This makes "-bios" actually usable on this board. Signed-off-by: Peter Maydell --- Looking back through the archives to 2012 when the vexpress-a15 flash alias went in, I seem to have been under the impression that the A9 daughterboard didn't have a similar alias, but it does. (For both boards, there is a mechanism for letting the guest dynamically remap lowmem which we don't implement; the rationale for defaulting to flash at 0 holds for both.) This is a fairly long standing bug but it's more interesting now we support -bios on this board which is a new-in-2.1 thing. Hence the for-2.1 tag. --- hw/arm/vexpress.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/hw/arm/vexpress.c b/hw/arm/vexpress.c index 3d83e6c..a88732c 100644 --- a/hw/arm/vexpress.c +++ b/hw/arm/vexpress.c @@ -84,6 +84,7 @@ enum { }; static hwaddr motherboard_legacy_map[] = { + [VE_NORFLASHALIAS] = 0, /* CS7: 0x10000000 .. 0x10020000 */ [VE_SYSREGS] = 0x10000000, [VE_SP810] = 0x10001000, @@ -114,7 +115,6 @@ static hwaddr motherboard_legacy_map[] = { [VE_VIDEORAM] = 0x4c000000, [VE_ETHERNET] = 0x4e000000, [VE_USB] = 0x4f000000, - [VE_NORFLASHALIAS] = -1, /* not present */ }; static hwaddr motherboard_aseries_map[] = { -- 2.0.0
