15
===========================================

2.1. For the initial bringup, we adopted a consistent memory scheme between u-boot and
17
linux kernel, you can customize it based on your system requirements:
18
SDR: 0x00000000-0x00ffffff
19
SRAM0: 0x20010000-0x20017fff
20
SRAM1: 0x20000000-0x2000ffff
21
MBAR1: 0x10000000-0x4fffffff
22
MBAR2: 0x80000000-0xCfffffff
23
Flash: 0xffe00000-0xffffffff
