- migrated /README are removed from /boards
- there are a lot of READMEs that should be further converted to rst.
At the moment they are moved to Documentation/platforms and included in rst files

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.

from 1 to 2 oherwise pthread_condclockwait will fail

1. Add missing conditional logic in include/sys/syscall_lookup.h
2. CONFIG_NPTHREAD_KEYS removed from code but was still in sched/Kconfig
3. Refresh all configurations affected by PR 1007
4. syscall/syscall_funclookup.c needs to include nuttx/tls.h
1. Move pthread-specific data files from sched/pthread/ to libs/libc/pthread.
2. Remove pthread-specific data functions from syscalls.
3. Implement tls_alloc() and tls_free() with system calls.
4. Reimplement pthread_key_create() and pthread_key_free() using tls_alloc() and tls_free().
5. Reimplement pthread_set_specific() and pthread_get_specicif() using tls_set_value() and tls_get_value()
So call 'make EXTRAFLAGS=-Wno-cpp' could suppress the warnings with pre-processor
directive #warning in GCC.

* tools/Config.mk - Add empty definition POSTBUILD
* tools/Makefile.unix/win - Replace CXD56xx specific logic with $(call POSTBUILD)
* boards/arm/cxd56xx/scripts/Config.mk - Add POSTBUILD definitions with logic removed from Makefile.unix/win
* boards/arm/cxd56xx/spresense/scripts/Make.defs - Include the CXD56xx Config.mk immediately after tools/Config.mk so that the empty POSTBUILD definition will be replaced with the correct one
NOTE: There is a precedent for this approach. This is the way that other architecture-specific build options are implemented. See, for example, tools/zds/Config.mk
Kconfig files. Repartition some functionality. Bootloader support will need to be provided in logic under arch/z80/src/ez80 so the critical configuration selections were moved the Kconfig file there.
arch/z80/src/ez80/ez80_i2c.h: Rename arch/z80/src/ez80/ez80f91_i2c.h. It is sharable by both ez80f91 and ez80f92.
arch/z80/src/ez80/: Add logic to perform an additional level of interrupt redirection. This is necessary because the the interrupt handling is part of the loader FLASH-based logic. In order to share interrupts with the program loaded into RAM by the loader, another layer or redirection is required to get control to the interrupt handlers in the loaded program. See ez809f2_loader.asm and ez80f92_program.asm
boards/z80/ez80/z20x/scripts: Reduce size of the interrupt re-direction buffer from 1Kb to 512b.
board/z80/ez80/*/scripts/Make.defs: Fix optimization definition use in assembly flags. It was using the compiler optimization settings instead of the assembler optimization settings. Hence, enabling optimization would could cause assembler command line errors.
arch/z80/src/ez80/Toolchain.defs: Back out some work arounds. Now compiler optimization flags can again set set without assembler command line errors.
boards/z80/ez80/z20x/README.txt: Trivial update to size/optimization discussion.
arch/z80/src/ez80/Toolchain.defs: Correct some CFLAGS when optimization suppressed.
arch/z80/src/ez80/Kconfig arch/z80/src/ez80/ez80_emac.c: Remove configuration option for selecting EMAC RAM address. This is duplicated and possibly conflicting. The correct address for the RAM is provided in the linker command file. The RAM should be configured once and using this single definitions.
arch/z80/src/ez80/ez80_startup.asm and arch/z80/src/ez80/ez80f9*_init.asm. Move RAM and FLAH intialization out of MCU-specific logic to common start-up logic. We cannot call any functions until SRAM is initialized and the stack is properly initialized because the return address is stored on the stack. Use internal SRAM for the IDLE stack to avoid the chicken'n'egg problem.
boards/z80/ez80/z20x/configs/sdboot/sdboot.zdsproj: Discuss build environments.
arch/z80/src/ez80/Toolchain.defs: Update some CFLAGS to match CFLAGS from ZDS-II IDE. Apparently, we must say that the CPU is an eZ80F91 event when compiler for eZ80F92.
boards/z80/ez80/z20x: Update linker scripts.
* tools/zds/zds_Config.mk: Move boards/z80/ez80/scripts/eZ80_Config.mk to tools/zds/zds_Config.mk where it can be shared by other ZDS-II platforms.
* boards/z16/z16f: Duplicate changes for new ZDS-II support from ez80
* boards/z80/z8: Duplicate changes for new ZDS-II support from ez80
* arch/z16/src/z16f/Toolchain.defs: Create required Toolchain.defs file for Z16f
arch/z80/arc/ez80/Toolchain.sh: Move more common toolchain definitions from Make.defs.
boards/z80/ez80/scripts/eZ80_Config.mk: Move common defines that override tools/Config.mk to this new file.
This does not solve the ez80 build problem yet but does assure that when the solution is in place, it will automatically apply to all present and future ez80 configurations.
