of all tasks at runtime.

[Omar Chebib: Prevent task switching while printing backtraces of tasks.]
[Omar Chebib: Ensure all task stacks are flushed from register to RAM.]
[Omar Chebib: Removed esp_task_snapshot_to_backtrace_frame() as task snapshot is private API.]
[Omar Chebib: Added test case for esp_backtrace_print_all_tasks().]

On riscv chips accessing cache mapped memory regions over the ibus would
result in an illegal instructions exception triggering faster than the cache
error interrupt/exception.
Added a cache error check in the panic handler, if any cache errors are active
the panic handler will now report a cache error, even if the trigger exception
was a illegal instructions.
Many places in the ESP_SYSTEM are using CONFIG_FREERTOS_UNICORE instead of CONFIG_ESP_SYSTEM_SINGLE_CORE_MODE (GitHub PR)

This commit deprecates the "freertos/xtensa_context.h" and "xtensa/xtensa_context.h"
include paths. Users should use "xtensa_context.h" instead.
- Replace legacy include paths
- Removed some unnecessary includes of "xtensa_api.h"
- Add warning to compatibility header

CONFIG_ESP_TIMER_ISR_AFFINITY can be equal to -1, whereas
ESP_SYSTEM_INIT_FN takes an uint16_t argument. To avoid overflow,
move the choice of init mask into source code and set the value
explicitly.
Similar to how the secondary init functions were already registered
via ESP_SYSTEM_INIT_FN, do the same for the core init functions.
This MR doesn't actually move the init functions into respective
components yet. This has to be carefully done in follow-up MRs.
Common spi functionality for sharing the SPI bus between modules is moved from esp_driver_spi to
a more fitting location in esp_hw_support (shared HW resource control).
This also allows us to decouple the spi_flash driver from esp_driver_spi, removing
esp_driver_spi and esp_ringbuf from G1 builds.
In ESP32-H2, the ECDSA peripheral by default uses the TRNG (hardware)
generated k value but it can be overridden to software supplied k.
This can happen through by overriding the `ECDSA_SOFTWARE_SET_K` bit
in the configuration register. Even though the HAL API is not exposed
for this but still it could be achieved by direct register
programming. And for this scenario, if sufficiently random k is not
supplied by the software then it could posses a security risk.
In this change, we are unconditionally programming the efuse
`ESP_EFUSE_ECDSA_FORCE_USE_HARDWARE_K` bit during startup security
checks itself. Additionally, same is ensured in the `esp_efuse_write_key`
API as well. This always enforces the hardware k mode in the ECDSA
peripheral and ensures strongest possible security.
esp-system and esp-hw-support, and the rest of the g1 components, now only depend on
esp_driver_spi and esp_driver_gpio. Removing the rest of the driver components from g1 builds.
This commit deprecates xTaskGetAffinity(), xTaskGetCurrentTaskHandleForCPU()
and xTaskGetIdleTaskHandleForCPU() APIs for IDF-FreeRTOS kernel.
Instead, users are directed to use alternatives. All other
components in IDF using these functions have been updated accordingly.
1st bootloader won't help to initialize the MSPI & cache properly as it
usually do when loading from flash. And the ram app doesn't have valid
headers.
Since there is no enough space in 2nd bootloader, we replace the
`bootloader_init_spi_flash` in the ram_app (!pure_ram_app), with an
customized alternative of it for the ram_app.
This alternative helps to initialize the MSPI & cache properly, without
the help of 1st bootloader or image headers.
This commit mainly targets the ESP32-P4. It adds supports for coprocessors on
RISC-V based targets. The coprocessor save area, describing the used coprocessors
is stored at the end of the stack of each task (highest address) whereas each
coprocessor save area is allocated at the beginning of the task (lowest address).
The context of each coprocessor is saved lazily, by the task that want to use it.
Task snapshot API were never intended to be called from user code. This commit
makes task snapshot a private API thus moves `#include "freertos/task_snapshot.h"`
to `#include "esp_private/freertos_debug.h"`.
Task snapshot related Kconfig options have also been hidden.
Note: Added 'freertos_common' mapping to ldgen mapping execptions lists due to
inlining of 'freertos_debug.h' functions.
For cases where the bootloader is not enabled with the security features
ends up receiving an incorrect application with flash encryption enabled
should not really program any security efuses.
In the startup sequence, we first used to program the ROM DL mode
configuration but now we check for the flash encryption related checks
first. If the flash encryption related checks finds that flash
encryption is not enabled on the device then it aborts the boot process.
This is the case with `CONFIG_SECURE_FLASH_CHECK_ENC_EN_IN_APP` enabled.
This would at-least ensure that accidental program of security enabled
application does not really program any ROM DL mode efuses and there is
chance to recover the device.
Previously, Task Snapshot could be conditionally built based on the
CONFIG_FREERTOS_ENABLE_TASK_SNAPSHOT option. However, there is no overhead
with always enabling Task Snapshot functions, as the linker will remove any
functions if they are not called.
This commit...
- removes all ESP-IDF dependencies on the CONFIG_FREERTOS_ENABLE_TASK_SNAPSHOT
option so that Task Snapshot functions are always available.
- Makes CONFIG_FREERTOS_ENABLE_TASK_SNAPSHOT a hidden option to maintain
compatibility with user code.
- adds documentation regarding Task Snapshot.
