Originally marked "Reset with ESP32R0 Windows workaround", but proven to be
necessary on some other platforms as well. This is now integrated into the
default esptool.py reset behaviour.
Closes#305https://github.com/espressif/esp-idf/issues/305
* New "espefuse.py set_flash_voltage" command to easily set a fix
VDD_SDIO regulator voltage (1.8V, 3.3V or disabled).
* Fixes bugs when flashing files with non-4-byte aligned lengths
(doesn't effect esp-idf image files)
* README improvements
Allow separate ethernet & wifi configuration
If only 1/2 of ethernet & WiFi are enabled in config, the other interface is no longer linked into the firmware.
* Fixes bug where enabling Ethernet but not WiFi would fail to compile.
* Also means that enabling WiFi but not Ethernet no longer links some unused ethernet interface functions.

FreeRTOS: Fix cross-core event group sync
As above
Also includes fixes which allowed removing some semi-hacky bits from the event group unit tests - specifically, higher priority tasks will always be started immediately even if they run on the opposite core.
See merge request !535
FATFS enable support for multiple drives
Current implementation has drive numbers and paths hardcoded to support
only one FATFS drive. Arduino has it's own SPI driver to allow
compatibility and flexibility. With the MR it is possible to have up to
```_VOLUMES``` drives connected (SPI, SDMMC and others) at the same
time and accessed through VFS
See merge request !478
freertos kconfig: Add max task length name, move task stack overflow watchpoint
* Allow setting task name length via kconfig
* Move task stack overflow watchpoint out of internals debugging submenu, place next to other stack overflow checks.
* Thread local pointer feature should depend on Ethernet or WiFi
See merge request !531
Partition/SPI/OTA docs & OTA new functionality
* Update partition, SPI flash & OTA docs to reflect functionality changes
* Refactor OTA implementation to perform checks mentioned in API doc
* Add new functions to OTA API: esp_ota_get_running_partition() & esp_ota_get_next_update_partition() functions
* Add spi_flash_cache2phys() & spi_flash_phys2cache() functions to support esp_ota_get_running_partition()

2. Add the number of MAC address generated from efuse for user to choose.
3. Add MAC address derive method.

esp32: Fix hardware rng after esp_wifi_stop (second implementation)
Ensures hardware RNG remains enabled at all times.
Reworked version of !534

lwip: modify dhcp timer granularity from 60s to 1s
Current DHCP granularity is 60 seconds, it's not accurate, it can cause DHCP release/rebind/renew timer
timeout at the same time, also it may renew/rebind/release at wrong time, thus cause problem.
1. RTC V214: modify APLL function for the chip of ECO version.
2. Add API phy_close_rf() and use it in esp_phy_deinit() instead of pm_close_rf().
3. RTC V213: fix BT will not work when BT-init is called more than once.
vfs_fat_sdmmc: if card init fails, fail cleanly
This fixes the issue with sdmmc_host not returned to clean state after a failed attempt to mount the card, with no SD card in the slot.

component/bt : add adv/scan start complete event
1. indicate adv/scan start complete success or failed
2. controller do limit of adv/scan concurrence, so add some codes to report adv/scan start failed or not.
See merge request !524
component/bt:fixed the write ccc crash bug error
fix the gatt server write ccc lead to the system crash if not initialize the ccc value.
See merge request !515
Optimize or release memory in bluetooth
1. add option to release about 30K from BT if BLE only
2. later BT/BLE will be separated by BT/BLE macro, but this option should use when user make sure that in BLE only mode.
See merge request !520
1. indicate adv/scan start complete success or failed
2. controller do limit of adv/scan concurrence, so add some codes to report adv/scan start failed or not.
Fix a scheduling bug
Fixes:
- Trivial bug where in some special cases a task could be started on the wrong core (and would run there for max 1 tick)
- More major bug causing a yield to be done with a mux held.

Fix SPI master transmit length
Tx/Rx length fix from https://github.com/espressif/esp-idf/pull/336
I also added an extra commit in to make use of a define instead of a literal, plus fix a (harmless) off-by-one condition.
See merge request !521
This fixes incorrect descriptions of I_END/I_SLEEP instructions and
changes the definition of I_END. New instruction, I_WAKE, is added,
which wakes up the SoC. Macro for ADC instruction is defined, and new
tests are added.
This change adds esp_deep_sleep_get_wakeup_cause, which returns the
source which has caused wakeup from deep sleep.
Similar to esp_deep_sleep_get_ext1_wakeup_status, a function is added
to check touch pad wakeup status: esp_deep_sleep_get_touchpad_wakeup_status.
This function returns the touch pad which has caused wakeup.
ULP and touch FSMs in ESP32 revisions 0 and 1 do not operate correctly
if RTC_PERIPH power domain is force powered on (ESP_PD_OPTION_ON).
Both ULP and touch still work, but clock frequency of the ULP may be
incorrect and touch values may be off by considerable amount. As such,
when these wakeup modes are used, RTC_PERIPH power domain has to be set
to ESP_PD_OPTION_AUTO (or, in the current implementation,
ESP_PD_OPTION_OFF — though this will change in the future when _OFF will
actually *force* the power domain to be powered off).
Because EXT0 wakeup source requires RTC_PERIPH to be powered ON, mark
ULP and touch wakeup sources as incompatible with EXT0. Workaround for
this is to use EXT1 wakeup source instead, which offers similar or
better functions without having to keep RTC_PERIPH powered on.
- I_RD_REG used the wrong union member (.rd_reg) due to a copy-paste
mistake
- Peripheral register address in bits[7:0] should be given in words,
not in bytes

Deep sleep fixes
This change fixes extra 24 uA current consumption in deep sleep mode (https://esp32.com/viewtopic.php?f=2&t=1133).
Recent update to libphy/librtc caused another problem that WiFi related parts of RTC are no longer disabled by RTC sleep functions. This means that if WiFi is not disabled by the application before entering deep sleep, extra ~200uA of current would be consumed. This is fixed, and documentation for esp_deep_sleep and SNTP example are updated to mention that applications should take care of disabling WiFi and BT before going into the deep sleep mode.

spi_flash: fix protection issues
This MR fixes the two spi_flash related issues:
- esp_intr_noniram_{disable,enable} not being protected by spi_flash_op_{lock,unlock} in single core mode. This caused a safety assert to be triggered in esp_intr_noniram_disable.
- spi_flash_unlock not being protected by spi_flash_guard_{start,end}. This caused a conflict between SPI0 and SPI1 controllers when accessing SPI flash, manifesting in cache data corruption and IllegalInstruction exceptions, for some flash chips.
See merge request !522
spi_flash_unlock was missing spi_flash_guard_start, which caused cache
to be enabled during unlock operation, causing hard-to-trace crashes
and cache data corruption.
MR !441 (7c155ab) has fixed issue with esp_intr_noniram_{disable,enable}
calls not being properly protected by spi_flash_op_{lock,unlock}.
Unit test was added, but the unit test environment tests only dual-core
config. Similar issue was present in the code path for the single-core
config, where esp_intr_noniram_{disable,enable} calls were unprotected.
This change fixes the protection issue and updates the unit test to
run properly in single core config as well.
The issue with running unit tests for single core config will be
addressed in a separate MR.
In case WiFi/BT stack has been enabled but wasn’t disabled, some RTC
bits may be left enabled, causing increased current consumption.
This change returns some of the bits back to their default values.
Bootloader enables SAR ADC in test mode to get some entropy for the RNG.
The bits which control the ADC test mux were not disabled, which caused
extra ~24uA current to be drawn from VRTC, increasing deep sleep current
consumption. This change disables relevant test mode bits in
bootloader_random_disable.
