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.

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).
Testing
stm32f4discovery:netnsh
So call 'make EXTRAFLAGS=-Wno-cpp' could suppress the warnings with pre-processor
directive #warning in GCC.

Resolution of Issue 619 will require multiple steps, this part of the first step in that resolution: Every call to nxsem_wait_uninterruptible() must handle the return value from nxsem_wait_uninterruptible properly. This commit is only for those files under fs/driver, fs/aio, fs/nfs, crypto/, and boards/.
Please note: The modified file under fs/nfs generates several " Mixed case identifier found" errors. Please ignore these. These cannot be fixed without changes to numerous other files. They also follow a non-standard convention that is used many files: Using lower case structure names in custom SIZEOF_ definitions.
Update linker scripts to provide _ramfuncs sections for SAMv7 based boards. This corrects undefined reference to _ramfuncs when CONFIG_ARCH_RAMFUNCS is enabled (Issue #304)
Because we can get the same function by CONSOLE_SYSLOG/syslog_console_init.
BTW, it isn't a good choice to use g_ramlogfops as /dev/console since nsh
will read back what it send out which will surprise most people.
This commit adds automounter and BOARDCTRL_RESET support for SAMV71 and verified on Atmel SAMV71-XULT. Also, some fixes of Kconfig and missing uerr/uinfo definition.
