1. Set the image load partition to the first FAT partition. 2. Set the kernel rootfs partition to the second partition.

This patch adds the i.MX6DL arm2 board support. The i.MX6DL ARM2 shared the same board with i.MX6Q ARM2 board since the i.MX6DL is pin-pin compatible with i.MX6Q.
The patch also support the DDR 32-BIT mode option. Please define CONFIG_DDR_32BIT in the board configure file to enable DDR 32-BIT mode.But due to the board design, it's 64bit DDR buswidth physically, so, if you CONFIG_DDR_32BIT, the DDR memory size will be half of it.

Checking the pre_periph_clk_sel and pre_periph2_clk of CCM CBCMR register, if the PLL2 PFD0 or PLL2 PFD2 is used for the clock source, do not reset this PFD to avoid system hang. Customers may set this in DDR script or use BT_FREQ to select low freq boot.
Signed-off-by: Ye.Li B37916@freescale.com --- Changes since v1: - Add this patch before support LPDDR2 ARM2 board, because LPDDR2 use 400Mhz - DDR and set pre_periph_clk_sel to PLL2 PFD2. So we can't reset PFD2.

Update the ddr scripts for LPDDR2 and add two build configs for LPDDR2 arm2 board. Since the LPDDR2 arm2 board has different DDR size, use CONFIG_DDR_MB in defconfig to replace the PHYS_SDRAM_SIZE.
