Hello,
Nokia N900 board does not work anymore from master branch in qemu. I bisected first commit which broke it. It is:
41623c91b09a0c865fab41acdaff30f060f29ad6 arm: move exception handling out of start.S files
Before this commit uboot on n900 in qemu working fine. Since this commit qemu crash with fatal error (see below). I bisected other two commits which changed error behaviour, but still uboot is not working...
