154===========================================
1552.1. System memory map:
156 Flash: 0x00000000-0x3FFFFFFF (1024MB)
157 DDR: 0x40000000-0x7FFFFFFF (1024MB)
158 SRAM: 0x80000000-0x8FFFFFFF (256MB)

163
1642.2. For the initial bringup, we adopted a consistent memory scheme between U-Boot and
165 linux kernel, you can customize it based on your system requirements:
166 Atmel boot:
167 Flash0: 0x00000000-0x0007FFFF (512KB)
168 Flash1: 0x04000000-0x05FFFFFF (32MB)
169 Intel boot:
170 Flash0: 0x00000000-0x01FFFFFF (32MB)
171 Flash1: 0x04000000-0x0407FFFF (512KB)
172
173 CPLD: 0x08000000-0x08FFFFFF (16MB)
174 FPGA: 0x09000000-0x09FFFFFF (16MB)
175 DDR: 0x40000000-0x4FFFFFFF (256MB)
176 SRAM: 0x80000000-0x80007FFF (32KB)
177 IP: 0xFC000000-0xFC0FFFFF (64KB)
178
1793. SWITCH SETTINGS
180==================
1813.1 SW1 Pin3: 0 - Boot from Atmel or 1 - INTEL
182 SW1 Pin4: 0 - ULPI chip not in reset state or 1 - ULPI chip in reset state
183 SW1 Pin5: 0 - Full ATA Bus enabled, FEC Phy1 powered down
184 1 - Upper 8 bits ATA data bus disabled, FEC PHY1 active
185 SW1 Pin6: 0 - FEC Phy0 active or 1 - FEC Phy0 powered down
