f327a9b1cf esp32: don’t reset APP CPU if it was already reset by OpenOCD
When ‘reset halt’ command is executed, OpenOCD will take the APP CPU
out of reset and enable the clock. At this point, user can set a
breakpoint on code which will run on APP CPU. Previously, app startup
code would do another reset of APP CPU, thereby removing any breakpoints
which may have been set. This change makes APP CPU reset conditional on
DPORT_APPCPU_CLKGATE_EN bit, which is 0 by default but is set to 1 by
OpenOCD after reset.

2. If access DPORT register, must use DPORT_REG_READ/DPORT_REG_WRITE and DPORT_XXX register operation macro.

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.

f73c6f875c Merge branch 'bugfix/dont_log_before_bss_inited' into 'master'
Remove ESP_EARLY_LOGI before bss is initialized; it crashes the CPU

There's an ESP_EARLY_LOGI line that can get called before the BSS is initialized; the early logging code doesn't cope well with that: it checks if FreeRTOS is up, but the variables it uses for that contains garbage because it isn't cleared yet, giving the wrong result. The logging code then tries to set a mux, crashing the entire system. This patch removes the log line and adds a warning at the BSS initialization line not to do anything complex before that point.

Fixes https://github.com/espressif/esp-idf/issues/523

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.

1. Add disable PHY and RF when WiFi and BT are both disabled(including call sniffer disable API).

2. Do not init PHY and RF when cpu start. Init PHY and RF when call Wifi or BT start APIs(including sniffer enable API).

3. Add a temporary lib: librtc_clk.a and will delete it when CPU frequency switching function is done.

4. Add an function to get OS tick rate.

5. Do not put the whole pp.a in iram0, only put lmac.o, ieee80211_misc.o, ets_time.o and wdev.o in iram0.

777816cb99 phy_init: don’t rewrite valid calibration data
In the default PHY init routine, calibration data is loaded from NVS.
Most of the time the incremental changes to calibration will be fairly
small, so we don’t need to rewrite the existing calibration data stored
in the NVS.

Possible enhancement to be done in the future: expose a function in PHY
library to tell how big was the change in calibration data. If the
change was significant, then calibration data stored in NVS should be
updated.

13d802262a cpu_start: disable boot watchdog only after starting the main task
Boot watchdogs were disabled very early in startup code. It was possible to introduce an infinite loop anywhere in the many functions called from startup code, and this would not be detected by interrupt watchdog and task watchdog. This change postpones disabling of boot watchdogs to the point when the scheduler is running. Also replaces register expressed using integer address with a name.

ffeffcd315 Merge branch 'feature/crosscore_int' into 'master'
Add cross-core int to accelerate task being awoken from another CPU.

This adds a per-CPU interrupt that can be used to poke the CPU to go do something. In this case all that is implemented is a request to yield the current task, used in case a CPU unblocks a task that runs on another CPU. This gets rid of the limitation that inter-CPU communication using queues, muxes etc can take up to a FreeRTOS tick to happen.

Specs!
Sending an in in a queue of length 1 (essentially a semaphore) as quickly as possible (just a small delay in the sender, to make sure the receiver task gets swapped out) for 10 seconds. Number indicates the amount of ints transferred

Old code:

CPU0->CPU0: 42986

CPU0->CPU1,: 2999

New code:

CPU0->CPU0: 42868

CPU0->CPU1: 62073

  Adding -fstrict-volatile-bitfields to the CFLAGS/CXXFLAGS. Without this, gcc tries to access bitfields using the smallest possible methods (eg l8i to grab an 8-bit field from a 32-bit). Our hardware does not like that. This flag tells gcc that if a bitfield is volatile, it should always use the type the field is defined at (uint32_t in our case) to size its access to the field. This fixes accessing the hardware through the xxx_struct.h headers.
