20 * 0x8000_0000 0x9fff_ffff PCI1 MEM 512M

22 * 0xc800_0000 0xcbff_ffff LIME 64M

24 * 0xe200_0000 0xe2ff_ffff PCI1 IO 16M
25 * 0xfc00_0000 0xffff_ffff FLASH 64M
28 * CCSRBAR and L2-as-SRAM don't need a configured Local Access Window.
29 * If flash is 8M at default position (last 8M), no LAW needed.
