3) There is a chance that the timer code is actually pretty

and we don't need DM_CLK.
FWIW I'm working on 3) at the moment. So if that works out, we can use
CONFIG_TIMER on kirkwood and then apply your initial patch. As there
are
no bugfix releases for u-boot anyway, we don't have to care for a
backport
fix.
Ah damn, we cannot do this depending on wether CONFIG_TIMER is set or
not.
E.g. on a per-device basis. Or we do some ugly stuff as
#ifdef CONFIG_TIMER
#define CONFIG_SYS_TCLK ((readl(CONFIG_SAR_REG) &
BIT(21)) ? \
166666667 : 200000000)
#else
#define CONFIG_SYS_TCLK 200000000
#endif
So it seems we are back to 1) or 2) :(
