037c079e9a esp32: Refactor backtrace and add esp_backtrace_print()
This commit refactors backtracing within the panic handler so that a common
function esp_backtrace_get_next_frame() is used iteratively to traverse a
callstack.

A esp_backtrace_print() function has also be added that allows the printing
of a backtrace at runtime. The esp_backtrace_print() function allows unity to
print the backtrace of failed test cases and jump back to the main test menu
without the need reset the chip. esp_backtrace_print() can also be used as a
debugging function by users.

- esp_stack_ptr_is_sane() moved to soc_memory_layout.h
- removed uncessary includes of "esp_debug_helpers.h"

8e8cb1a139 panic: prevent INT WDT from re-triggering in OCD mode
When INT WDT fires, panicHandler is invoked. In OCD mode, panicHandler
sets a breakpoint on the PC from the exception frame and returns.
However in case of INT WDT, interrupt flag is still set in TIMERG1
peripheral, which causes INT WDT to trigger again. This causes an
endless stream of "Core  0 panic'ed (Interrupt wdt timeout on CPU1)"
messages. OpenOCD also gets terribly confused at this point.

Disable watchdogs when exiting panic handler in OCD mode.
Clear TIMERG1 WDT interrupt flag to prevent re-entry into panic handler.

01b185977c brownout detector: enable by default
Because of errata related to BOD reset function, brownout is handled as follows:

- attach an ISR to brownout interrupt
- when ISR happens, print a message and do a software restart
- esp_restart_nonos enables RTC watchdog, so if restart fails,
  there will be  one more attempt to restart (using the RTC
  watchdog)

8d43859b6a esp32: SEGGER SystemView Tracing Support
Implements support for system level traces compatible with SEGGER
SystemView tool on top of ESP32 application tracing module.
That kind of traces can help to analyse program's behaviour.
SystemView can show timeline of tasks/ISRs execution, context switches,
statistics related to the CPUs' load distribution etc.

Also this commit adds useful feature to ESP32 application tracing module:
 - Trace data buffering is implemented to handle temporary peaks of events load

21f02a6955 Bugfix - Panic Handler not halting when running on both cores
Bug occurs when core dump destination in menuconfig is set to flash. When
programme crashes, xt_unhandled_exception or panicHandler will both trigger
commonErrorHandler. commonErrorHandler calls esp_core_dump_to_flash which
will attempt to use DPORT functions and hang due to trying to a stall and already
stalled processor (already stalled in xt_unhandled_exception and panicHandler).
Program will eventually be rebooted when wdt expires.

Added esp_dport_access_int_deinit after calls to haltOtherCore() so that DPORT
functions don't try to halt and already halted cpu hence preventing hang.

Fixes TW#12944 https://github.com/espressif/esp-idf/issues/646

5d7bffea2b panic handler: Print backtraces with calling address not return address
This seems to clean up some of the more wrong addr2line output results (not
sure why, something to do with optimisations I think - perhaps the return
address may also be a jump target from some earlier line of the code.)

47e789f538 abort handler: Fix abort stack trace when abort() called in ISR
Previously, this resulted in task stack frames turning up incorrectly in the backtrace, ie

Backtrace: 0x400d22a0:0x3ffb0fa0 0x40085a3c:0x3ffb0fc0 0x400f32c4:0x3ffb0fe0 0x40081965:0x3ffb1010
0x400d22a0: esp_vApplicationIdleHook at /home/esp/esp-idf/components/esp32/./freertos_hooks.c:
52
0x40085a3c: prvIdleTask at /home/esp/esp-idf/components/freertos/./tasks.c:4431
0x400f32c4: i2c_isr_handler_default at /home/esp/esp-idf/components/driver/./i2c.c:598
0x40081965: _xt_lowint1 at xtensa_vectors.o:?

Fix is to implement abort() via an unhandled exception rather than a breakpoint, I think
because of relative priority of exception types.

Another approach would be to assign a software-only INUM to abort()ing and defined a
PANIC_RSN_ABORTED, but this is more complex and interrupt numbers are more scarce than RAM!

esp32: Core dump sanity checks

Adds sanity checks when doing core dump to flash

- CRC for core dump flash partition config
- Tasks with corrupted TCBs are skipped
- Assertions to check that nothing is written beyond core dump flash partition

6353bc40d7 Add support for 32k XTAL as RTC_SLOW_CLK source
- RTC_CNTL_SLOWCLK_FREQ define is removed; rtc_clk_slow_freq_get_hz
  function can be used instead to get an approximate RTC_SLOW_CLK
  frequency

- Clock calibration is performed at startup. The value is saved and used
  for timekeeping and when entering deep sleep.

- When using the 32k XTAL, startup code will wait for the oscillator to
  start up. This can be possibly optimized by starting a separate task
  to wait for oscillator startup, and performing clock switch in that
  task.

- Fix a bug that 32k XTAL would be disabled in rtc_clk_init.

- Fix a rounding error in rtc_clk_cal, which caused systematic frequency
  error.

- Fix an overflow bug which caused rtc_clk_cal to timeout early if the
  slow_clk_cycles argument would exceed certain value

- Improve 32k XTAL oscillator startup time by introducing bootstrapping
  code, which uses internal pullup/pulldown resistors on 32K_N/32K_P
  pins to set better initial conditions for the oscillator.

55f1a63faf esp32: Adds functionality for application tracing over JTAG
- Implements application tracing module which allows to send arbitrary
   data to host over JTAG. This feature is useful for analyzing
   program modules behavior, dumping run-time application data etc.
 - Implements printf-like logging functions on top of apptrace module.
   This feature is a kind of semihosted printf functionality with lower
   overhead and impact on system behaviour as compared to standard printf.
