- Raise the maximum allowed value in KConfig to 256KB

9d63e1da4a New Task Watchdog API (Revert of Revert)
This commit reverts the revert on the new task watchdog API. It also
fixes the following bug which caused the reversion.

- sdkconfig TASK_WDT_TIMEOUT_S has been reverted from the unit of ms back to the
unit of seconds. Fixes bug where projects using the new API without rebuilding sdkconfig
would cause the old default value of 5 to be interpreted in ms.

This commit also adds the following features to the task watchdog

- Updated idle hook registration to be compatible with dual core hooks

- Updated dual core hooks to support deregistration for cpu

- Legacy mode has been removed and esp_task_wdt_feed() is now replaced by
  esp_task_wdt_reset().  esp_task_wdt_feed() is deprecated

- Idle hooks to reset are now registered/deregistered when the idle tasks are
  added/deleted from the Task Watchdog instead of at Task Watchdog init/deinit

- Updated example

1da3204a7c spiram: expose function to initialize SPI RAM cache
Some frameworks based on ESP-IDF need to be able to decide whether to
initialize SPI RAM after the application has started. This change splits
out part of esp_spiram_init which manipulate cache MMU into a separate
function. Applications can disable cache, call esp_spiram_init_cache,
re-enable cache, and then call esp_spiram_init.
Disabling and re-enabling the cache can be achieved using functions
provided in esp_spi_flash.h.

616baa239d esp32: New Task Watchdog API
Legacy API of task watchdog used the same function esp_task_wdt_feed() to add
and feed a task. This caused issues of implicitly adding a task to the wdt list
if the function was used in shared code.

The new API introduces init, adding, feeding, deleting, deinit functions. Tasks
must now be explicitly added to the task watchdog using their handles. Deletion
must also be explicit using task handles. This resolves the issue of implicit
task additions to the task watchdog due to shared code calling
esp_task_wdt_feed().

Task watchdog is now fully configurable at runtime by calling the init and
deinit functions.

Also added functions to get the handles of idle tasks of the other core. This
helps when adding idle tasks to the watchdog at run time.

Configuring the task watchdog using menu config is still available, however
menu config will only result in calling the init and add functions for idle
tasks shortly after the scheduler starts.

Menu config also allows for using legacy behavior, however the legacy behavior
willcall the new API functions but with slight variations to make them legacy
compatible.

Documentation and example have also been updated

gcov_rtio.c headers updated to prevent error of freertos header files being
included in the wrong order.

2b0f623259 bootloader/early boot: Error out if >192KB of static DRAM is allocated (temporary fix)
Currently the last 128KB of DRAM is reserved for the bootloader & early boot stacks. This means if >192KB of static DRAM
is allocated, the only available heap is this region - which is disabled until the scheduler starts. As a result, you
get either heap corruption on early boot if the static data overlaps startup heap (leading to very weird errors), or
FreeRTOS will fail to start when it can't malloc() anything.

Long term fix is to move the stacks & bootloader data to the very end of RAM, and only reserve that part for early
boot. This is a little fiddly because of also wanting to make sure this memory is not preemptively fragmented when it
gets reintroduced to the heap. This will become more important if/when we have more static allocation options in the
future.

For now, these errors make it clear why the boot has failed.

f327a9b1cf esp32: don’t reset APP CPU if it was already reset by OpenOCD
When ‘reset halt’ command is executed, OpenOCD will take the APP CPU
out of reset and enable the clock. At this point, user can set a
breakpoint on code which will run on APP CPU. Previously, app startup
code would do another reset of APP CPU, thereby removing any breakpoints
which may have been set. This change makes APP CPU reset conditional on
DPORT_APPCPU_CLKGATE_EN bit, which is 0 by default but is set to 1 by
OpenOCD after reset.

6353bc40d7 Add support for 32k XTAL as RTC_SLOW_CLK source
- RTC_CNTL_SLOWCLK_FREQ define is removed; rtc_clk_slow_freq_get_hz
  function can be used instead to get an approximate RTC_SLOW_CLK
  frequency

- Clock calibration is performed at startup. The value is saved and used
  for timekeeping and when entering deep sleep.

- When using the 32k XTAL, startup code will wait for the oscillator to
  start up. This can be possibly optimized by starting a separate task
  to wait for oscillator startup, and performing clock switch in that
  task.

- Fix a bug that 32k XTAL would be disabled in rtc_clk_init.

- Fix a rounding error in rtc_clk_cal, which caused systematic frequency
  error.

- Fix an overflow bug which caused rtc_clk_cal to timeout early if the
  slow_clk_cycles argument would exceed certain value

- Improve 32k XTAL oscillator startup time by introducing bootstrapping
  code, which uses internal pullup/pulldown resistors on 32K_N/32K_P
  pins to set better initial conditions for the oscillator.

f73c6f875c Merge branch 'bugfix/dont_log_before_bss_inited' into 'master'
Remove ESP_EARLY_LOGI before bss is initialized; it crashes the CPU

There's an ESP_EARLY_LOGI line that can get called before the BSS is initialized; the early logging code doesn't cope well with that: it checks if FreeRTOS is up, but the variables it uses for that contains garbage because it isn't cleared yet, giving the wrong result. The logging code then tries to set a mux, crashing the entire system. This patch removes the log line and adds a warning at the BSS initialization line not to do anything complex before that point.

b3f6cd08db support for console redirection to other UART
This change adds a set of menuconfig options to set custom UART#, baud rate, and pins, for console output.
Setting happens in bootloader startup code for PRO CPU, and in application startup code for APP CPU.

ffeffcd315 Merge branch 'feature/crosscore_int' into 'master'
Add cross-core int to accelerate task being awoken from another CPU.

This adds a per-CPU interrupt that can be used to poke the CPU to go do something. In this case all that is implemented is a request to yield the current task, used in case a CPU unblocks a task that runs on another CPU. This gets rid of the limitation that inter-CPU communication using queues, muxes etc can take up to a FreeRTOS tick to happen.

Specs!
Sending an in in a queue of length 1 (essentially a semaphore) as quickly as possible (just a small delay in the sender, to make sure the receiver task gets swapped out) for 10 seconds. Number indicates the amount of ints transferred

Old code:

CPU0->CPU0: 42986

CPU0->CPU1,: 2999

New code:

CPU0->CPU0: 42868

CPU0->CPU1: 62073
