The original em7d, em9d and em11d are different configurations of
em_starterkit. They have the same peripherals, e.g. uart, spi, gpio
, ddr. The differences of them are in arc core configurations, interrupt
number assignment.
So em7d, em9d and em11d can be viewed in the same SoC family or SoC
series.
Referring other arch's implementation, this commit merges em7d, em9d
and em11d into the same SoC, named snps_emsk. This will eliminate
unnecessary duplication and make it easier for future maintainment.

MPU devices that enforce power-of-two alignment now
specify the size of the buffer used for the newlib heap.
This buffer will be properly aligned and a pointer
exposed in a kernel header, such that it can be added
to a user thread's memory domain configuration if
necessary.
MPU devices that don't have these restrictions allocate
the heap as normal.
In all cases, if an MPU/MMU region needs to be programmed,
the z_newlib_get_heap_bounds() API will return the necessary
information.
Given how precious MPU regions are, no automatic programming
of the MPU is done; applications will need to do this as
needed in their memory domain configurations.
On x86, the x86 MMU-specific code has been moved to arch/x86
using the new z_newlib_get_heap_bounds() API.

Adds dts bindings for the mcr20a wireless transceiver. The frdm_k64f
board supports the mcr20a via an Arduino shield, therefore the dts node
is added to the board dts. The kw2xd is a SiP and thus the mcr20a dts
node is added to the soc dts.
The networking samples using prj_frdm_k64f_mcr20a.conf have been broken
since the refactoring of the mcux gpio driver to dts in commit
4e8f29f319. The sample is now fixed.

When we included SoC specific Kconfig files we do something like:
gsource "arch/arm/soc/arm/*/Kconfig.soc"
However, we should do that inside an if block for that SoC family so as
to limit SoC family specific options to only being visible when that SoC
family is selected. So we simply move the gsource and related items
inside the if SOC_FAMILY_<SOC> block.

In dts.fixup files for used for NXP SoCs, IP clock name was
bound to SIM clock label. This is correct but would require
manual change if IP clock controller was changed in device tree.
Use reference to IP generated define "_CLOCK_CONTROLLER" to get
this value.
Besides, having all IP related values starting with the same prefix
will be easier for possible macro preprocessing (if required one day).

'cell_string' yaml attribute has been introduced in order to
help enforcement of specific string during defines generation.
This adds complexity in understanding script behavior as a black
box and create additional dependency which is not strictly required.
For node specific generation functions (pinctrl and interrupts),
this could be replaced directly by an hardcoded version
(as everyone used the same 'cell_string' anyway).
For extract_cells functions, string could be replaced by extracted
property name. As a consequence, we're now able to generate defines
for properties refering to these controllers via phandle.
For instance, in following node
spbtle-rf@0 {
compatible = "st,spbtle-rf";
reg = <0>;
reset-gpios = <&gpioa 8 0>;
};
We'll be able to generate:
#define ST_STM32_SPI_...LE_RF_0_RESET_GPIOS_CONTROLLER "GPIOA"
#define ST_STM32_SPI_...PBTLE_RF_0_RESET_GPIOS_FLAGS_0 0
#define ST_STM32_SPI_..._SPBTLE_RF_0_RESET_GPIOS_PIN_0 8
Only impact for this whole change is for NXP clocks which were the
only ones using 'cell_string' attribute with a value different than
the default one.

Indexed defines were systematically generated even when there
was only one element to generate.
So we ended up generated a lot of _0 defines.
Then we needed to generate aliases to these _0 indexed defines,
in order to get useful defines.
For instance:
#define GPIO_LEDS_0_GPIO_FLAGS_0 4
#define GPIO_LEDS_0_GPIO_PIN_0 5
#define GPIO_LEDS_0_GPIO_FLAGS GPIO_LEDS_0_GPIO_FLAGS_0
#define GPIO_LEDS_0_GPIO_PIN GPIO_LEDS_0_GPIO_PIN_0
This commit allows to generate _0 indexed define only if a
property has more than one elements to define.
Aliases generation to _0 indexed defines are also removed.
Note: IRQ are left untouched since this is frequent to handle
multiple IRQs in a driver

The loop that checks the MPU region permissions incorrectly
iterates from (num_region + 1) to 1. This should be
(num_region - 1) to 0. This results in the wrong regions
being checked and possible overflow for any implementation

Until now, Zephyr has used a patched Kconfiglib that turns 'source' into
a globbing source (by replacing 'source' with 'gsource' at the token
level). There's two problems with this:
- The patch needs to be maintained separately
- Misspelled filenames are silently ignored, as they look like glob
patterns that don't match anything
Fix it as follows:
1. Replace all 'source' statements that use wildcards with 'gsource'
2. Remove the custom Kconfiglib patch so that 'source' no longer globs
The sed pattern '/source.*[*?]/s/source/gsource/' was run over all
Kconfig* files to do the replacement.
source's that use environment variables that might contain glob patterns
were manually changed to gsource.
Building the docs in doc/ is a good test, as doc/Makefile deliberately
sets the environment variables to glob up as many Kconfig files as
possible.
