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.
Previously, V=0 would print some verbose lines but not most of them.
This meant that it was impossible to disable all verbose output
when BATCH_BUILD=1

* Fix the situation where component_project_vars.mk is generated before config exists
* Does not fix situation where config is changed and component_project_vars.mk contents should be
changed. This may still require a rebuild.
1. When one of the COMPONENT_DIRS points to a component directory
(i.e. a directory containing component.mk, not a directory of multiple
components), and there is a subdirectory in it which also contains
a component, the subdirectory was mistakenly added to the list of
components and compiled.
For example:
main/
component.mk
main.c
test/
component.mk
test_main.c
Would compile test_main.c and link libtest.a.
2. When one of the COMPONENT_DIRS points to a component directory, and
the parent directory contained a directory with the same name as
another component, that directory would be mistakenly added to the
COMPONENT_PATHS.
For example:
esp/
esp-idf/
esp32/
(random stuff)
mycomponent/
component.mk
mycomponent.c
myproject/
main/
Makefile
and Makefile sets EXTRA_COMPONENT_DIRS=$(realpath ../mycomponent),
then "esp32" directory which is at the same level as mycomponent
was added to COMPONENT_PATHS.
3. If EXTRA_COMPONENT_DIRS pointed to a directory with a list of
components, and one of the subdirectories was not a component, but
had the same name as another component, than that directory would be
mistakenly added to COMPONENT_PATHS instead of the real esp32
component directory.
For example:
my_components/
my_component/
component.mk
my_component.c
esp32/
(some random stuff)
and EXTRA_COMPONENT_DIRS would point to my_components/, then "esp32"
directory would be added to COMPONENT_PATHS instead of the real esp32
component directory.
Added a new structure esp_app_desc_t. It has info about firmware:
version, secure_version, project_name, time/date build and IDF version.
Added the ability to add a custom structure with a description of the firmware.
The esp_app_desc_t is located in fixed place in start of ROM secotor. It is located after structures esp_image_header_t and esp_image_segment_header_t.
app_version is filed from PROJECT_VER variable (if set in custom make file) or PROJECT_PATH/version.txt or git repo (git describe).
Add API to get app_desc from partition.
