Since commit 94250e4, EXT0 wakeup mechanism, when wakeup level was set
to 0, started waking up chip immediately after entering deep sleep.
This failure was triggered in that commit by a change of
RTC_CNTL_MIN_SLP_VAL (i.e. minimum time in sleep mode until wakeup
can happen) from 128 cycles to 2 cycles.
The reason for this behaviour is related to the way input enable (IE)
signal going into an RTC pad is obtained:
PAD_IE = (SLP_SEL) ? SLP_IE & CHIP_SLEEP : IE,
where SLP_IE, SLP_SEL, and IE are bits of an RTC_IO register related
to the given pad. CHIP_SLEEP is the signal indicating that chip has
entered sleep mode.
The code in prepare_ext{0,1}_wakeup did not enable IE, but did enable
SLP_SEL and SLP_IE. This meant that until CHIP_SLEEP went high, PAD_IE
was 0, hence the input from the pad read 0 even if external signal
was 1. CHIP_SLEEP went high on the 2nd cycle of sleep. So when
RTC_CNTL_MIN_SLP_VAL was set to 2, the input signal from the pad was
latched as 0 at the moment when CHIP_SLEEP went high, causing EXT0
wakeup with level 0 to trigger.
This commit changes the way PAD_IE is enabled: SLP_SEL and SLP_IE are
no longer used, and IE is set to 1. If EXT0 wakeup is used, RTC_IO is
not powered down, so IE signal stays 1 both before CHIP_SLEEP goes
high and after. If EXT1 wakeup is used, RTC_IO may be powered down.
However prepare_ext1_wakeup enables Hold on the pad, locking states
of all the control signals, including IE.

Previously the loop in esp_timer_impl_set_alarm was necessary to catch
the case when timer count wraps around (goes from 2^32 - 1 to 0).
Since ALARM_OVERFLOW_VAL was reduced from 2^32 - 1 to 0xefffffff,
this is no longer necessary.
Fixes https://github.com/espressif/esp-idf/issues/1891
Allows you to move the partition table, it gives more space for the bootloader.
Added a new utility - parttool.py. This utility can search for the offset and/or size of the partitions by name and type/subtype. Use for getting APP_OFFSET and PHY_DATA_OFFSET.
The linker(esp32.bootloader.ld) made changes that allow you to write a custom bootloader code more.

A new method of workaround an error with DPORT is to ensure that the APB is read and followed by the DPORT register without interruptions and pauses. This fix places this implementation in the IRAM to exclude errors associated with the cache miss.
Add error handling for http client
set ssid password correct with Example_WIFI test, and clear password before free
Fixed the CI failure due to HTTP errror names

2. provide two options for bluetooth low power clock: main XTAL and external 32kHz XTAL
3. provide function and callbacks to control bluetooth low power mode, including enable/disable sleep, software wakeup request, low power clock settings, check power state, etc
4. modify vhci API vhci_host_send_packet to use blocking mode

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.

1. remove rc when ap not found
closes issue: https://github.com/espressif/esp-idf/issues/1797
2. allocate mimo packet to internal memory
3. use FRC2 timer instead of WDEV_NOW() for modem sleep to calculate
TBTT time.
It fixes the bug that TBTT will be incorrect if beacon is lost.
If the RTC crystal is bad or has no matched capacitance, then you do not need to start such the crystal. It is necessary to determine this case, output an error (about impossibility to start from the oscillator) and start from the internal RC of the chain.
Reduced the default value of the number of bootstrap cycles. Because we can oscillating the oscillator which then stops. (in Kconfig). Changed from 100 to 5.
The number of calibration cycles has been increased. It is the main criterion for estimating the launch of an oscillator. A large increase leads to an increase in the load time, as well as the stability of recognition of this case. (in Kconfig).
Changed from 1024 to 3000.
When two CPUs read the area of the DPORT and the area of the APB, the result is corrupted for the CPU that read the APB area.
And another CPU has valid data.
The method of eliminating this error.
Before reading the registers of the DPORT, make a preliminary reading of the APB register.
In this case, the joint access of the two CPUs to the registers of the APB and the DPORT is successful.
If the allocated interrupt list is not empty and the new item will be inserted
as the header of the list, insert_vector_desc() causes crash because pre is
null. This commit fix this issue.
change some API function to throw event:
esp_wifi_deauth_sta
esp_wifi_get_country
esp_wifi_ap_get_sta_list
esp_wifi_sta_get_ap_info
esp_wifi_stop
esp_wifi_get_channel
esp_wifi_get_protocol
esp_wifi_get_bandwidth
When light sleep is started, the other CPU gets halted using DPORT
stall mechanism. This can happen while it is inside an esp_timer
critical section, which may lead to a deadlock. This change adds
functions to take and release esp_timer lock before entering
DPORT critical section, preventing the deadlock.
1. Add error log if failed to store calibration version/mac/data
2. Change the NVS calibration version/mac/data store sequence
3. Pass the init_data instead of NULL to esp_phy_rf_init() in esp_phy_load_cal_and_init()
* 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
1. Bootloader reads SPI configuration from bin header, so that the burning configuration can be different with compiling configuration.
2. Psram mode init will overwrite original flash speed mode, so that users can change psram and flash speed after OTA. 3. Flash read mode(QIO/DIO…) will not be changed in app bin. It is decided by bootloader, OTA can not change this mode.
4. Add read flash ID function, and save flash ID in g_rom_flashchip
5. Set drive ability for all related GPIOs
6. Check raise VDDSDIO voltage in 80Mhz mode
7. Add check flash ID and update settings in bootloader
8. Read flash ID once and keep in global variable
9. Read flash image header once and reuse the result
Tested cases:
1. Test new and old version of bootloader
boot Flash 20M —> app Flash 80M + Psram 80M
boot Flash 40M —> app Flash 80M + Psram 80M
boot Flash 80M —> app Flash 80M + Psram 80M

this as whole component
