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
|
|
