          Use the IA-PC HPET (High Precision Event Timer) to manage
          time in preference to the PIT and RTC, if a HPET is
          present.  The HPET provides a stable time base on SMP
          systems, unlike the TSC, but it is more expensive to access,
          as it is off-chip.  You can find the HPET spec at
          <http://www.intel.com/hardwaredesign/hpetspec.htm>.

config HPET_EMULATE_RTC
        bool "Provide RTC interrupt"
        depends on HPET_TIMER && RTC=y

in pld we have:

CONFIG_HPET_TIMER=y
CONFIG_HPET_EMULATE_RTC=y
CONFIG_HPET=y
CONFIG_HPET_MMAP=y
CONFIG_RTC=y
