752. MEMORY MAP UNDER U-BOOT AND LINUX KERNEL
76===========================================
772.1. For the initial bringup, we adopted a consistent memory scheme between u-boot and
78 linux kernel, you can customize it based on your system requirements:
79 DDR: 0x00000000-0x1fffffff (max 512MB)
80 MBAR: 0xf0000000-0xf0027fff (128KB)
81 CPLD: 0xf1000000-0xf103ffff (256KB)
82 FPGA: 0xf2000000-0xf203ffff (256KB)
83 Flash: 0xfe000000-0xffffffff (max 32MB)
