1552. MEMORY MAP UNDER U-BOOT AND LINUX KERNEL
156===========================================
1572.1. System memory map:
158 Flash: 0x00000000-0x3FFFFFFF (1024MB)
159 DDR: 0x40000000-0x7FFFFFFF (1024MB)
160 SRAM: 0x80000000-0x8FFFFFFF (256MB)
161 ATA: 0x90000000-0x9FFFFFFF (256MB)
162 PCI: 0xA0000000-0xBFFFFFFF (512MB)
163 FlexBus: 0xC0000000-0xDFFFFFFF (512MB)
164 IP: 0xF0000000-0xFFFFFFFF (256MB)
165
1662.2. For the initial bringup, we adopted a consistent memory scheme between u-boot and
167 linux kernel, you can customize it based on your system requirements:
168 Atmel boot:
169 Flash0: 0x00000000-0x0007FFFF (512KB)
170 Flash1: 0x04000000-0x05FFFFFF (32MB)
171 Intel boot:
172 Flash0: 0x00000000-0x01FFFFFF (32MB)
173 Flash1: 0x04000000-0x0407FFFF (512KB)
174
175 CPLD: 0x08000000-0x08FFFFFF (16MB)
176 FPGA: 0x09000000-0x09FFFFFF (16MB)
177 DDR: 0x40000000-0x4FFFFFFF (256MB)
178 SRAM: 0x80000000-0x80007FFF (32KB)
179 IP: 0xFC000000-0xFC0FFFFF (64KB)
180
1813. SWITCH SETTINGS
182==================
1833.1 SW1 Pin3: 0 - Boot from Atmel or 1 - INTEL
184 SW1 Pin4: 0 - ULPI chip not in reset state or 1 - ULPI chip in reset state
185 SW1 Pin5: 0 - Full ATA Bus enabled, FEC Phy1 powered down
186 1 - Upper 8 bits ATA data bus disabled, FEC PHY1 active
187 SW1 Pin6: 0 - FEC Phy0 active or 1 - FEC Phy0 powered down
188 SW1 Pin3: 0 - Boot from Atmel or 1 - INTEL
