1. Remove the unused and unimplemented ipv6_chksum declaration
2. Update NET_ARCH_CHKSUM description to align with the implementation
3. Declare all checksum function prototype regardless CONFIG_NET_ARCH_CHKSUM
4. Remove the CONFIG_NET_ARCH_CHKSUM guard for tcp_ipv[4|6]_chksum

sim: Prefix symbols with _ for non-ELF
Namely for Mach-O. Leave __CYGWIN__ case as it is.
* Serial Fixed interrupt storm
The target would randomly hang in the serial isr.
The priv->ie and the hardware were inconsistent.
The isr used the priv->ie to gate offloading
the RX data. Bang! Hung.
imxrt_disableuartint(priv, &ie);
ret = imxrt_setup(dev);
/* Restore the interrupt state */
imxrt_restoreuartint(priv, ie);
interrupt-> Of no return
priv->ie = ie;
On a fast cpu with FIFO, this will not work
with out proper protections.
* Serial: Conditionally enable 9 bit mode
* armv7-mi/mpu.hi: Restructure API
Preserve the existing API and enabled better granualriy on
setting.
* Enable MPU for non protected builds to set cache
* mpuinit use symbolic values for addresses
* Allow DTCM on HEAP
* allocateheap Fix Coding style
* ld doesn't have --start-groupi/--end-group things. As far as I know,
it works that way by default.
* objcopy with Mach-O support is not widely available.
(GNU binutils seem to claim the support but it didn't actually work
for me. llvm-objcopy --redefine-syms explicitly rejects Mach-O.)
Instead, use -unexported_symbols_list linker flag to hide symbols
to avoid conflicts with host symbols.
It seems that "ld -r" on macOS doesn't include objects from
libraries for common symbols. Because of that, sim build
ends up with undefined references to globals like g_binfmts
and g_mmheap.

configured to support archs: armv6 armv7 armv7s arm64 arm64e arm64_32 i386 x86_64 x86_64h armv6m armv7k armv7m armv7em
LTO support using: LLVM version 11.0.0, (clang-1100.0.33.17) (static support for 23, runtime is 23)
TAPI support using: Apple TAPI version 11.0.0 (tapi-1100.0.11)
The recent x86-64 convention requires 16-byte alignment before
(not after) calling a function.
This fixes snprintf crash I observed on macOS while saving XMM registers.
Namely this changes HOSTOS for macOS from "Other" to "Darwin".
Also, suppress the following harmless messages during a "make":
(Missing redirect in tools/Makefile.host)
uname: illegal option -- o
usage: uname [-amnprsv]
Consider junk.c for example:
/****************************************************************************
* xx
****************************************************************************/
/****************************************************************************
* Private Types
****************************************************************************/
struct foo_s
{
int bar;
};
/****************************************************************************
* Public Functions
****************************************************************************/
int dofoo(int barin)
{
barout = barin;
return barout;
}
nxstyle not detects these problems:

All STM32L4 MPUs have FLASH_CR_PNB bits (8 bits), and some MPUs have FLASH_CR_BKER bit to change bank if page >= 256.
The code wasn't setting or clearing FLASH_CR_BKER correctly.

STM32L4: Add workaround of data cache corruption on RWW.
Some STM32L4 chips has eratta "Data cache might be corrupted during Flash Read While Write operation". This is also in STM32, and arch/arm/src/stm32/stm32f20xxf40xx_flash.c has workaround.
To enable this workaround, define CONFIG_STM32L4_FLASH_WORKAROUND_DATA_CACHE_CORRUPTION_ON_RWW.
Recent changes removed CONFIG_TIME_ENHANCED and unmasked some warnings. These warnings were caused by nuttx/time.h not being included by files that now referenced clock_daysbeforemonth() and clock_isleapyear().
This commit adds those missing inclusions and eliminates the warnings.

Add CONFIG_MMCSD_SDIO=y to configuration. This eliminates the following error found in build testing: lpc17_40_bringup.c: undefined reference to mmcsd_initialize
This capability was erroneously removed by a previous commit. This setting is necessary when the C++ code generated by the compiler uses the new and delete operators provided in libs/libxx.
Here is an example of an error scenario where this capability is required:
1. CONFIG_CXX_NEWLONG=y in the defconfig file
2. This causes libs/libxx to to generate a delete operator of this form:
void delete(void*, unsigned long);
3. But the compiler expects to link with a delete operator of this form:
void delete(void*, unsigned int);
That results in a link-time failure and the ONLY solution for avoiding that link time failure (short of some complete redesign) is to have a control over the CONFIG_CXX_NEWLONG setting and make sture that it is always disabled for that toolchain.
Other toolchains will require that CONFIG_CXX_NEWLONG=y in all cases. This cannot be predicted because it is dependndent on the definitions provided by C libraries and header files that were build into binary toolchain.
