It will be better to use CONFIG_${SPL_TPL}WDT in watchdog Makefile,
because all the SoC needs treat this driver separate in TPL/SPL/U-Boot
proper.
Enabling TPL (via DM or so) cannot be an optimal solutions as of now,
I'm not suggesting enable WDT in TPL, but only about how the WDT module
is enabled in Makefile system;
If useing CONFIG_${SPL_TPL}WDT in Makefile, then the WDT is not enabled
in TPL if there is no
CONFIG_TPL_WDT, so you don't have to write the 'undef ...' code for
CONFIG_TPL_BUILD.
Thanks,

since if it continuously resetting we need to take boot switch based
on bootcount, ie possible with SPL and U-Boot proper now. Making a
boot switch to TPL might increase code size, so will check this
decision later based on the requirement.
