The early boot watchdog init for kinetis was incorrectly disabling and
reenabling interrupts to preserve timing during the unlock sequence.
However, interrupts are already disabled before this routine executes
and the kernel is not yet ready to enable them when this routine exits.

This patch adds a flash driver for the STM32F7x series, inspired from
the STM32F4x one. It has been tested on the STM32F723, but should also
work on other SoCs of the family.

This commit simplifies Kconfig options related to handling SoC series,
part numbers. This is a first step required to add remaining part
numbers to the existing configuration.
This change is possible since all SiLabs SoCs within a single series
have a very uniform structure.

All text, data and bss sections are all mapped to the same physical
memory (SRAM). This patch removes the individual section limits
and defines a common limit for the sum of text, data and bss sections.
This would make it more flexible for application developers.
Fixes#11268.

CONFIG_TEXT_SECTION_OFFSET allows the entire image to be moved
in memory to allow space for some type of header. The mcubootloader
can boot only such images which reserve some space for the header.

RISC-V permits myriad extensions to the ISA, any of which may imply
additional context that must be saved and restored on ISR entry and
exit. The current in-tree example is the Pulpino core, which has extra
registers used by ISA extensions for running loops that shouldn't get
clobbered by an ISR.
This is currently supported by including pulpino-specific definitions
in the generic architecture code. This works, but it's a bit inelegant
and is something of a layering violation. A more generic mechanism is
required to support other RISC-V SoCs with similar requirements
without cluttering the arch code too much.
Provide that by extending the semantics of the existing
CONFIG_RISCV_SOC_CONTEXT_SAVE option to allow other SoCs to allocate
space for saving and restoring their own state, promoting the
currently pulpino-specific __soc_save_context / __soc_restore_context
routines to a RISC-V arch API.
The cost of making this generic is two more instructions in each ISR
to pass the SoC specific context to these routines in a0 rather than
just assuming the stack points to the right place. This is minimal,
and should have been done anyway to keep with the ABI.
As a first (and currently only in-tree) customer, convert the Pulpino
SoC code to this new mechanism.

The driver can be tested using different networking emulation
approaches.
This approach will work across multiple Qemu instances. There can be
more than one Qemu instance, run using the following command. They
would appear to be on the same Ethernet network.
$ qemu-system-arm -M lm3s6965evb \
-serial stdio \
-net nic \
-net socket,mcast=230.0.0.1:1234 \
-kernel zephyr.elf
This approach will work with other virtualization technologies that
support connecting to a VDE switch, like VirtualBox and User Mode
Linux. The switch can be started using the following command.
$ vde_switch --sock /tmp/switch
Qemu can be connected to the switch using the following command.
$ qemu-system-arm -M lm3s6965evb \
-serial stdio \
-net nic \
-net vde,sock=/tmp/switch \
-kernel zephyr.elf

Within a single series pin mapping between location setting and pin name
is uniform. The only difference is availability of the module, i.e. i2c1
may be missing on some part numbers, or availability of the pin, i.e.
32 pin package will not provide all the pins available on 48 pin
package. It's better to manage these differences at the DTS/Kconfig
level.
This commit removes dependency of soc_pinmap.h files on part numbers.

Implementation taken from Nordic nrfx version 1.3.1 soc/nrfx_coredep.h,
modified to remove material from other series and to conform to Zephyr
coding standards.
Note that unlike standard k_busy_wait this is susceptible to
longer-than-intended delays due to the impact of interrupt handling.

The Cortex-M7 CPU included in the SAM e70 SoCs has a data cache that
significantly boost the performances. However the SAM GMAC Ethernet
driver is using a scatter-gather technique to exchange data with the
Ethernet driver. This requires the use use of a non-cached memory area.
This is currently not supported on Zephyr, but support for it is being
discussed in PR#11199.
In the meantime, enable the data cache during the SoC initialization,
unless the SAM GMAC Ethernet driver is enabled.

When users are configuring applications they are given the option
to enable the DesignWare SPI driver. But they should not be given this
