When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

We have a large number of places where while we historically referenced
gd in the code we no longer do, as well as cases where the code added
that line "just in case" during development and never dropped it.

This converts the following to Kconfig:
CONFIG_CONS_INDEX
We have existing entries for this option in a number of places, with
different guards on them. They're also sometimes used for things not
directly inside of the serial driver. First, introduce a new symbol to
guard the use of CONFIG_CONS_INDEX, so that in the case where we don't
need this for the serial driver, but for some other use, we can still do
it. Next, consolidate all of these into the single entry in
drivers/serial/Kconfig. Finally, introduce CONS_INDEX_[023456] so that
we can imply a correct value here to make the defconfig side of this
smaller.

The goal of this patch is to clean up the code related to choosing SPL
MMC boot mode.
The spl_boot_mode() now is called only in spl_mmc_load_image() function,
which is only compiled in if CONFIG_SPL_MMC_SUPPORT is enabled.
To achieve the goal, all per mach/arch implementations eligible for
unification has been replaced with one __weak implementation.

All the new SoCs from Allwinner since the A33 have had the phy_ctl offset
at 0x410 instead of 0x404 that was used on the previous SoCs.
Instead of adding more and more special cases as the number of SoCs grow,
let's invert the test to have 0x410 by default, and the (hopefully) fixed
number of old SoCs being the exception.

At present we support multiple environment drivers but there is not way to
select between them at run time. Also settings related to the position and
size of the environment area are global (i.e. apply to all locations).
Until these limitations are removed we cannot really support more than one
environment location. Adjust the location to be a choice so that only one
can be selected. By default the environment is 'nowhere', meaning that the
environment exists only in memory and cannot be saved.
Also expand the help for the 'nowhere' option and move it to the top since
it is the default.

With SPL_LDSCRIPT moved to Kconfig (and this being a 'string' config
node), all the lingering definitions in header files will cause
warnings/errors due to the redefinition of the configuration item.
As we don't want to pollute the defconfig files (and values should
usually be identical for entire architectures), the defaults are moved
into Kconfig. Kconfig will always pick the first default that
matches, so please keep these values at the end of each file (to allow
any board-specific Kconfig, which will be included earlier) to
override with an unconditional default setting.

This converts the following to Kconfig:
CONFIG_ENV_IS_IN_MMC
CONFIG_ENV_IS_IN_NAND
CONFIG_ENV_IS_IN_UBI
CONFIG_ENV_IS_NOWHERE
In fact this already exists for sunxi as a 'choice' config. However not
all the choices are available in Kconfig yet so we cannot use that. It
would lead to more than one option being set.
In addition, one purpose of this series is to allow the environment to be
stored in more than one place. So the existing choice is converted to a
normal config allowing each option to be set independently.
There are not many opportunities for Kconfig updates to reduce the size of
this patch. This was tested with
./tools/moveconfig.py -i CONFIG_ENV_IS_IN_MMC
And then manual updates. This is because for CHAIN_OF_TRUST boards they
can only have ENV_IS_NOWHERE set, so we enforce that via Kconfig logic
now.

The DesignWare-like DRAM code used to set the controller defaultly to
single rank mode, which makes it not able to detect the second rank.
Set the default value to dual rank, thus the rank detection code can
work and finally the rank setting will be the correct value.
Currently we know little about the dual-rank on R40, and the usage
of A15 address line seems to be breaking dual-rank support. The only R40
board currently available (Sinovoip Banana Pi M2 Ultra) uses A15 rather
than dual-rank, thus we cannot do research for it. So dual rank detection
is temporarily disabled on R40.
This change is tested on a Orange Pi One (H3, single rank), a Pine64+
2GiB version (A64, single rank) , a Pinebook early prototype with DDR3
(A64, dual rank) and a SoPine with some LPDDR3 patch (A64, dual CS pins
on one chip).

The DesignWare DRAM controller used by H3 and newer SoCs use a bit to
identify whether the DRAM is half-width.
As H3 itself come with 32-bit DRAM, the two modes of the bit used to be

they're really 8-bit and 16-bit.

This commit adds support for DM I2C on sunxi platform. It can coexist
with old style sunxi I2C driver, because it is still used in SPL and
by some SoCs.
Because sunxi platform doesn't yet support DM clk, reset and pinctrl
driver, workaround is needed to enable clocks and set resets and
pinctrls. This is done by calling i2c_init_board() in board_init().
This means that CONFIG_I2Cx_ENABLE options needs to be correctly set
in order to use needed I2C controller.
