Thanks.
In my Virtual Eboot itself i am not passing OEMaddressTable address to
kernelstart. But, jumping and woking fine. really, i couldn't find the
reason, (I'm using Lubbock code)

Even, i tired to pass OEMAddressTable address in r0 register before moving
the KernelEntry address in to my program counter...not getting called.
