* Refactor flash setup for MIMXRT105x devices, adds flash support for MIMXRT1062 EVK
* Remove commented code
* Use BOARD_FLASH_SIZE in boot headers
* Fix setting which should be disabled in run mode
We put macros in a response file compile_time_defs.txt and pass it
to the compiler. Adding a pair of single quotes around each -D flag
ensures macro values are quoted correctly.
For example,
* String
* target_compile_definitions(): either FOO="BAR" or FOO=\"BAR\"
* response file: '-DFOO="BAR"'
* actual definition: #define FOO "BAR"
* Array of integers
* target_compile_definitions(): FOO={1, 2, 3}
* response file: '-DFOO={1, 2, 3}'
* actual definition: #define FOO {1, 2, 3}
CMake versions 3.20 and below always add compiler and linker flags
based on `CMAKE_SYSTEM_PROCESSOR`, for example `--cpu=Cortex-M33`.
This sometimes overrides flags we set in tools/cmake/cores/*.cmake
and results in link failure or unbootable binaries. To workaround
this, we added more linker flags to "counter" what CMake automatically
adds.
From CMake 3.21 onwards, CMake by default does not add flags to
armclang anymore, and it fully relies on projects to set all flags.
In this case we do not need to set `CMAKE_SYSTEM_PROCESSOR` or use
workarounds anymore. We still turn on workarounds when an older
version of CMake (3.19 and 3.20) is used, but in the future we might
require users to have at least CMake 3.21.
To avoid conflicts as we expose our CMake list files via CMAKE_MODULE_PATH. Some files already include it, this
aligns the rest of files.
I leave app.cmake as it is - it's user facing and it would be breaking change. We can clean this one for the next major version.
