Comment is not enough to make it work. VE_NORFLASHALIAS has to be -1, then it works for me. So patch for QEMU is: diff --git a/hw/arm/vexpress.c b/hw/arm/vexpress.c index a88732c..67f266a 100644 --- a/hw/arm/vexpress.c +++ b/hw/arm/vexpress.c @@ -84,7 +84,7 @@ enum { }; static hwaddr motherboard_legacy_map[] = { - [VE_NORFLASHALIAS] = 0, + [VE_NORFLASHALIAS] = -1, /* CS7: 0x10000000 .. 0x10020000 */ [VE_SYSREGS] = 0x10000000, [VE_SP810] = 0x10001000, Unfortunately this won't fix '-bios' option only '-kernel'. So it looks like the difference is that with VE_NORFLASHALIAS=0 we have vexpress.flash0 as alias to 0x0-0x3ffffff, but without it this range is mapped to vexpress.highmem. '-kernel' parameter put coreboot.rom into highmem. Does anyone know what is the correct memory map for qemu-armv7 and where coreboot.rom should be placed ? I will try to debug '-bios' option as Peter points that address in lowmem looks better for him. I will see if this option worked in the past.
