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
option on SoCs that don't have the DesignWare SPI HW.
This commit hides the driver by default by introducing the config
option HAS_SPI_DW.

This patch adds a flash driver for the Atmel SAM E70 SoC. The driver has
been kept simple by considering that the flash is only composed of 8-KiB
blocks. Indeed an area at the beginning of the flash might be erased
with a smaller granularity, and the other blocks can also be erased with
a higher granularity. It also only handles the global read/write
protection, not the 128-KiB lock regions. A write error is returned if
a region is locked.

When the WNC-14A2A modem binding was originally introduced, I thought
the base_label would shorten the define keeping the result short and
easily portable. Turns out with the latest changes, it has a side
effect of removing the "DT_*" prefix which is breaking the build.
Let's remove "base_label" from the modem binding and adjust all of
the dts_fixups referring to the WNC14A2A defines.
NOTE: This commit moves the left-over WNC14A2A dts_fixup defines from
the nRF52 soc into samples/net/lwm2m_client as the new values.
They will stay there until the modem can be re-configured as a shield.

The firmware starts us with an already-initialized UART and a simple

This can help find unused symbols. Those end up without a type if
'default' is used instead of 'def_bool', which generates a warning.
Search for "Kconfig.defconfig" in
https://docs.zephyrproject.org/latest/application/kconfig-tips.html for
a longer explanation.
Keep the 'def_bool' for the following symbols, which seem to be
deliberately defined only in Kconfig.defconfig files:
- ALTERA_AVALON_I2C
- ALTERA_AVALON_MSGDMA
- ALTERA_AVALON_PIO
- ALTERA_AVALON_QSPI
- ALTERA_AVALON_SYSID
- CLOCK_CONTROL_IMX_CCM
- CPU_EM4_DMIPS
- CPU_EM4_FPUDA
- CPU_EM4_FPUS

These changes were obtained by running a script created by
Ulf Magnusson <Ulf.Magnusson@nordicsemi.no> for the following
specification:
1. Read the contents of all dts_fixup.h files in Zephyr
2. Check the left-hand side of the #define macros (i.e. the X in
#define X Y)
3. Check if that name is also the name of a Kconfig option
3.a If it is, then do nothing
3.b If it is not, then replace CONFIG_ with DT_ or add DT_ if it
has neither of these two prefixes
4. Replace the use of the changed #define in the code itself
(.c, .h, .ld)
Additionally, some tweaks had to be added to this script to catch some
of the macros used in the code in a parameterized form, e.g.:
- CONFIG_GPIO_STM32_GPIO##__SUFFIX##_BASE_ADDRESS
- CONFIG_UART_##idx##_TX_PIN
- I2C_SBCON_##_num##_BASE_ADDR
and to prevent adding DT_ prefix to the following symbols:
- FLASH_START
- FLASH_SIZE
- SRAM_START
- SRAM_SIZE
- _ROM_ADDR
- _ROM_SIZE
- _RAM_ADDR
- _RAM_SIZE
which are surprisingly also defined in some dts_fixup.h files.
Finally, some manual corrections had to be done as well:
- name##_IRQ -> DT_##name##_IRQ in uart_stm32.c
