The test 4 = "AddressBus [size] [addr]" without parameter detects alias for any address bit only when: - size = real size of DDR - addr = start of DDR = 0xC0000000
These value must be the default value when parameters are absent.
This patch sets bufsize to STM32_DDR_SIZE and get_bufsize() selects the correct value for bufsize when this parameter is absent = full size of the DDDR
On EV1 board : DDR> test 4 running at 0xC0000000 length 0x40000000
On DK2 board DDR> test 4 running at 0xC0000000 length 0x20000000
