Enable shared stack watchpoint for overflow detection
Enable unit tests:
* "test printf using shared buffer stack" for C3
* "Test vTaskDelayUntil" for S2
* "UART can do poll()" for C3
This adds support for the retargetable locking implementation in
newlib 3. This feature will be enabled in the future toolchain builds.
With the present version of the toolchain, this code doesn't get used.
When _RETARGETABLE_LOCKING gets enabled, newlib locking implementation
will be modified as follows:
- Legacy ESP-specific _lock_xxx functions are preserved. This is done
because ROM copies of newlib in ESP32 and ESP32-S2 rely on these
functions through the function pointer table. Also there is some
code in IDF which still uses these locking functions.
- New __retarget_lock_xxx functions are introduced. Newlib expects
these functions to be provided by the system. These functions work
pretty much the same way as the ESP-specific _lock_xxx functions,
except one major difference: _lock_acquire receives the lock pointer
by value, and as such doesn't support lazy initialization.
- Static locks used by newlib are now explicitly initialized at
startup. Since it is unlikely that these static locks are used at
the same time, all compatible locks are set to point to the same
mutex. This saves a bit of RAM. Note that there are still many locks
not initialized statically, in particular those inside FILE
structures.
* Target components pull in xtensa component directly
* Use CPU HAL where applicable
* Remove unnecessary xtensa headers
* Compilation changes necessary to support non-xtensa gcc types (ie int32_t/uint32_t is no
longer signed/unsigned int).

Spinlocks from spinlock.h do not disable the scheduler and thus cannot safely
be directly used as a locking mechanism. A task holding the lock can get
pre-empted, and at that point the new running task will also be allowed to
take the spinlock and access whatever it was protecting.
Another issue is that the task holding a spinlock could migrate to a different
core which in turn would cause the application to fail asserts. The current
implementation assumes the core that takes the lock is also the core that
releases it.

- Introduce system time function and concept of system time provider.
esp_timer is system time provider when present.
- Set the reference point for system time, g_startup_time.
- Use the system time functions in newlib instead of calling esp_timer
functions directly
esp_common/shared_stack: refactored the implemenation of shared stack function (still not working properly)
esp_expression_with_stack: refactored the shared stack function calling mechanism and updated the documentation
If the olddelta argument is not a null pointer, the adjtime function returns information

BSDs and Unices defined some non standardised functions and symbols used
for endianness handling: converting from Little Endian to Big Endian,
converting from Host to a specific representation, converting from a
specific representation to Host.
With this commit, a modified version of those symbols provided by
FreeBSD is imported.
The license of the imported code is still 2-Clause BSD.

Programs and libraries using compiler and system information about
endianness often include the system header `<endian.h>`.
In `xtensa-gcc` compiler with `newlib` distribution, that file is located in
`<machine/endian.h>`; this means that `#include <endian.h>` would fail
at compile time.
This commit fixes the issue by adding a compatibility `<endian.h>`
header which in turn just includes `<machine/endian.h>`.

esp2020r1 toolchain includes a nano.specs file, which instructs GCC to
substitute libc.a with libc_nano.a.
In the build system, this simplifies handling of the nano formatting
option, eliminating LIBC and LIBM global variables.

newlib/assert: fix assert macro that uses likely
freertos/port: add the missing sdkconfig.h back
newlib/assert: assert macro back to a single line
Since in b0491307, which has introduced the optimized window spill
procedure, _xt_context_save did not work correctly when called from
_xt_syscall_exc. This was because unlike _xt_lowint1, _xt_syscall_exc
does not save PS and EPC1. The new version of _xt_context_save
modified PS (on purpose) and EPC1 (accidentally, due to window
overflow exceptions), which resulted in a crash upon 'rfi' from the
syscall.
This commit adds restoring of PS and EPC1 in _xt_context_save. It also
slightly reduces the number of instructions used to prepare PS for
window spill.
Unit test for setjmp/longjmp (which were broken by this regression)
is added.

1. Since BLE full-scan feature for BLE mesh change the controller code cause this problem,
it cause coex semaphore take in "interrupt disable", then it may cause task schedule

Do not include bootloader in flash target when secure boot is enabled.
Emit signing warning on all cases where signed apps are enabled (secure
boot and signed images)
Follow convention of capital letters for SECURE_BOOT_SIGNING_KEY
variable, since it is
relevant to other components, not just bootloader.
Pass signing key and verification key via config, not requiring
bootloader to know parent app dir.

!4452 used setting LINK_LIBRARIES and INTERFACE_LINK_LIBRARIES to link
components built under ESP-IDF build system. However, LINK_LIBRARIES does
not produce behavior same as linking PRIVATE. This MR uses the new
signature for target_link_libraries directly instead. This also moves
setting dependencies during component registration rather than after all
components have been processed.
The consequence is that internally, components have to use the new
signature form as well. This does not affect linking the components to
external targets, such as with idf_as_lib example. This only affects
linking additional libraries to ESP-IDF libraries outside component processing (after
idf_build_process), which is not even possible for CMake<v3.13 as
target_link_libraries is not valid for targets not created in current
directory. See https://cmake.org/cmake/help/v3.13/policy/CMP0079.html#policy:CMP0079
Using xxx_periph.h in whole IDF instead of xxx_reg.h, xxx_struct.h, xxx_channel.h ... .
Cleaned up header files from unnecessary headers (releated to soc/... headers).
Removes the need to know/guess the paths to these libraries. Once we are gcc 8 only, we
can remove -nostdlib and no additional arguments are needed for system libraries.
The catch is: any time IDF overrides a symbol in the toolchain sysroot, we need
an undefined linker marker to make sure this symbol is seen by linker.
This MR removes the common dependency from every IDF components to the SOC component.
Currently, in the ``idf_functions.cmake`` script, we include the header path of SOC component by default for all components.
But for better code organization (or maybe also benifits to the compiling speed), we may remove the dependency to SOC components for most components except the driver and kernel related components.
In CMAKE, we have two kinds of header visibilities (set by include path visibility):
(Assume component A --(depends on)--> B, B is the current component)
1. public (``COMPONENT_ADD_INCLUDEDIRS``): means this path is visible to other depending components (A) (visible to A and B)
2. private (``COMPONENT_PRIV_INCLUDEDIRS``): means this path is only visible to source files inside the component (visible to B only)
and we have two kinds of depending ways:
(Assume component A --(depends on)--> B --(depends on)--> C, B is the current component)
1. public (```COMPONENT_REQUIRES```): means B can access to public include path of C. All other components rely on you (A) will also be available for the public headers. (visible to A, B)
2. private (``COMPONENT_PRIV_REQUIRES``): means B can access to public include path of C, but don't propagate this relation to other components (A). (visible to B)
1. remove the common requirement in ``idf_functions.cmake``, this makes the SOC components invisible to all other components by default.
2. if a component (for example, DRIVER) really needs the dependency to SOC, add a private dependency to SOC for it.
3. some other components that don't really depends on the SOC may still meet some errors saying "can't find header soc/...", this is because it's depended component (DRIVER) incorrectly include the header of SOC in its public headers. Moving all this kind of #include into source files, or private headers
4. Fix the include requirements for some file which miss sufficient #include directives. (Previously they include some headers by the long long long header include link)
This is a breaking change. Previous code may depends on the long include chain.
You may need to include the following headers for some files after this commit:
- soc/soc.h
- soc/soc_memory_layout.h
- driver/gpio.h
- esp_sleep.h
The major broken include chain includes:
1. esp_system.h no longer includes esp_sleep.h. The latter includes driver/gpio.h and driver/touch_pad.h.
2. ets_sys.h no longer includes soc/soc.h
3. freertos/portmacro.h no longer includes soc/soc_memory_layout.h
some peripheral headers no longer includes their hw related headers, e.g. rom/gpio.h no longer includes soc/gpio_pins.h and soc/gpio_reg.h
BREAKING CHANGE
Fixed adjtime function: While using the adjtime() function,
the time correction accumulated an error
when reading the time frequently (using gettimeofday).
1. separate rom include files and linkscript to esp_rom
2. modefiy "include rom/xxx.h" to "include esp32/rom/xxx.h"
3. Forward compatible
4. update mqtt
This uses a hack (temporarily defining __rtems__ from a wrapper header
file) to include timeradd, timersub, and similar macros, without
modifying newlib headers.
* Prevents section type conflict errors if (say) const & non-const data
is put into the same section (ie with DRAM_ATTR)
* Allows linker --gc-sections to remove unused custom sections
Don’t allow the compiler to convert malloc + memset into calloc,
causing a recursive call in _calloc_r. Fixes crash when building with
-O2 optimization level.
New unity component can be used for testing other applications.
Upstream version of Unity is included as a submodule.
Utilities specific to ESP-IDF unit tests (partitions, leak checking
setup/teardown functions, etc) are kept only in unit-test-app.
Kconfig options are added to allow disabling certain Unity features.
In some cases, linker could choose to use ROM functions instead of the
ones defined in IDF.
For functions used in ROM stub table, this would lead to infinite
recursion when the corresponding function was called from ROM.
For crypto functions, some of these were modified in IDF, and
incompatible with ROM counterparts.
This introduces the following changes :
* Implmentation added for pthread attribute related functions :
* pthread_attr_init
* pthread_attr_destroy
* pthread_attr_setdetachstate
* pthread_attr_getdetachstate
* pthread_attr_getstacksize
* pthread_attr_setstacksize
* pthread_create now supports passing attributes/configs through pthread_attr_t structure
* pthread_mutex_timedlock added
* pthread_exit added
* memory for joinable thread is freed before returning from pthread_join
Before entering the deep sleep, the RTC and FRC counters are synchronized. Updating the boot_time.
Added a unit test for this case.
Fixed warnings for MULTIPLE_STAGES

This function speeds up or slows down the system clock in order to make a gradual adjustment. This ensures
that the calendar time reported by the system clock is always monotonically increasing, which might not happen
if you simply set the clock.
The delta argument specifies a relative adjustment to be made to the clock time. If negative, the system clock is
slowed down for a while until it has lost this much elapsed time. If positive, the system clock is speeded up for a
while.
If the olddelta argument is not a null pointer, the adjtime function returns information about any previous time
adjustment that has not yet completed.
The return value is 0 on success and -1 on failure.
To stop the adjustement, call the function settimeofday(current_time).
* Philosophical: "explicit is better than implicit".
* Practical: Allows useful errors if invalid directories given in components as the defaults aren't
always used. Also trims the -I path from a number of components that have no actual include
directory.
* Simplifies knowing which components will be header-only and which won't
libc time function now rely on esp_timer_get_time as the source of
high-resolution time, rather than FRC1 timer. Internally, on the ESP32
esp_timer implementation uses FRC2 timer.
- Change help text and labels in Kconfig to use "high-resolution timer"
instead of FRC1. Keep existing Kconfig option name to be backwards
compatible.
- Change references to "FRC1" in the source code to "FRC".
These functions were discarded but not provided in ROM.
Generated from commit 8ad0aa7d6 in newlib script repo. Didn't rebuild most of libc/libc_nano,
only appended the missing object files to the existing archives (should save some git churn).
