90c73e3e5a scripts/dts: Rename extract_node_include_info()
...to generate_node_defines().

More explicit. "extract node include info" can be read in many ways:

 - Extract a node's "include info"

 - Extract node and include info

 - etc.

35b3d440c1 scripts/dts: Replace the Bindings class with plain functions
The Bindings class was only used to implement '!include foo.yaml'
(easier to see after some things were moved out of it). Use plain
functions instead, which might be a bit more transparent and gives
simpler code.

Also remove the recursive '!include' detection for now, which is broken
in that the same .yaml being included twice will always trigger it, even
for non-circular cases.

4a99dbcf9e scripts/dts: Simplify and remove dead code in Bindings._extract_file()
As written, this function could take e.g. '!include bar', find 'foo-bar'
(due to the endswith()), and include it. This is undocumented and
doesn't seem to be used, so I'm guessing that it isn't intentional.

Removing that bug/feature also makes the code much simpler.

DT_FLASH_AREA_<X>_DEV should be the label of the flash controller.  For

b278500d94 scripts/dts: Remove dead and confusing pwm/gpio-related code
- Maybe the code is trying to turn integers into single-element list,
   but it won't work (needs to be [value] rather than list(value)).
   Don't think you could ever end up with an integer either.

 - extract_controller() assumes that prop_values is a list, so

d26cb1fb55 scripts/dts: Remove redundant and confusing dict.get() calls
dict.get(key) signals to people reading the code that you're not sure
whether the key exists. It returns None if it doesn't.

When the key is known to exist, dict[key] should be used. This also
helps catch bugs by raising an exception if the key is missing.

Similarly, whether a key in a dict should be tested with

    if key in dict:

instead of with

    if dict.get(key):

The second version signals that you both want to make sure that the
exists and that it's truthy (e.g., non-empty). That's confusing if a
simple existence check was meant.

There seems to be a bug in output_keyvalue_lines() where

    fd.write("%s=%s\n" % (entry, defs[node].get(a)))

can end up writing '...=None'. Removing the .get() makes it throw an
exception instead. Keep the .get() for now and don't attempt to fix the
bug.

87915cd36f dts: stop generating CONFIG_FLASH_LOAD_{OFFSET,SIZE}
As a step to completing removing use of Kconfig defines in dts files we
need to change how we configure/set CONFIG_FLASH_LOAD_{OFFSET,SIZE}.

Previously we would set them based on how the chosen property
'zephyr,code-partition' was set to.  If 'zephyr,code-partition' wasn't
set we would default the values to 0.  We had some generic overlay logic
which would define 'zephyr,code-partition' based on
CONFIG_BOOTLOADER_MCUBOOT.

Going forward if the DTS has 'zephyr,code-partition' set we will
generate DT_CODE_PARTITION_OFFSET & DT_CODE_PARTITION_SIZE defines.  We
will leave it to Kconfig to set CONFIG_FLASH_LOAD_OFFSET &
CONFIG_FLASH_LOAD_SIZE.

We introduce a python script that allows Kconfig to extract data from
the DTS and thus we can utilize DT_CODE_PARTITION_OFFSET and
DT_CODE_PARTITION_SIZE values to set defaults for
CONFIG_FLASH_LOAD_OFFSET & CONFIG_FLASH_LOAD_SIZE.

c23cc26c73 DeviceTree: Convert 'generated_dts_board.h' into a source file
extract_dts_includes.py has been generating DT output and then
concatenating it with fixup header files to create
'generated_dts_board.h'.

In this patch we instead introduce a source file named
'generated_dts_board.h' and have it \#include the appropriate DT
output and fixup files.

This results in a simpler system because users can now read
'generated_dts_board.h' as C source code to see how fixup files and
generated DT output relate to each other. Whereas before they would
have to either read documentation or python code to gain the same
understanding.

Also, it reduces the scope and complexity of one of our most bloated
python scripts, extract_dts_includes.py.

The Intel S1000 board has a SPI flash that isn't directly MMIO
addressable.  For this case we shouldn't generate CONFIG_FLASH_SIZE or

We use the heuristic of assuming if the flash node #size-cells is 0, its
a SPI flash.  Than if the parent node (SPI controller) has only a single
reg element we assume its a non-MMIO addressable SPI flash.  If there is
more than one reg element we assume the last reg element is the MMIO
address region for access to the flash.

e57a596a0c scripts/dts/extract: Support QSPI memory mapped flash
We need to refactor how we determine CONFIG_FLASH_{SIZE,BASE_ADDRESS}
for when we have a QSPI that is memory mapped. "zephyr,flash" is going
to point the actual flash component that will be on a SPI bus and thus
the device node's reg property tells us which CS on the SPI bus its on,
not the memory mapped address/size of the flash.

So we make a few assumptions to handle this case:
1. If the #size-cells for the flash node is 0, we assume its a QSPI
   memory mapped flash
2. That the QSPI memory mapped node (parent of what "zephyr,flash" is
   point to, will contain a reg propery where the second reg pair will
   be the memory mapped region for the flash.

We move handling of CONFIG_FLASH_{SIZE,BASE_ADDRESS} into flash.extract
so its all in one place.

471d2f3a0a scripts: extract_dts_includes: Generate device bus info define
For devices on buses like I2C or SPI its possible that a sensor might
support being on either bus type.  In the dts we can tell this by
looking at the parent bus of the device.  Its useful for a driver to
know this so can we build support into the driver accordingly.

For example if the LSM6DSL sensor ("st,lsm6dsl") is in the dts on a spi
bus we now generate:

	#define DT_ST_LPS22HB_PRESS_BUS_SPI	1

Its possible that a system exists in which multiple of the same sensor
exist but on different busses, so drivers should handle that case
accordingly.  For the LSM6DSL example we'd end up with:

	#define DT_ST_LPS22HB_PRESS_BUS_I2C	1
	#define DT_ST_LPS22HB_PRESS_BUS_SPI	1

now support having two different binding files for the same compatiable
to handle the case of a sensor supporting either I2C or SPI as how its
connected.

We put "sensor" nodes in a bus specific dict bus_bindings[bus] that
we can than lookup later based on the DTS and determining the bus type
that the "sensor" node is on.

fc5e23365e dts: Add proper handling for boolean properties
We've never handled boolean properties well, if we had a boolean that
existed we'd generate a define of 'True' and if the boolean didn't exist
than nothing would be generated.  So there was no easy way to tell that
the boolean wasn't defined.

Now if we mark a property as boolean in the yaml, we will generate a
define for it regardless if it exists or not.  If it exists we'll
set the value to 1, and if it doesn't to 0.

Fixes #8376

After dtc 1.4.7 we get:

the property.

may vary from system to system (e.g. LOCALE=C aka "ascii" on bare-OS

typically used one address spaces translate from one physical bus to
another (For example going from PCI address space to internal SoC memory
map).  However, we can also use this for cases where we want to reduce
duplication (For example with ARMv8-M for secure v non-secure MMIO
registers).

'ranges' takes either the form of:
	ranges; /* pass through translation */
or:
	ranges = <child-bus-address parent-bus-address length>;
