At present most of the tests scan the U-Boot source tree as part of their run. This information does not change across tests, so we can save time by remembering it. Add a way to set up this information and use it for each test, taking a copy first, so as not to mess up the original. This reduces the run time from about 1.6 seconds to 1.5 seconds on my machine. For code coverage (which cannot run in parallel), it reduces from 33 seconds to 5. Signed-off-by: Simon Glass <sjg@chromium.org>

"""Device tree to C tool
|
|
|
|
This tool converts a device tree binary file (.dtb) into two C files. The
|
|
indent is to allow a C program to access data from the device tree without
|
|
having to link against libfdt. By putting the data from the device tree into
|
|
C structures, normal C code can be used. This helps to reduce the size of the
|
|
compiled program.
|
|
|
|
Dtoc produces several output files - see OUTPUT_FILES in dtb_platdata.py
|
|
|
|
This tool is used in U-Boot to provide device tree data to SPL without
|
|
increasing the code size of SPL. This supports the CONFIG_SPL_OF_PLATDATA
|
|
options. For more information about the use of this options and tool please
|
|
see doc/driver-model/of-plat.rst
