d4d4d7324a efuse: Don't need to burn WR_CRYPT_CNT if CRYPT_CNT is already max
Reduces write cycles, and useful on ESP32 ECO3 as UART_DIS_DL is protected by
the same efuse.

Also fixes accidental macro definition introduced in 7635dce502

fc0d6a99f8 secure boot v2: Don't log warnings when BLK2 is empty as expected
If BLK2 is empty then it's OK to continue with a warning (otherwise it may spook users into thinking
something this is wrong, but this is the expected workflow.)

If BLK2 is not empty and doesn't match then we need to fail because it won't be possible to
trust the signature.

25aa5b0e28 esp32: Enable flash encryption by setting FLASH_CRYPT_CNT to max
Previous method was to write-protect this efuse, however on ECO3
the write protect field also covers the UART_DOWNLOAD_DIS efuse.

Doing it this way keeps the possibility of disabling UART download
mode, later.

91841a53ff WDT: Add LL and HAL for watchdog timers
This commit updates the watchdog timers (MWDT and RWDT)
in the following ways:

- Add seprate LL for MWDT and RWDT.
- Add a combined WDT HAL for all Watchdog Timers
- Update int_wdt.c and task_wdt.c to use WDT HAL
- Remove most dependencies on LL or direct register access
  in other components. They will now use the WDT HAL
- Update use of watchdogs (including RTC WDT) in bootloader and
  startup code to use the HAL layer.

409b3db22f bootloader_support: initialize mbedtls_ctr_drbg_context per mbedtls v2.16.5 requirement
In commit 02d2903e39, mbedtls was
updated to release v2.16.5, where it was made mandatory to initialize
mbedtls_ctr_drbg_context before using same. It was fixed in wpa supplicant
but missed out in secure boot v2 verification code. This commit
fixes that.

d40c69375c bootloader: Add fault injection resistance to Secure Boot bootloader verification
Goal is that multiple faults would be required to bypass a boot-time signature check.

- Also strengthens some address range checks for safe app memory addresses
- Change pre-enable logic to also check the bootloader signature before enabling SBV2 on ESP32

Add some additional checks for invalid sections:

- Sections only partially in DRAM or IRAM are invalid
- If a section is in D/IRAM, allow the possibility only some is in D/IRAM
- Only pass sections that are entirely in the same type of RTC memory region

490bf29767 esp32s2: fix enabling 32k XTAL clock
On the ESP32S2, rtc_clk_cal(RTC_CAL_RTC_MUX) measures the frequency
of the 90kHz RTC clock regardless of the selected slow clock
frequency. Keep track which clock is selected and pass the argument
to rtc_clk_cal accordingly.

fix clock choices

fad639f0d4 feature(psram): update psram initialization.
1. use spi functions in rom
2. remove unnecessary GPIO configurations.
3. remove unnecessary dummy settings.
4. enable dummy out function
5. flash and psram have independent timing setting registers.
6. no need to set 1.9v for LDO in 80Mhz
7. set IO driver ability to 1 by default.
8. no need to use GPIO matrix on esp32s2, IO MUX is recommended
9. enable spi clock mode and IO mode settings

* Don't print the "info" level about the revision & min revision unless
  we're in the bootloader (otherwise it gets printed at random times
  during the OTA process)
