-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
