Currently CPU_V7 kconfig symbol supports only ARMv7A architectures under
armv7 folder. This led to a misconception of creating separate folders
for armv7m and armv7r. There is no reason to create separate folder for
other armv7 based architectures when it can co-exist with few Kconfig
symbols.
As a first step towards a common folder, rename CPU_V7 as CPUV7A. Later
separate Kconfig symbols can be added for CPU_V7R and CPU_V7M and
can co exist in the same folder.

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.

Enable uart overrun feature which allows to benefits of uart
FIFO usage.
Previously overrun management was disabled, this has to effect
to bypassed the uart FIFO usage even if FIFO was enabled.
In particular configuration, for example when video console is
enabled, copy/pasting a long command line in console results in
corruption. This is due to the fact that a lot of time is consumed
in flushing the cache during frame buffer update, so uart chars are
not read fast enough.
By using uart FIFO and managing overrun, long command line can by
copy/paste in console without being corrupted.

This patch fixes a situation where CONFIG_DM_SERIAL is enabled for
regular U-Boot and SPL, but not for TPL. In that case, the build
will try to include serial-uclass into the TPL nonetheless, because
CONFIG_DM_SERIAL is set.
The solution is to check if the build is for SPL or TPL and in that
case, check if CONFIG_$(SPL_TPL_)DM_SERIAL is also set. Only in that
case, include serial-uclass.c . If the build is for regular U-Boot,
CONFIG_BUILD is not set, so only check if CONFIG_DM_SERIAL is set
and if so, include serial-uclass.c

This converts the following to Kconfig:

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

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.

This header includes things that are needed to make driver build. Adjust
existing users to include that always, even if other dm/ includes are
present

It's currently bugged and doesn't work for even cases.
Right shift bits instead of dividing and fix even cases.

I missed this when I added support for BMIPS UART driver and it's needed to
achieve a real 115200 8N1 setup.

On my x86 platform I've noticed, that calling dm_uninit() or the new
function dm_remove_devices_flags() does not remove the desired device at
all. Debugging showed, that the serial uclass returns -EPERM in
serial_pre_remove(). This patch sets the force parameter when calling
stdio_deregister_dev() resulting in a removal of the device.
