* Memory map for qemu vexpress-a9 since

* 0x0000_0000: NOR flash

* 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.
