I was over-zealous in arch/z80/src/ez80/ez80f91_handlers.asm. I added space separatros around the '+' operators. Turns out that the ZDS-II assembler can't handle the spaces in that context.
The ez80f92 is similar to the currently supported ez80f91 except that is:
1. Has no PLL and has a maximum CPU frequency of only 20MHz
2. Has no Ethernet controller
3. Timers are different
4. Has no GPIO Port A
5. Timers are different
6. It comes in a smaller package
and other small differences.
This provided the architecture (only) support for the forthcoming z20x port.
* arch/arm/src/tiva/Make.defs: Compile only when enabled by configuration CONFIG_ARM_SEMIHOSTING_HOSTFS
* arch/arm/src/common/up_hostfs.c: Remove the ifdef conditional because it's redundant with the make logic.
Largely copy-and-paste from stm32f4discovery.
Also arch/arm/src/armv7-m/mpu.h: Ensure RBAR alignment
Fix crashes on init task startup I observed on qemu-system-arm -M lm3s6965evb.
And remove syslog_init_e because all initialization is later now and we don't
distinguish the initialition phase anymore after ramlog don't need special
initialize.
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.
it doesn't make sense that iob initialization is in up_initialize
but other memory components initialization is called in nx_start

To ensure size_t same as toolchain definition in the first place and rename CXX_NEWLONG to ARCH_SIZET_LONG. The change also check whether __SIZE_TYPE__ exist before CONFIG_ARCH_SIZET_LONG so our definition can align with toolchain(gcc/clang) definition automatically.
Currently up_allocate_heap() assumes that g_idle_topstack points
top of the heap memory. However, g_idle_topstack pointed incorrect
address in SMP mode which resulted in heap corruption. This PR
moves g_idle_topstack at the end of .noinit to avoid this issue.

The benefit include:
1. Simplify the implementation
2. Support both tick and tickless automatically
3. No time drift in tickless mode
4. Support critmon arch API automatically
To avoid ps generate "Segmentation fault" because do_stackcheck
check the stack color if the stack size doesn't equal zero
BTW, it is better to set idle task stack size to zero since idle
task use the host thread and the stack size from config isn't the
actual value.
The benefits include:
1. Simplify the implementation
2. Support Ctrl+C automatically
3. Support poll automatically
4. Call pm_activity automatically
5. Save one polling thread
Call xxx_timer_initialize from clock subsystem to make timer ready for use as soon as possiblei and revert the workaround:
commit 0863e771a9

Revert "sched/clock/clock_initialize.c: clock_inittime() needs to be done with CONFIG_SCHED_TICKLESS and clock_initialize should skip clock_inittime() for external RTC case since the RTC isn't ready yet."
This reverts commit 2bc709d4b9.
Commit 2bc709d4b9 was intended to handle the case where up_timer_gettime may not start from zero case. However, this change has the side-effect of breaking every implementation of tickless mode: After this change the tickless timer structures are used before they are initialized in clock_inittime(). Initialization happens later when up_initialize is called() when arm_timer_initialize().
Since the tickless mode timer is very special, one solution might be to
1. Rename xxx_timer_initialize to up_timer_initialize
2 Move up_timer_initialize to include/nuttx/arch.h
3. Call it from clock subsystem instead up_initialize
Basically, this change make timer initialization almost same as rtc initialization(up_rtc_initialize).
For now, however, we just need to revert the change.
* include: Introduce elf64.h and elf.h
Added elf64.h for 64bit ELF support and moved common definitions
from elf32.h to elf.h. Also introduced Elf_xxx to be used in
common libraries such as binfmt.
* binfmt, include, modlib, module: Add support for ELF64
Elf_xxx must be used instead of Elf32_xxx to support ELF64.
To use ELF64, CONFIG_ELF_64BIT must be enabled.
* binfmt, modlib: Add support for relocate address
* arch: risc-v: Add include/elf.h
* libs: machine: Add risc-v related files.
NOTE: Currently only supports ELF64
* boards: maix-bit: Add elf and posix_spawn configurations
* boards: maix-bit: Add support for module configuration
* S32K add support for Nxp drone boards
* Update arch/arm/src/s32k1xx/hardware/s32k1xx_rtc.h codestyle

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.
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.
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.
