The mini u-boot is getting exception because of an initial
stack pointer address is used at near the top of memory,
and while executing u-boot is assigned pre-malloc and
global_data memory after initial stack pointer and updated
the stack pointer. Serial driver is used pre-malloc area
for serial operations before relocation. But pre-malloc area
is cleared while doing BSS at relocation time. The u-boot is
called board_init() function and doing printf, relocation serial
driver is not initialized yet, so it is using before relocation
serial operations but it is cleared by BSS and got the exception.
To fix, change an initial stack pointer address from near the
top of memory to near the relocation memory.
