26a3cb93c7 component/soc : move dport access header files to soc 
1. move dport access header files to soc
2. reduce dport register write protection. Only protect read operation

f7e8856520 component/esp32 : fix dualcore bug 
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.

655fd2986a Add interrupt allocation scheme / interrupt sharing. Also modifies drivers and examples. Also allows interrupts 
to be marked specifically as having a handler that's all in IRAM.

d0801fdbab Merge branch 'feature/sha_tls_integration' into 'master' 
SHA acceleration integrated to mbedTLS incl. TLS sessions

Uses hardware SHA acceleration where available, fails over to software where not available.

79646f41b5 Fixes for stdlib.h inclusion 
Refs:
http://esp32.com/viewtopic.php?f=13&t=550
http://esp32.com/viewtopic.php?f=13&t=551

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.

2561b68af8 hwcrypto: Fixes for disabling one hardware unit causing reset of a different unit 
ROM functions reset related units, but this can have problems in a
multithreaded environment.

1d47755588 mbedtls hardware bignum: Use memcpy instead of REG_WRITE/REG_READ in a loop 
Removes memory barriers for better performance, thanks Ivan for pointing
this out.

Manually unrolling the loop further seemed like diminishing returns.
