| * 0x1000_0000: I/O map address |
| * 0x6000_0000: RAM |

| /* |
| * This map is designed to work with new qemu vexpress memory layout and |
| * with -bios option which neatly puts coreboot into flash and so payloads |
| * can find CBFS and we don't risk overwriting CBFS. |
| * |
| * Prior to Jul 2014 qemu aliased 0 to begining of RAM instead of flash |
| * and -bios was unusable as $pc pointed to 0 which was zero-filled as a |
| * workaround we suggested using -kernel but this still had all the issues |
| * of having fake-ROM in RAM. In fact it was even worse as fake ROM ends |
| * up exactly at addresses needed to load Linux. |
