Or you may rename CONFIG_TARGET_JETSON_TK1  to CONFIG_BOARD_JETSON_TK1
or another name.

I don't want to force CONFIG_TARGET_  name convention.
You can change config names if you like. It is up to you.


FYI, this is the reason why I used CONFIG_TARGET_  when I
auto-generated the initial version of Kconfig and defconfig files:

The 'integrator' board is supported for various ARM cores such as
arm720t, ar920t, arm926ejs, arm1136.  They use the same board
but different config headers.
So CONFIG_BOARD_INTEGRATOR is not an identical macro pointing to
the config header.

When I see Tegra family, each board has its own config header.
CONFIG_BOARD_ as well as CONFIG_TARGET_ will work.



In future, perhaps only the SoC select
(CONFIG_TEGRA20, _TEGRA30, _TEGRA114, _TEGRA124)
will rename in the Kconfig and
the board select might be pushed into device trees.
I am not sure..
