- Replace all users of `$(RIOTBASE)/build` with the already present
`$(BUILD_DIR)` variable
- Replace all users of `$(BUILD_DIR)/pkg` with the already present
`$(PKGDIRBASE)` variable
- Create a `CACHEDIR.TAG` file in the `$(BUILD_DIR)`
The ram size is exposed as macro value and available for use in code.
For the stm32 it has a value in kilobytes suffixed with 'k'. This is
less than optimal for usage in arithmetic. This commit modifies the
value to bytes so that it can be used in preprocessor magic
Normally, CMSIS headers are retrieved as package from ST git repository
for each stm32.
However stm32mp1 family does not have a CMSIS headers repository but
have been included into RIOT source code in a previous commit.
For stm32mp1, CMSIS headers package must then not be retrieved and
vectors have to be generated from already in-source CMSIS headers.
