0-15] (as given in DATA manual).
