2. MEMORY MAP UNDER U-BOOT AND LINUX KERNEL
===========================================
2.1. System memory map:
Flash: 0x00000000-0x3FFFFFFF (1024MB)
DDR: 0x40000000-0x7FFFFFFF (1024MB)
SRAM: 0x80000000-0x8FFFFFFF (256MB)
ATA: 0x90000000-0x9FFFFFFF (256MB)
PCI: 0xA0000000-0xBFFFFFFF (512MB)
FlexBus: 0xC0000000-0xDFFFFFFF (512MB)
IP: 0xF0000000-0xFFFFFFFF (256MB)
2.2. 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:
Atmel boot:
Flash0: 0x00000000-0x0007FFFF (512KB)
Flash1: 0x04000000-0x05FFFFFF (32MB)
Intel boot:
Flash0: 0x00000000-0x01FFFFFF (32MB)
Flash1: 0x04000000-0x0407FFFF (512KB)
CPLD: 0x08000000-0x08FFFFFF (16MB)
FPGA: 0x09000000-0x09FFFFFF (16MB)
DDR: 0x40000000-0x4FFFFFFF (256MB)
SRAM: 0x80000000-0x80007FFF (32KB)
IP: 0xFC000000-0xFC0FFFFF (64KB)
3. SWITCH SETTINGS
==================
3.1 SW1 Pin3: 0 - Boot from Atmel or 1 - INTEL
SW1 Pin4: 0 - ULPI chip not in reset state or 1 - ULPI chip in reset state
SW1 Pin5: 0 - Full ATA Bus enabled, FEC Phy1 powered down
1 - Upper 8 bits ATA data bus disabled, FEC PHY1 active
SW1 Pin6: 0 - FEC Phy0 active or 1 - FEC Phy0 powered down
SW1 Pin3: 0 - Boot from Atmel or 1 - INTEL
4. COMPILATION
==============
4.1 To create U-Boot the gcc-4.1-32 compiler set (ColdFire ELF version)
from codesourcery.com was used. Download it from:
http://www.codesourcery.com/gnu_toolchains/coldfire/download.html
4.2 Compilation
export CROSS_COMPILE=cross-compile-prefix
cd u-boot-1.x.x
make distclean
