You are right, 832x doesn't have FP, but it also doesn't support ECC memory,
So it doesn't need memory init.
The memory init code is only used with 8349 v1.1 and 8360 v1.1,
The future version of 8349 and 8360 don't need these code, because
Its DDR controller supports memory init function.
Do you have any good idea about memory init?
