In commit de22f3a4e5, combination of
hardware and software MPI (bignum) related approach was used to
work around chip (e.g. ESP32-C3) limitation of max 3072 bits support.
This was done using linker "--wrap" flag but since the relevant API is
being used in same translation (compilation unit), hardware mode was not
getting used in some cases (e.g., RSA key generation).
This commit modified internal mbedTLS API and makes software+hardware
combination deterministic.
Add configuration option to fallback to software implementation
for exponential mod incase of hardware is not supporting it
for larger MPI value.
Usecase:
ESP32C3 only supports till RSA3072 in hardware. This config option
will help to support 4k certificates for WPA enterprise connection.
Using xxx_periph.h in whole IDF instead of xxx_reg.h, xxx_struct.h, xxx_channel.h ... .
Cleaned up header files from unnecessary headers (releated to soc/... headers).
1. separate rom include files and linkscript to esp_rom
2. modefiy "include rom/xxx.h" to "include esp32/rom/xxx.h"
3. Forward compatible
4. update mqtt
This commit resolves a blocking in esp_aes_block function.
Introduce:
The problem was in the fact that AES is switched off at the moment when he should give out the processed data. But because of the disabled, the operation can not be completed successfully, there is an infinite hang. The reason for this behavior is that the registers for controlling the inclusion of AES, SHA, MPI have shared registers and they were not protected from sharing.
Fix some related issue with shared using of AES SHA RSA accelerators.

Avoids growing the result of hardware bignum operations
(particularly for multiplication)
Fixes bugs where some Elliptic Curve operations fail or corrupt memory,
as they assume length of the number is never greater than the number of
non-zero limbs.
Includes some general refactoring to standardize terminology.
Closes https://github.com/espressif/esp-idf/issues/1556
Fixes TW12984
Adds test cases for both these issues.
When two CPUs read the area of the DPORT and the area of the APB, the result is corrupted for the CPU that read the APB area.
And another CPU has valid data.
The method of eliminating this error.
Before reading the registers of the DPORT, make a preliminary reading of the APB register.
In this case, the joint access of the two CPUs to the registers of the APB and the DPORT is successful.
1. When dual core cpu run access DPORT register, must do protection.
2. If access DPORT register, must use DPORT_REG_READ/DPORT_REG_WRITE and DPORT_XXX register operation macro.
SHA acceleration integrated to mbedTLS incl. TLS sessions
Uses hardware SHA acceleration where available, fails over to software where not available.

rmt.c should include stdlib.h for malloc, esp_bignum,c &
https_request_main.c for abort().
FreeRTOSConfig.h is only including stdlib if
CONFIG_FREERTOS_ASSERT_ON_UNTESTED_FUNCTION is set. However, it is
included for abort() so needs to be included whenever
CONFIG_FREERTOS_ASSERT_FAIL_ABORT is set.
This change includes unconditionally in FreeRTOSConfig.h. This is to
avoid this kind of bug where compiler errors are dependent on config. I
suggest we don't change this to be more selective until we have 'make
randomconfig' style tests in CI.
Removes memory barriers for better performance, thanks Ivan for pointing
this out.
Manually unrolling the loop further seemed like diminishing returns.
