49130c6b34 esp_ringbuf: fix default placement from flash to IRAM
In earlier change this component was decoupled from freertos and hence
regression was introduced which changed default placement to flash. Some
device drivers make use of ringbuffer while flash cache is being disabled
and hence default placement should instead be internal memory.

ec5eb1e5c2 esp32: Add option to place.rtc_data and .rtc_rodata into the RTC_FAST segment
Changes:
KConfig: The option CONFIG_ESP32_RTCDATA_IN_FAST_MEM is added in Kconfig file for esp32 component.
esp32.common.ld: added support of RTC_DATA_ATTR, RTC_RODATA_ATTR data placement into appropriate segment according to Kconfig option.
esp32.ld: linker script is modified to set alias for memory segment selected by Kconfig option to place data. The segments for force placement are added for RTC_FAST_ATTR, RTC_SLOW_ATTR attributes.
esp_attr.h: added new attributes RTC_FAST_ATTR, RTC_SLOW_ATTR for force placement into fest/slow memory.
test_rtc_fast.c: Added unit test cases to check data placement into appropriate memory segment.
Updated documentation for RTC_DATA_ATTR, RTC_FAST_ATTR, RTC_SLOW_ATTR in deep_sleep_stub.rst file.

a5ae5ac4b3 soc: Allow components to reserve fixed memory ranges that they need
No longer necessary to keep all reserved addresses in 'soc'.

Means 'soc' does not need to know about 'bt', for example.

Also means that Bluetooth can be enabled in config without any memory being reserved for BT
controller. Only if code calling the BT controller is linked in, will this memory be reserved...

f610249bdd Reclaim BT/BTDM BSS and Data in bluetooth memory release function
1. Modify esp_bt_controller_mem_release() to release BTDM BSS and Data to heap if
ESP_BT_MODE_BTDM mode is passed to it
2. Add a new API esp_bt_mem_release() which internally calls
esp_bt_controller_mem_release() with the provided mode and then if mode
is ESP_BT_MODE_BTDM, releases BT BSS and Data to heap.

Background:
For Wi-Fi and BT/BLE applications, for e.g. the usecase is like when
Bluetooth is used for provisioning and once the device is connected to the Wi-Fi
AP, we can turn off Bluetooth completely. In such scenarios, it should be possible to
reclaim all the memory of Bluetooth. Although, currently this does not
happen.

Experiment:
Made the following modifications to examples/bluetooth/gatt_server :
1. Added support of simple_wifi to it
2. Moved all the bluetooth related code under CONFIG_BT_ENABLED config
option
3. Calculated the free heap in 2 similar scenarios:
   i. Disabled BT (CONFIG_BT_ENABLED undefined) and checked the free
heap after STA connected
   ii. Kept BT enabled and disabled it after STA connected and checked
the free heap
Ideally, the numbers for i., ii. above should have been similar. But
there was a delta of almost 30-31K. (i. > ii.)
4. Through make size-components checked the common BSS for libbta.a and libbtdm_app.a
and found it to be almost 30K. Data is around 1K

Solution:
1. Modified the linker script to mark the BSS and Data for these libraries and
free it when ESP_BT_MODE_BTDM mode is passed to mem release APIs.
2. Verified that the free heap is comparable for i. and ii. above.

Note: It is known that once this is done, Bluetooth can only be used
again post reboot.

44b1bc0ab9 esp32: Add .noinit and .rtc_noinit sections to the linker script
Added .rtc_noinit and .noinit section definitions into linker file /esp32/ld/esp32.common.ld.
The macro __NOINIT_ATTR, RTC_NOINIT_ATTR declared in esp32/esp_attr.h file.
Added unit test file to test added behavior for noinit variables and its attributes.
Added documentation changes for new added attributes.
Make some corrections after code review:
The linker file has been corrected to place noinit section before bss_start to make it safer.
Documentation file has been modified to clarify reset behavior of allocated data .
Corrected typos in test_noinit.c and removed assertion of noinit variable to avoid possible issues with ROM boot loader memory allocation.

73e8afc5b9 soc: place constant data from rtc_clk.c into DRAM
In release mode, switches in rtc_clk_bbpll_set would be converted to
jump tables. These tables would be placed into .rodata, which caused
rtc_clk_cpu_freq_set to be unusable while cache is disabled. This
manifested itself in crashes when exiting from light sleep:

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

9d8425bd72 put RODATA of libphy.a into DRAM
There are some RODATAs of libphy.a that are called in ISR. So need
    to put them into DRAM to avoid access them when R/W SPI flash. Due
    to the RODATAs which are called in ISR haven't been picked out to
    put into DRAM, put all of the RODATA of libphy.a into DRAM. This
    will be optimized in the future.

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.

9edab21385 Merge branch 'feature/rtc_clk_impl' into 'master'
Introduce soc component, add source of rtc_clk and rtc_pm libraries

This MR adds parts of the RTC library source code (initialization, clock selection functions, sleep functions). WiFi-related power management functions are kept inside the precompiled library. Most of RTC library APIs have been renamed.

Default CPU frequency option in Kconfig is set to 160MHz, pending qualification of 240MHz mode at high temperatures.

Register header files are moved into the new soc component, which will contain chip-specific header files and low-level non-RTOS-aware APIs (such as rtc_ APIs). Some of the files from ESP32 component were also moved: cpu_util.c, brownout.c, and the corresponding header files. Further refactoring of ESP32 component into more meaningful layers (chip-specific low level functions; chip-specific RTOS aware functions; framework-specific RTOS-related functions) will be done in future MRs.

710c853adc Merge branch 'bugfix/spi_flash_lock_period' into 'master'
SPI flash operations lock for shorter periods

Based on bug report here:
https://esp32.com/viewtopic.php?f=13&t=1489&p=6816#p6773

Long SPI flash erase (and possibly write/read) cycles block all tasks on both CPUs for an extended period, and can lead to WiFi dissassociation (and general priority inversion.)

This MR inserts preemption breaks into large operations (all erases, writes every 8KB, reads every 16KB).

Overhead of a single spi_flash_guart_start()/spi_flash_guard_end() cycle measured at approx 67us (assuming no preemption.)
