Or simply change the default in Kconfig to something like:

default 20000 if ARCH_K3 || ARCH_OMAP2PLUS || ARCH_KEYSTONE
default 4000

Much better than 45 patches updating each board defconfig individually.

Side question, if this is right for TI plats, why is it not right for
all the other platforms? Should this be the new base default timeout?
I don't really think so in either case, the point of the timeout is to
switch to a fallback port or boot mode in a reasonable time, not sure
20 seconds is reasonable..

(you probably don't need ~50 people in the TO/CC on this one either, not
everyone who has ever touched the defconfigs cares about PHY timeouts)
