*
* Description:
* Configures DDR2 (MT47H128M16RT 128MB or, optionally, MT47H64M16HR)
*
* Per the SAMA5D4-EK User guide: "Two SDRAM/DDR2 used as main system memory.
* MT47H128M16 - 2 Gb - 16 Meg x 16 x 8 banks, the board provides up to 2 Gb on-
* board, soldered DDR2 SDRAM. The memory bus is 32 bits wide and operates with
* up to 166 MHz."
*
* From the Atmel Code Example:
* MT47H64M16HR : 8 Meg x 16 x 8 banks
* Refresh count: 8K
* Row address: A[12:0] (8K)
* Column address A[9:0] (1K)
* Bank address BA[2:0] a(24,25) (8)
*
* This logic was taken from Atmel sample code for the SAMA5D4-EK.
*
* Input Parameters:
* devtype - Either DDRAM_MT47H128M16RT or DDRAM_MT47H64M16HR
*
* Assumptions:
* The DDR memory regions is configured as strongly ordered memory. When we
* complete initialization of SDRAM and it is ready for use, we will make DRAM
* into normal memory.
