There are a few different places where alternatives for setting
environment variables are described. None of them is 100% complete, so
the results are likely to be confusing.
Make a single page on setting environment variables, how the zephyrrc
files work, how the zephyr-env scripts work, and some of the important
environment variables, with appropriate references elsewhere. (This is
inspired by the Arch wiki's excellent page on installing programs.)
Link to it from the getting started and application development pages
instead of repeating the information. This has the benefit of
shortening the getting started guide a bit more.
Add some concrete advice on checking the toolchain environment
variables in particular. This is a stumbling block for beginners.

Updates based on discussion and changes in supported features.
- Make the guide shorter by removing content that's not relevant to
most users who are truly just getting started, such as information
about pre-LTS versions that did not support west, and by being more
concise in some places.
- Decrease the number of colored boxes. At the latest TSC F2F, the
"note / warning / note / tip" contents were identified as a
readability problem.
- Add additional information based on new west features, like "west
boards".

The k_stack data type cannot be u32_t on a 64-bit system as it is
often used to store pointers. Let's define a dedicated type for stack
data values, namely stack_data_t, which can be adjusted accordingly.
For now it is defined to uintptr_t which is the integer type large
enough to hold a pointer, meaning it is equivalent to u32_t on 32-bit
systems and u64_t on 64-bit systems.

On 64-bit systems the most notable difference is due to longs and
pointers being 64-bit wide. Therefore there must be a distinction
between ints and longs.
This patch:
- Make support functions take a long rather than an int as this can
carry both longs and ints just fine.
- Use unsigned values in _to_x() to cover the full unsigned range
and avoid sign-extending big values. Negative values are already
converted to unsigned after printing the minus sign. This also makes
division and modulus operations slightly faster.
- Remove excessive casts around va_arg() and use proper types with it.
- Implement the l and z length modifiers as they're significant on
64-bit targets. While at it, throw in the z modifier as well.
Since they all come down to 32-bit values on 32-bit targets, the
added code should get optimized away as duplicate by the compiler
in that case.

Because of how generate defines for instances its possible that we have
a name conflict if the instance ID and reg addr space clash.
For example on qemu_x86 there are current two 'soc-nv-flash' nodes and
one is at reg addr 0, but instance id 1, the other is reg addr 0x1000
and instance id 0. We'd possibly get this conflict:
For the 'soc-nv-flash' at 0x1000 (instance 0):
(instance define)
#define DT_SOC_NV_FLASH_0_BASE_ADDRESS 0x1000
For the 'soc-nv-flash' at 0x0 (instance 1):
(address define)
#define DT_SOC_NV_FLASH_0_BASE_ADDRESS 0x0
To deal with this we make sure that the lower reg address is instance 0,
than things work out ok. To handle this case, if we sort the instance
IDs based on reg addr than if we have something at reg addr 0, it will
also than be an instand ID 0.
The longer term solution will be to deprecated the old defines and
remove the conflict between instance ID defines and normal DT defines.

Using void pointers as universal arguments is widely used. However, when
compiling a 64-bit target, the compiler doesn't like when an int is
converted to a pointer and vice versa despite the presence of a cast.
This is due to a width mismatch between ints (32 bits) and pointers
(64 bits). The trick is to cast to a widening integer type such as
intptr_t and then cast to
void*.
When appropriate, the INT_TO_POINTER macro is used instead of this
double cast to make things clearer. The converse with POINTER_TO_INT
is also done which also serves as good code annotations.
While at it, remove unneeded casts to specific pointer types from void*
in the vicinity, and move to typed variable upon function entry to make
the code cleaner.
Signed-off-by: Nicolas Pitre <npitre@baylibre.com>
The INT_TO_POINTER and POINTER_TO_INT macros must accommodate larger
pointers on 64-bit systems that don't fit into an int.
In the INT_TO_POINTER case, we have to use an extra cast to intptr_t
as an intermediate widening type to avoid complaints from the compiler
when converting from an int.
This change makes no difference on 32-bit systems.
