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)

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
