499d087c91 C++: add provisions for optional RTTI support
Ref. https://github.com/espressif/esp-idf/issues/1684

This change allows RTTI to be enabled in menuconfig. For full RTTI
support, libstdc++.a in the toolchain should be built without
-fno-rtti, as it is done now.

Generally if libstdc++.a is built with RTTI, applications which do not
use RTTI (and build with -fno-rtti) could still include typeinfo
structures referenced from STL classes’ vtables. This change works
around this, by moving all typeinfo structures from libstdc++.a into
a non-loadable section, placed into a non-existent memory region
starting at address 0. This can be done because when the application
is compiled with -fno-rtti, typeinfo structures are not used at run
time. This way, typeinfo structures do not contribute to the
application binary size.

If the application is build with RTTI support, typeinfo structures are
linked into the application .rodata section as usual.

Note that this commit does not actually enable RTTI support.
The respective Kconfig option is hidden, and will be made visible when
the toolchain is updated.

43393cf4d1 bootloader: Support for skipping validation upon wake from deep sleep
This saves time when waking up from deep sleep, but potentially decreases
the security of the system.  If the application able to modify itself
(especially areas that are loaded into RAM) in flash while running
without crashing or is modifies the cached bits of information about
what was last booted from the bootloader, this could cause security
issues if the user does a "deep sleep reset" since the full validation
is skipped.

a79c5b8271 esp32: Rename esp32.common.ld to esp32.project.ld to avoid build errors when downgrading
Linker script generator produces build/esp32/esp32.common.ld from
components/esp32/ld/esp32.common.ld.in

This works fine until IDF is downgraded to V3.1 which uses components/esp32/ld/esp32.common.ld and
doesn't track build/esp32/esp32.common.ld at all.

At this point, the linker runs in the build/esp32 directory and "-T esp32.common.ld" picks up the
linker script generated .ld file, which causes mis-builds.

As reported on forums: https://esp32.com/viewtopic.php?f=13&t=9684&p=40105

ec5eb1e5c2 esp32: Add option to place.rtc_data and .rtc_rodata into the RTC_FAST segment
Changes:
KConfig: The option CONFIG_ESP32_RTCDATA_IN_FAST_MEM is added in Kconfig file for esp32 component.
esp32.common.ld: added support of RTC_DATA_ATTR, RTC_RODATA_ATTR data placement into appropriate segment according to Kconfig option.
esp32.ld: linker script is modified to set alias for memory segment selected by Kconfig option to place data. The segments for force placement are added for RTC_FAST_ATTR, RTC_SLOW_ATTR attributes.
esp_attr.h: added new attributes RTC_FAST_ATTR, RTC_SLOW_ATTR for force placement into fest/slow memory.
test_rtc_fast.c: Added unit test cases to check data placement into appropriate memory segment.
Updated documentation for RTC_DATA_ATTR, RTC_FAST_ATTR, RTC_SLOW_ATTR in deep_sleep_stub.rst file.

f8580ea98f esp32: Change 192KB runtime static limit workaround to a 176KB link time workaround
Turns out some app memory around 0x3ffdc000 is also used by APP CPU.

This is a workaround until code to remove the 176KB limit is committed.

We reserve 4KB Slow RTC memory to save RF calibation result and BT NVS data.
If not all these Slow RTC momory Blocks are used, we will open the other parts.

7c494055e3 esp32: Bootloader wake deep sleep stub
App can contain a stub program resident in RTC fast memory. Bootloader
will load the stub on initial boot. If the device wakes from deep sleep,
the stub is run immediately (before any other data is loaded, etc.)

To implement a custom wake stub, implement a function in your program:

```
void RTC_IRAM_ATTR esp_wake_deep_sleep(void)
{
  esp_default_wake_deep_sleep();
  // other wake logic
}
```

... and it will replace the default implementation.
