The configuration file at the moment only contains the CMSIS NVIC
virtualization macros. When FEATURE_UVISOR is set, we turn on CMSIS NVIC
virtualization automatically.
This removes the need for users to specify the macros themselves.
If UVISOR_SUPPORTED is set as well, the NVIC macros are turned into vIRQ
ones, otherwise they stay NVIC as usual, thanks to the fallback
implementation provided by `unsupported.h`.
This commit uses the previously introduced feature of generating
configuration data as a C header file rather than as command line macro
definitions. Each toolchain was modified to use prefix headers if
requested, and build_api.py was modified to set up the toolchain's
prefix header content using the data generated by the config system.
Tested by compiling blinky for GCC and ARMCC. I'm having a few issues
with my IAR license currently, but both ARMCC and IAR use the same
`--preinclude` option for prefix headers, so this shouldn't be an issue.
Note that at the moment all exporters still use the previous
configuration data mechanism (individual macro definitions as opposed to
a prefix header). Exporters will be updated in one or more PRs that will
follow.
The current implementation of the configuration system "compiles" the
configuration parameters to macros defined on the command line. This
works, but has a few limitations:
- it can bring back the maximum command line length issues in Windows.
- depending on the type of the configuration parameter, it might require
special quoting of its value in the command line.
- various 3rd party IDE/tools seem to have some limitations regarding
the total length of the macros that can be defined.
This commit is the first step in replacing the current mechanism with
one that generates configuration in header files that will be
automatically included, instead of command line macro definitions. The
commit only adds the method for generating the header file, it doesn't
actually change the way config is used yet (that will happen in step 2),
thus it is backwards compatible. The logic of the configuration system
itself is unchanged (in fact, the whole change (not only this commit) is
supposed to be completely transparent for the users of the configuration
system).
The commit also fixes an issue in tools/get_config.py that appeared as a
result of a recent PR: the signature of "get_config" in
tools/build_api.py changed, but tools/get_config.py was not updated.
Previously it was .zip always, even when using sources. This patch fixes it:`
```
Successful exports:
* K64F::uvision path\projectfiles\uvision\Unnamed_Project_K64F
```
Previously, .hex files were not copied when building source as a library.
This prevents builds that pre compile source as a library and then
includes the build directory as the only source (because there is no
softdevice present). This PR copies hex files when compiling source
as a library.
