8defb843aa Remove duplicate linker script definitions
## Summary
A lot of linker scripts were listed twice, once for unix, once for windows.

This PR cleans up the logic so they're only listed once.

 ## Impact
Any opportunity to use a single source of truth and reduce lines of code is a win!

 ## Testing
CI will test all build

This reverts commit 45672c269d.

Because:

* It's very confusing to have cc as LD.
* I don't see what "-nostartfiles -nodefaultlibs" in LDFLAGS are
  supposed to do when we use LD directly. It would be simpler to
  remove them from our LDFLAGS.

6c2c70c61e Make: fix use of gcc as LD for modules and ELF executables builds
The patch

  Make: use gcc as LD

introduced use of GCC wrapper as linker. LD variable references GCC
executable now. But when GCC wrapper s used to build relocatable
loadable objects (ELF executables and modules) then it causes
linking of toolchain default libc and other libraries even when -r
is usd. Another problem is that incorrect multiarch variant is selected
for libraries search and possibly even for LTO or C++ templates
instantiating and other glue code which causes fails during linking
if CFLAGS selects non/default miltiarch variant.

Corresponding CFLAGS are passed to LDMODULEFLAGS and LDELFFLAGS
as well as -nostartfiles -nodefaultlibs options.

Separate line is used to easily find and adjust lines if link
process is changed in future.

4716fc929d arch/stm32h7 - Fix HEAP clobbering static data in SRAM4
Normally, statically allocated data goes in .bss, followed by the
initial stack, followed by HEAP. However, any data that is statically
allocated in SRAM4 with __attribute__ ((section (".sram4"))) will
clobber, and be clobbered by, the HEAP.

On STM32H7, BDMA can only access SRAM4. Therefore any BDMA buffers (or
any other data) placed in SRAM4 will expose this problem. In one case,
this manifested as a failure of NSH to start, because the SPI6 BDMA
buffers clobbered the /dev/console inode structs, which the OS
allocated earlier.

This PR ensures that only the rest of SRAM4, after any static data, is
added to the heap. This PR also allows SRAM4 to be completely excluded
from the heap by a new Kconfig, CONFIG_STM32H7_SRAM4EXCLUDE, similar
to what CONFIG_STM32H7_DTCMEXCLUDE does for the DTCM region.

Change required in linker scripts:

Every STM32H7 linker script must replace this:

    .sram4 :
    {
    } > sram4

with this:

    .sram4_reserve (NOLOAD) :
    {
        *(.sram4)
        . = ALIGN(4);
        _sram4_heap_start = ABSOLUTE(.);
    } > sram4

or link will fail with: undefined reference to '_sram4_heap_start'.

The Release Notes should document this for users with out-of-tree
boards.

arch/arm/src/stm32h7/Kconfig:

    * Add config STM32H7_SRAM4EXCLUDE to allow excluding all of SRAM4
      from the HEAP.

arch/arm/src/stm32h7/stm32_allocateheap.c:

    * Only when including SRAM4 in the heap, define HAVE_SRAM4,
      SRAM4_START, SRAM4_END, and SRAM4_HEAP_START.

    * Add "Private Data" section.

    * Add extern for_sram4_heap_start, which must be defined in the
      board's linker script.

    * arm_addregion(): Only add SRAM4 to the heap when configured to
      do so, i.e., unless CONFIG_STM32H7_SRAM4EXCLUDE is defined, and
      only add the portion of SRAM4 that is past any static data.

b88561299b make/expression: improving up asm/C/C++ compile times
In the current compilation environment, the recursive assignment(=) for compile
flags will be delayed until every file is actually need to be compile.

For example:
--------------------------------------------------------------------------------
arch/arm/src/Makefile:

INCLUDES += ${shell $(INCDIR) "$(CC)" $(ARCH_SRCDIR)$(DELIM)chip}
INCLUDES += ${shell $(INCDIR) "$(CC)" $(ARCH_SRCDIR)$(DELIM)common}
INCLUDES += ${shell $(INCDIR) "$(CC)" $(ARCH_SRCDIR)$(DELIM)$(ARCH_SUBDIR)}
INCLUDES += ${shell $(INCDIR) "$(CC)" $(TOPDIR)$(DELIM)sched}

CPPFLAGS += $(INCLUDES) $(EXTRAFLAGS)
CFLAGS += $(INCLUDES) $(EXTRAFLAGS)
CXXFLAGS += $(INCLUDES) $(EXTRAFLAGS)
AFLAGS += $(INCLUDES) $(EXTRAFLAGS)
--------------------------------------------------------------------------------

All compilation options will be included recursively,
which will be delayed until the compilation options are actually used:

tools/Config.mk:

--------------------------------------------------------------------------------
define COMPILE
  @echo "CC: $1"
  $(Q) $(CC) -c $(CFLAGS) $($(strip $1)_CFLAGS) $1 -o $2
endef
--------------------------------------------------------------------------------

All compile flags to be reexecuted $(INCDIR) as long as one file needs to be compiled,
but in fact, the compilation options have not changed in the current directory.

So the we recommand to change the syntax of assignment
From
    Recursive (=)
To
    Simple    (:=)

In this way, we can ensure that all compilation options are expanded only once and reducing repeated works.

037c9ea0a4 arch/arm: Rename all up_*.h files to arm_*.h
Summary

The naming standard at https://cwiki.apache.org/confluence/display/NUTTX/Naming+FAQ requires that all MCU-private files begin with the name of the architecture, not up_.

This PR addresses only these name changes for the up_*.h files.  There are only three, but almost 1680 files that include them:

    up_arch.h
    up_internal.h
    up_vfork.h

The only change to the files is from including up_arch.h to arm_arch.h (for example).

The entire job required to be compatible with that Naming Convention will also require changing the naming of the up_() functions that are used only within arch/arm and board/arm.

Impact

There should be not impact of this change (other that one step toward more consistent naming).

boards: add stub drivers folder for later use

* boards: add stub drivers folder for later use

    The board/drivers folder is added for future use.

    In this folder we should place drives that are platform specific and
    depend on HW that is present only on a specific platform.

    NOTE: All shared drivers should go to the regular driver folder

* tools: shift BOARD_DIR one level up

    In preparation for drivers and common folders we are moving the
    BOARD_DIR path up one level.

* tools: add drivers/platform symlink

    Link the boards/<arch>/<chip>/drivers dir to drivers/platform

    Signed-off-by: Alin Jerpelea <alin.jerpelea@sony.com>

* drivers: add platform specifc drivers extension

    There are platforms that use specific drivers and we should be able to
    include those drivers in the build

* board: cxd56xx: drivers: add AK09912 driver for SCU

    This is a platform specific driver connected on the SCU unit.

stm32h7 RTC and friends  support

* stm32h7:Removed f7 in file path

* stm32f7:Fix overwritten IRQ enabled

       System boot order calls clock_initialize then up_initalize.
       clock_initialize was setting up the alarm IRQ
       up_initalize is initializing the NVIC.

       This most likely worked in the past due to a bug in the
       NVIC init code that failed to clear the Interrupt enables.
       That was fixed in 510b0f7e arch/arm/src: Correct all ARMv7-M
       architectures.  Interrupts were not be disabled correctly
       on power up.

* stm32h7:Ported over F7 RTC

* nucleo-h743zi:Add RTC
