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
CONFIG_SYS_MPC8220_CLKIN Define Alaska Input Clock
CONFIG_PSC_CONSOLE Enable MPC8220 UART
CONFIG_EXTUART_CONSOLE Enable External 16552 UART
CONFIG_SYS_AMD_BOOT To determine the u-boot is booted from AMD or Intel
CONFIG_SYS_MBAR MBAR base address
CONFIG_SYS_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

5. REPROGRAM U-BOOT
===================
5.1 Reprogram u-boot (boot from AMD)
1. Unprotect the boot sector
=> protect off bank 3
2. Download new u-boot binary file
=> tftp 0x10000 u-boot.bin
3. Erase bootsector (max 7 sectors)
=> erase 0xfff00000 0xfff6ffff
4. Program the u-boot to flash
=> cp.b 0x10000 0xfff00000
5. Reset for the new u-boot to take place
=> reset
5.2 Reprogram u-boot (boot from AMD program at INTEL)
1. Unprotect the boot sector
=> protect off bank 2
2. Download new u-boot binary file
=> tftp 0x10000 u-boot.bin
3. Erase bootsector (max 7 sectors)
=> erase 0xfef00000 0xfefdffff
4. Program the u-boot to flash
=> cp.b 0x10000 0xfef00000
5. Reset for the new u-boot to take place
=> reset
5.3 Reprogram u-boot (boot from INTEL)
