Do you have any plans to integrate the GSM modem emulation in upstream qemu
(I ask because you are also a qemu maintainer)?

What exactly is the problem there? Qemu emulates armv5 cores for example
the versatilepb machine shows the following /proc/cpuinfo:

Processor	: ARM926EJ-S rev 5 (v5l)
BogoMIPS	: 235.92
Features	: swp half thumb fastmult vfp edsp java 
CPU implementer	: 0x41
CPU architecture: 5TEJ
CPU variant	: 0x0
CPU part	: 0x926
CPU revision	: 5

Hardware	: ARM-Versatile PB
Revision	: 0000
Serial		: 0000000000000000

Shouldn't it also handle armv4tl code? Am I wrong when I think that emulating
an armv4 within qemu would 'just' mean disabling all armv5 instructions?
