Introduced in 9c23b8e5 and 4f87a62f. To get higher speed, menuconfig
options are added to put ISR and other functions into the IRAM. The
interrupt flag ESP_INTR_FLAG_IRAM is also mistakenly set when the ISR is
put into the IRAM. However callbacks, which are wrote by the user, are
called in the master and slave ISR. The user may not be aware of that
these callbacks are not disabled during flash operations. Any cache miss
during flash operation will cause panic.
Essentially IRAM functions and intrrupt flag ESP_INTR_FLAG_IRAM are
different, the latter means not disabling the ISR during flash
operations. New bus_config flag intr_flags is offered to help set the
interrupt attribute, including priority level, SHARED, IRAM (not
disabled during flash operations). It introduced a small BREAK to
IDFv3.1 (but the same as IDFv3.0) that the user has to manually set IRAM
flag now (therefore he's aware of the IRAM thing) to void the ISR being
disabled during flash operations.
1. Fix interrupt watchdog timeout in bluetooth "btdm_bb_isr"
2. Fix BLE assert(512) or assert(1536) in rwble.c at line 222
3. Update librtc.a to fix BLE assert(512) in rwble.c at line 222
The #1 and #2 occurs random.
The #3 bug occurs in certain scenario:
1. If Wifi start softap and BLE is working
2. If wifi start station, but do not use normal station operation, such
as just use espnow, while BLE is working
3. Any other scenario, that wifi works without use software coexist
operation, while BLE is working(such as do advertising and ...)
4. update libcoexist.a version to v1.1.2
This commit resolves a blocking in esp_aes_block function.
Introduce:
The problem was in the fact that AES is switched off at the moment when he should give out the processed data. But because of the disabled, the operation can not be completed successfully, there is an infinite hang. The reason for this behavior is that the registers for controlling the inclusion of AES, SHA, MPI have shared registers and they were not protected from sharing.
Fix some related issue with shared using of AES SHA RSA accelerators.

Having two different spinlocks is problematic due to possibly
different order in which the locks will be taken. Changing the order
would require significant restructuring of kernel code which is
undesirable.
An additional place where taking xTickCountMutex was needed was in
vApplicationSleep function. Not taking xTickCountMutex resulted in
other CPU sometimes possibly advancing tick count while light sleep
entry/exit was happening. Taking xTickCountMutex in addition to
xTaskQueueMutex has shown a problem that in different code paths,
these two spinlocks could be taken in different order, leading to
(unlikely, but possible) deadlocks.
1. Fix the bug that disable controller suddenly cause crash when ble is working
2. Fix the bug that when disable controller, it will cause wifi cannot RX, TX timeout, buffer lack and etc.
1. When WIFI task or other high priority task blocks the Bluetooth task, ACL RX buffer will use up, ACL RX buffer ptr will point to null and will never point to a valid adress. Causing errors in Bluetooth.
2. hcimsgs.h used whether flow control is on or off
1. resolve the error in calculating sniff anchor point that result in connection supervision timeout
2. resolve the issue of user case that requires sniff attempt is larger than 0xff
It is possible to utilize some of the routines related to otadata
partition validation, after firmware image is downloaded to RAM. Hence
these routines should be part of app cpu cache, so that they do not
get overwritten by firmware.

Fix following WiFi bugs:
1. Fix the bug that MIC verification fails on soft-AP mode
2. Modify mesh root to have same behavior as normal WiFi STA in state change
3. Fix the bug that sniffer can't catch control packets
4. Fix crash bug in soft-AP mode
5. Fix ACM(Admission Control Management) bug
1. fix some bugs by previous coex hw blocking bugfix,
such like, rwble.c (64, 0) line 222
2. fix bug that ble scan performance is very low when software coexist
is working.
3. update libcoexist version to v1.1.0
1. remove use EID to distinguish psram voltage
2. 1V8 64Mbit psram and 3V3 64Mbit psram use the same psram driver(standard spi interface)
3. set cs hold time register as 1
1. Add reading psram EID.
2. Configure different clock mode for different EID.
3. add API to get psram size and voltage.
4. Remove unnecessary VSPI claim.
For 32MBit@1.8V and 64MBit@3.3V psram, there should be 2 extra clock cycles after CS get high level.
For 64MBit@1.8 psram, we can just use standard SPI protocol to drive the psram. We also need to increase the HOLD time for CS in this case.
EID for psram:
32MBit 1.8v: 0x20
64MBit 1.8v: 0x26
64MBit 3.3v: 0x46
1. Fix the bug that ESP32 will reject the retry AddBA request frame
if AddBA response frame is failed to sent by WiFi LMAC
2. Fix the bug that AddBA request retrys too frequently
3. Forbid BA session setup for VO queue related TID
Routine `spi_flash_cache2phys` sometimes return incorrect value,
resulting in failure in getting currently running ota partition.
This in turn aborts firmware update process.This issue was more
prominent with SPIRAM enabled cases.
Fix ensures proper cache guards during `spi_flash_cache2phys`, and
also for few other similar APIs.
In addition, `esp_ota_get_running_partition` has also been optimized
to save currently running partition for subsequent invocations.
Fixes https://github.com/espressif/esp-idf/issues/2451
Problem Description
The reporduce steps are as follows:
1.This issue can be reproduced with 4 ESP32 devices, 2 for stations (STA1, STA2) and 2 for soft-AP (AP1, AP2)
2.Configure AP1/AP2 to the same SSID (ssid_xxx)
3.The max allowed WiFi connections of AP1 is configured to 1 and STA1 connects to AP1
4.The AP1 is close to STA2 while AP2 is far away from STA2 (but the STA2 can find the AP2 via scan)
5.STA2 connects ssid_xxx with all scan method
6.The problem will happen on STA2 because it fails to connec AP1 and never connects AP2
Phenmenon
STA fail to connect after send auth or assoc with a wrong status code, but no disconnect event report and can not connect the next one in the envrionment
Root Cause
Because there are some same ssid APs in the evnrionment, when do all channel scan, it will collect all the matched AP in rc list, because rc list is not empty, so it would send disconnect event, however, we didn't do other step such as connect to other one

fix the bug following:
1. after disable bluetooth controller, wifi cannot TX/RX any packets.
2. when software coexist working, there's a little ratio cause wifi task
watchdog timeout
3. when software coexist working, there's a little ratio cause bluetooth
cannot receive anything.
feature:
1. add libbtdm_app.a git commit local and remote checking
Known issues:
1. there's still a bug occurs with a very very low ratio cause bluetooth
cannot receive anything. The reproduce interval may great than 3days
~ 1week via 7x24 hours heavy testing.
1. suppport mesh type, mesh ID, router and IE crypt func&key at any time after mesh is initalized.
2. support modify parent at any time after mesh is configured.
3. modify manual networking example.
4. update header file.
5. fix issues in root conflicts handling.
6. add max length of beacon to menuconfig.
7. fix issue when received a beacon without DSSS.
This change removes the earlier limitation of 1984 bytes for storing data-blobs.
Blobs larger than the sector size are split and stored on multiple sectors.
For this purpose, two new datatypes (multi-page index and multi-page data) are
added for entries stored in the sectors. The underlying read, write, erase and find
operations are modified to support these large blobs. The change is transparent
to users of the library and no special APIs need to be used to store these large
blobs.
Backport following WiFi fixes to v3.1:
1. Fix AMPDU RX sequence compitability bug
2. Optimize scan capability in all channel scan
3. Fix some modem sleep bugs
4. Update API to set CSI channel filter and HT_LTF data generating
Allocation was happening later, causing possible use of stack variables
of caller function, which could be invalid.

AVRCP connection binds to A2DP in current implementation, despite the two profiles are\
independent according to specification. AVRCP connection is not necessary to set-up \
if A2DP connection fails to establish
In opening state of AVDTP connection, if SDP client fails to get valid A2DP service record\
from peer SDP server, then do not initiate AVDTP connection request
In pevious implementation, A2DP sink will register an A2DP source Stream End Point(SEP) although the SEP is not\
supposed to be used. Now remove the unused SEP for source so that only one role of A2DP can be supported at one
time. Service record in local SDP server only includes at most one service for A2DP sink role or source

Before fixing, the tx power in adv data is always 0xeb(-21dbm).
restriction:
If change BLE advertising TX power, please call esp_ble_gap_config_adv_data()
after BLE adv TX power changed.
Later, will implement set BLE advertising TX power via HCI, then the
TX power value in adv data can be update automatically after BLE adv
TX power changed.
Currently CI test environment is complicated, usually includes NIC, AP.
These devices are not used for a lot test cases. Therefore we split the
test environment, remove unnecessary devices. Then it will be easier to
create CI runners.
As the bluedroid original implmentation of BR/EDR and BLE dual mode about discovery mode,
when set discovery mode for BR/EDR, it will stop ble advertising.

The following commit rewrites the ESP-MESH docs. This commit includes
new diagrams and a structure approach to the mesh docs. Some mesh api references
have also been modified.
Some APs transmit AMPDU and MPDU by turns. Moreover, the sequence
numbers of AMPDU and MPDU are out of order, e.g. MPDU(1253) -
AMPDU(1251, 1252) - MPDU(1254) - AMPDU(1255, 1256). In order to
receive both AMPDU and MPDU in order, MPDU must be reordered with
AMPDU.
1. new APIs: esp_mesh_get_subnet_nodes_num() and esp_mesh_get_subnet_nodes_list().
2. fix hard to find the parent during connect.
3. disable Wi-Fi channel switch function.
4. fix a typo of MESH_EVENT_NO_PARENT_FOUND.
Multiple modules register their callback BTA_GATTS_AppRegister().
If any of the callbacks do not free the allocated pointer in
BTA_GATTS_CONF_EVT event, then this can result in memory leak.
So, free the pointer after the callback function is called and remove
the calls to free in the callback functions as it is now not required

4. Fix the bug that WiFi assert the system when receiving empty MCS in association response frame
We have fixed a bug in test script. Before that, we didn't do strict check when generate the mesh tree, which makes the test pass.
Temp disable these cases, to let CI pass before bug fixed.
For pins 32 and up the BIT(nr) macro used here overflowed,
causing undetermined GPIO pins to be reset.
Example: freeing SPI device/bus where CS is on pin 33
caused debug UART to cease communication, TXD0 was
disabled.
Fixed as BIT64(nr) macro, to be used elsewhere as needed.
For example in definitions like GPIO_SEL_32..GPIO_SEL_39.
