What I tried to say is that it happens to early to connect to coreboot
using gdb support, but maybe I'm wrong.

This is option from commit message when qemu-armv7 was introduced
(7635a60). I also tried '-bios' but it gives same result but with
different address (not 0x6001024f but 0x0000024f).

What I see now is that I made mistake during bisect and it was not the
correct commit that I point to. The correct change causing problem is
exactly one before:

http://git.qemu.org/?p=qemu.git;a=commit;h=6ec1588e09770ac7e9c60194faff6101111fc7f0

Sorry for confusion - first time bisect user. This commit is directly
related to vexpress-a9 board.
