1. when one task do deinit/init/disable/enable, especially different cpu
core, it may cause controller crash in ISR handler
2. fix while BLE is scanning, bluetooth controller is disabled cause BLE
scan is not abort.
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.

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.
* Fixes some "noreturn" functions in bootloader utils which did return (causing fatal CPU
exceptions).
* Marks bootloader entry as "noreturn", preventing "user code done" from stalling boot
Partial fix for https://github.com/espressif/esp-idf/issues/1814 TW20016
(Comprehensive fix for this issue will be enabling WDT during bootloader, coming shortly.)
1. Move channel to the first row of the table.
2. Remove the condition of HT20/HT40 for they are determined by
secondary channel.
3. Clean up the CSI table.
Because address space is mapped in 64KB pages, it was possible for unauthenticated data after the
app .bin to become mapped into the flash cache address space.
This problem is solved by 2 changes:
* "esptool elf2image --secure-pad" will pad the image so that the signature block ends close to the
64KB boundary. Due to alignment constraints it will be 12 bytes too short after signing (but
with flash encryption, these 12 bytes are still encrypted as part of the last block and can't be
arbitrarily changed).
* By default, secure boot now requires all app partitions to be a multiple of 64KB in size.
Perviously host send_auto_stop flag would be set for every data
transfer over 1 block long. This caused stop commands to be sent
after CMD53, which shouldn't be done. Fix by adding an explicit list
of commands for which send_auto_stop should be set.
Send the Goodbye packet while removing an mDNS service as an "Authoritative" packet so
that the listeners remove the service from their records immediately.
Fixed the error division on zero.
Also fixed range CONFIG_ESP32_RTC_CLK_CAL_CYCLES in Kconfig.
Fixed a overflow error by TIMG in the function rtc_clk_cal_internal. This error was due to a limit in values TIMG_RTC_CALI_MAX=0x7FFF (to write the slowclk_cycles) and TIMG_RTC_CALI_VALUE=0x1FFFFFF (to read xtal_cycles). Added assert finctions.

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
When 2nd stage bootloader loads the ROM bootloader, it prints a
message similar to "entry 0x40080xxx", which idf_monitor decodes
(using application ELF file) as one of the reset vectors (xxx is <
400h). This moves the iram_seg of bootloader 1k up to prevent overlap
of bootloader .text and application vectors, making the output look
nicer. There is still a chance that the entry point decodes as some
symbol in application ELF file, but at least it won't have
"Exception" in its name.
Since 94250e42a0, UART output is suspended when entering sleep mode
(deep or light sleep). This makes sense for light sleep, where sleep
normally takes small amount of time, and flushing the UART would add
a lot of latency. But this breaks existing behaviour for deep sleep,
where UART output was previously sent out before entering sleep mode.

Fixes https://github.com/espressif/esp-idf/issues/2127
The fix is for the situation when cache disabling mechanism causes
a deadlock with user tasks. Situation is as follows:
1. spi_flash operation is started from low-priority task on CPU0
2. It uses IPC to wake up high-priority IPC1 task on CPU1, preventing
all other tasks on CPU1 from running. This is needed to safely
disable the cache.
3. While the task which started spi_flash operation is waiting for IPC1
task to acknowledge that CPU1 is not using cache anymore, it is
preempted by a higher priority application task ("app0").
4. Task app0 busy-waits for some operation on CPU1 to complete. But
since application tasks are blocked out by IPC1 task, this never
happens. Since app0 is busy-waiting, the task doing spi flash
operation never runs.
The more or less logical soltion to the problem would be to also do
cache disabling on CPU0 and the SPI flash operation itself from IPC0
task. However IPC0 task stack would need to be increased to allow doing
SPI flash operation (and IPC1 stack as well). This would waste some
memory. An alternative approach adopted in this fix is to call FreeRTOS
functions to temporary increase the priority of SPI flash operation task
to the same level as the IPC task.

5. Due to the hardware coexist bug, BLE scan interval/window should
be less than 0x100(about 160ms). Therefore, it will cause BLE cannot

by just marking FATFS parition as encrypted.

Cherry-picked from https://github.com/espressif/esp-idf/pull/1923/
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.

For some test configurations, not all tests need to be run. This
change allows adding a comment in the configuration file of the
following form:
unit-test-app makefile will use it to determine which components to
build. If the comment is not present, all components will be built
(TESTS_ALL=1).
Also add test configuration for libsodium. It is a separate test
configuration due to the large binary size generated when building
libsodium tests.
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.
