In u-boot-1.1.4/board/omap*/lowlevel_init.S,
REG_MPU_LOAD_TIMER is set to address 0xfffec600,
but reading from spru742.pdf, http://focus.ti.com/lit/ug/spru742/spru742.pdf
the correct value seems 0xfffec504 (+0x4 offset from REG_MPU_CNTL_TIMER).
Linux omap patch (http://www.muru.com/linux/omap/) also refer to load reg as fffec504...
This is a patch to change address from fffec600 to fffec504.
