omap3: incorrect logical check in do_emif4_init
((readl(&emif4_base->sdram_iodft_tlgc) & (1<<10)) == 0x01)
is always false.
This does not match the comment
/*Wait till that bit clears*/
The problem was indicated by cppcheck.
I do not have the hardware to test if the code change below
leads to a correct system behavior.
