  67 ==================
  68 1.1 SW1: 0 - Boot from Socket Flash (AMD) or 1 - Onboard Flash (INTEL)
  69     SW2: 0 - Select MPC8220 UART or 1 - Debug Card UART
  70     SW3: unsed

  75 2. MEMORY MAP UNDER U-BOOT AND LINUX KERNEL
  76 ===========================================
  77 2.1. For the initial bringup, we adopted a consistent memory scheme between u-boot and
  78      linux kernel, you can customize it based on your system requirements:
  79       DDR:          0x00000000-0x1fffffff (max 512MB)
  80       MBAR:         0xf0000000-0xf0027fff (128KB)
  81       CPLD:         0xf1000000-0xf103ffff (256KB)
  82       FPGA:         0xf2000000-0xf203ffff (256KB)
  83       Flash:        0xfe000000-0xffffffff (max 32MB)
  84
  85 3. DEFINITIONS AND COMPILATION
