In some cases (when RTC register reads are performed from the APP CPU), a write to FRC_TIMER_INT_REG may be lost on the bus.
Writing to another DPORT register immediately before or after that works around the issue.
We write one dummy value to an address which doesn’t have any register associated with it.

One common pattern of using assert function looks as follows:
int ret = do_foo();
assert(ret == 0); // which reads as: “do_foo should never fail here, by design”
The problem with such code is that if ‘assert’ is removed by the preprocessor in release build,
variable ret is no longer used, and the compiler issues a warning about this.
Changing assert definition in the way done here make the variable used, from language syntax perspective.
Semantically, the variable is still unused at run time (as sizeof can be evaluated at compile time), so the compiler
can optimize things away if possible.
These functions are marked as inline and are called from functions which are in IRAM.
In release (-Os) builds, the compiler may decide not to inline these functions.
Placing these functions into IRAM explicitly works around this.

See merge request !420
If using WIFI_INIT_CONFIG_DEFAULT, error message will point out lack
of WiFi. Otherwise linker errors on WiFi symbols should help give a
clue as to what is broken.
Piggy-backs on changes in !420, ref github #230#237
Fix panic register dump format
Fix misplaced a printf somewhere causing an enter to be printed after every register in the panic regdump instead of every 4th register.

4) Core dump module logging facility
5) cache util functions doc updated
6) interactive delay before print core dump to uart
7) core dump partion support in build system
component bt:Added the create attribute table method to the new API
GATT Server service table APIs.
Have already modify the style and other things as @jeroen suggestion in other MR(the MR have been closed)

Deep sleep stub may call ets_update_cpu_frequency, which has been moved from ROM to IRAM.
Restore the ROM version in the linker script, call it ets_update_cpu_frequency_rom, use it in the deep sleep stub.
fix mbedtls unit tests, fix IDF_VER when building a project outside ESP-IDF tree
- mbedTLS test needs about 5% more time to run (in debug mode) when building with 5.2.0, compared to 4.8.5. Increase the timeout to let the test pass.
- when doing `git describe` in IDF_VER definition, `-C $(IDF_PATH)` is needed to get the version of ESP-IDF, and not the project being built (which may not even be in git)

1) PS is fixed up to allow GDB backtrace to work properly
2) MR!341 discussion: in core dump module: esp_panicPutXXX was replaced by ets_printf.
3) MR!341 discussion: core dump flash magic number was changed.
4) MR!341 discussion: SPI flash access API was redesigned to allow flexible critical section management.
5) test app for core dump feature was added
6) fixed base64 file reading issues on Windows platform
7) now raw bin core file is deleted upon core loader failure by epscoredump.py
Complimentary changes:
1) Partition table definitions files with core dump partition
2) Special sub-type for core dump partition
3) Special version of spi_flash_xxx
4) espcoredump.py is script to get core dump from flash and print useful info
5) FreeRTOS API was extended to get tasks snapshots
Clean up WiFi & Bluetooth config options
* Splits "WiFi" configuration out from ESP32 configuration submenu to its own menu.
* Renames "BT" to "Bluetooth", enabling Bluetooth is now in this option not the ESP32 submenu.
* Also disables compiling/linking of BT stack if Bluetooth is disabled, saves some build time.

update toolchain version, rebuild newlib
- This MR updates the toolchain version used in the ESP-IDF
- Compiler version check and warning is added to project.mk
- Newlib is rebuilt to include wcsftime function
- libstdc++ build uses correct newlib headers (so we won't get undefined reference to `__impure_ptr` anymore)

component/bt: bug fix of lack of checking bluetooth stack status inside API functions
Add an API function for checking bluetooth stack status: whether it is uninitialized, initialized or enabled.
The function is intended to be used by users to check the bluetooth stack status, also, it is used inside bluetooth API functions to ensure the stack is in valid state.

Place cross-core interrupt into IRAM, sanity check handler address passed into esp_intr_alloc
Cross-core interrupt handler was not marked with IRAM_ATTR.
The reason why this caused an exception is probably due to some tasks running at highest priority (these are not blocked by spi_flash_disable_caches_interrupts_and_other_cpu mechanism).
This change puts the interrupt handler into IRAM and adds a sanity check into `esp_intr_alloc`.

build system: add IDF_VER environment variable and preprocessor define
This adds an `IDF_VER` preprocessor define which is obtained from `git describe`.
Looks like `v1.0-275-g0efaa4f` for non-release version or `v2.0` for a tagged (release) version.

Add option to automatically set a watchpoint at the end of the swapped-in task
This should make stack overflows easier to debug because it triggers a debug exception as soon as the stack is overwritten, not later when a context switch happens. Marked as a FreeRTOS debug feature because it doesn't give a nice error message and uses up a watchpoint.

Fix tcpip_adapter_set_hostname issue

Fix OpenOCD detection code
In the current master, detection of an attached OCD is broken. This fixes it.
I also snuck in two unrelated checks in intr_alloc which return from a function that is asserted earlier in the code. This makes the code behave better when they are called erroneously in a production build.
