+1. SWITCH SETTINGS
+==================
+1.1 SW1: 0 - Boot from Socket Flash (AMD) or 1 - Onboard Flash (INTEL)
+ SW2: 0 - Select MPC8220 UART or 1 - Debug Card UART
+ SW3: unsed
+ SW4: 0 - 1284 or 1 - FEC1
+ SW5: 0 - PEV or 1 - FEC2
+
+
+2. MEMORY MAP UNDER U-BOOT AND LINUX KERNEL
+===========================================
+2.1. For the initial bringup, we adopted a consistent memory scheme between u-boot and
+ linux kernel, you can customize it based on your system requirements:
+ DDR: 0x00000000-0x1fffffff (max 512MB)
+ MBAR: 0xf0000000-0xf0027fff (128KB)
+ CPLD: 0xf1000000-0xf103ffff (256KB)
+ FPGA: 0xf2000000-0xf203ffff (256KB)
+ Flash: 0xfe000000-0xffffffff (max 32MB)
+
+3. DEFINITIONS AND COMPILATION
+==============================
+3.1 Explanation on NEW definitions in include/configs/alaska8220.h
+ CONFIG_MPC8220 MPC8220 specific
+ CONFIG_ALASKA8220 Alaska board specific
+ CFG_MPC8220_CLKIN Define Alaska Input Clock
+ CONFIG_PSC_CONSOLE Enable MPC8220 UART
+ CONFIG_EXTUART_CONSOLE Enable External 16552 UART
+ CFG_AMD_BOOT To determine the u-boot is booted from AMD or Intel
+ CFG_MBAR MBAR base address
+ CFG_DEFAULT_MBAR Reset MBAR base address
+
+3.2 Compilation
+ export CROSS_COMPILE=cross-compile-prefix
+ cd u-boot-1-1-x
+ make distclean
+ make Alaska8220_config
+ make
